2 shells Mi production methods earliest is from the by-product in the carbinol production of high voltage shrewd Liu rear system gets , along with the extensive application of the synthetic carbinol technology of low voltage, associate reaction decreases greatly, 2 shells Mi industrial production technology develop carbinol dehydration or synthetic angry directly synthetic technology very quickly. Carbinol dehydration France includes liquid appearance carbinol France gentle appearance carbinol France, the reaction of the former when in liquid appearance goes on , carbinol is made by the thick dehydration of sulphuric acid, but since this France has installation scale, is little , equipment is perishable to lose , environmental pollution and operating condition bad etc. problem, had been superseded step by step. In recent years, 2 shells Mi demand increase is greater, countries again develop investment province and operating condition in succession well , the new technology of free from contamination, include the law of two steps and the law of one step mainly.
The law of two steps first from synthesis air system takes carbinol, then will carbinol under catalyst dehydration system takes 2 shells Mi. Before, make catalyst mainly with sulphuric acid, now adopts mostly from- Al2O3/SiO2SystemZSM-5Member sifts to make catalyst , performance
The law of one step from synthesis air direct system takes 2 shells Mi , include composing air to enter responder at the same time complete carbinol synthetic and two carbinol dehydration reactions and waters-Coal gas alternates reaction, outcome is carbinol with 2 shells Mi mixture, mixture separates by distillation 2 shells Mi, the carbinol return responder that does not respond. The law of one step is become normally with duplex catalyst with two kinds of catalyst mixture , is in which a kind of to compose carbinol catalyst, another kind is carbinol dehydration catalyst. Synthetic carbinol catalyst includesCu-Zn-Al( O)Base catalyst,BASF,S3-85AndI-CI-512Wait. Carbinol dehydrationSiO2- Al2O3,YType memberZSM-5Member sifts , mercerized zeolite.

Total3CO+3H2- > CH3OCH3+CO2- H=246.1 kJ / mol( 4)
Compared with the lawCOTransformation rate is higher than the France of two steps , but in the France of one step, because of 3 reactions must at the same time occur, and 3 reactions are the reaction of heat release , this asks the catalyst used to have very good hear resistance , has select-high under high temperature. The 2 shells of the law production of one step Mi use normally to make mellow wine Mi fuel, if want to produce , high pure degree need to still separate further to purify. Though, the transformation rate of the law of two steps is not as good as the law of one step, is high, but it has production technology maturation, installation adaptability is broad, post-treatment is simple to wait for characteristic, may directly build in carbinol manufacturer , may also build the good non carbinol manufacturer in other communal facility. Compared with the law of one step, the law synthetic process of two steps grows slightly, but two kinds of catalyst packs in different responder , does not disturb mutual. From the present tendency that technology develops , it is short that the law of one step has process , equipment efficiency high, operating pressure is low andCOThe transformation rate of one way higher characteristic, making the operating cost and cost of installation cost large decrease , synthetic 2 shell Mi production cost the law of two steps reduces substantially. Therefore on the law economy of one step, it is more reasonable, on market, it is with more competitiveness , in general the advantage with more technology.
According to technology characteristic and the appearance form in reaction process, come to divide , synthetic air one step legal system 2 shell Mi technology has the minute of two-phase law and three-phase law mainly. Two-phase law again weighs the law of gaseous phase(GPDME), three-phaseLPDME). The law of gaseous phase major when in regular bed responder goes on , compose air in solid catalyst surface to carry out reaction , compose air if use has carbon, catalyst surface meeting closes charcoal very quickly lose work , therefore the law of gaseous phase can only use rich hydrogen synthetic air(H2/COLong-range2), and when low transformation rate condition finishes drill to do ( do not the synthesis of reaction air plenty of cycles). The law major technical technology of gaseous phase has Denmark to hold general rope companyTIGASLaw and the JapaneseCOSMOThe jointASMTGLaw. Appearance lawCO,H2And 2 shell Mi is gaseous phase, inertia solvent for liquid appearance, suspending in the catalyst thin powder in solvent is firmly appearance. Because of liquid, thermal capacitance of appearance is big, therefore liquid appearance law very easy realization constant temperature operation, and catalyst particulate surface is surrounded for solvent, knot charcoal phenomenon is alleviated considerably, therefore it is raw material to use rich carbon synthetic air. Now, Chinese Tsinghua University and American air chemical company with JapanNKKCompany is being devoted to developing with thick liquid form responder from synthesis air one step law synthesis 2 shell Mi industrialization technology, and in last end of the century in century first difference has gone on examination, for 2 large-scale shells Mi production has established foundation.

Shandong 10 thousand tons of 2 for a long time safe chemical company's level shells Mi installation and Chongqing Britain force burn to melt the company's form bed of thick liquid the 2 law shells of one step Mi the success of installation goes into operation , sign the 2 shells of our country Mi production has the development of breakthrough, and rank among world advanced ranks.
At the20Century90Times3000t/a2 following shells Mi installation, compared with the new equipment established in recent years , scale is little , engineering technology backward, production cost is high, it is stoped production that no competitiveness and majority are in or half stop production state.
Present domestic only710T/aProduce410 thousand tons.210T/aProduce1.5Ton. The 2 shells of Chinese910T/aTake whole30%, so can say our country
In view of 2 shell Mi market prospect values , as well as 2 shells Mi the development of production technology, there are a lot of places in construction in domestic or planned construction 2 shell Mi project( technology/Scale)See from development tendency, 2 shells Mi installation scale to large scale direction development, will go to 100 thousand tons of level from 10 thousand tons of present level upgrade , and then promote million ton level; Production technology develops to the law of one step, especially liquid the appearance form bed of thick liquid the law of one step; Raw material maintains coal continuously
Now, our6Coal chemical base is planing6010 thousand tons of40The construction100The 2 biggest shells of scale on the present world of 10 thousand tons of / year Mi production line. 2 shells Mi can replace diesel oil as the fuel of automobile. It come out in large quantities can remedy the petroleum reserve of our country insufficient problem.
4, 2 shells Mi development
4.1Market
2 shells Mi is daily use industrial chemicals and chemical intermediate body etc. though profit is high, economic benefits are good , but get the restriction of market demand, now so that longer time is still impossible to become 2 shells Mi big market. Along with the development of the economy of our country, it is more rapid that petroleum consumption increases constantly, especially the demand of diesel oil increases. Our country is a petroleum stores quantity is relatively poor, the country that coal resource very much enriches , coal mine time limit is more than petroleum, how to change it using rich coal resource into clean fuel have not only used the resource advantage of our country fully with replacing petroleum products , and have important strategic meaning.
Thus it can be seen, exclude should increase the development of the product of lower reaches in the market of industrial chemicals intensity outside, 2 shells Mi industrial development should stand mainly in fuel market , this is a wide huge potential market.
4.2.Technical
Though the 2 shells of one step of legal system of our country Mi have steped solid pace, but should see clearly that on technology, we still have a lot of works to do. Since the system of scientific research of our country is being in the influence of transition stage and many factors such as the restriction of economic strength, our progress and technology of scientific research change aspect to still have a lot of problems, these metropolises directly influence us to catch the pace of world level as soon as possible.

4.3Build
2 shells Mi is fuel industry, it is to reach this purpose to ask product to compete with petroleum products, 2 shells Mi installation must have investment province, the price of raw material is low, the conditions such as certain scale, since the territory of our country is large, on region, should still build the production of different scale fully using place, the advantage of enterprise and the combination market of this area to install.
For large scale installation, it is rich to select in the( coal or natural gas) resource of raw material , the place with sufficient electric power builds factory, since raw material is cheap, scale of production is big, product cost is low, market competitiveness is strong. Large scale enterprise should bear the role of national energy mainstay.
2 shells Mi build is also a better choice in synthetic ammonia factory, it may manage with a view to communal project facility and the spare productivity of installing with synthetic ammonia factory and , technical person material, so, save investment greatly, since investment is few , may remedy because of the deficiency with the higher price of raw material, it is short to add transportation distance again, product cost may be still lower , can so have living space also.
At the Every place when development 2 shells in Mi industry should carry out social investigation fully, according to self condition and market demand, make judgment , prevent that blindness in investment causes loss to enterprise

Coal melts carbinol technology is pretty60%Above carbinol gets2005Produce570Around 10 thousand tons, part relies30The output of many 10 thousand tonses, Yan coal has invested in many coals in domestic to melt carbinol factory, too work day the carbinol project that becomes , have used local coal and burnt stove angry two resource productions carbinol, not only cost is more low, at the same time, there is the certain meaning of environmental protection.
Carbinol has been tested as new energy fuel, extensively in domestic, every index is better than petrol, 2 shells Mi have been the new energy fuel of international recognized cleaning and efficiency. Shanxi province when carbinol goes as automobile on application fuel in domestic front row, through domestic and international extensive n, carbinol does not be lower than petrol as the performance of replacing performance source, domestic has begun to have carbinol vehicle put out , 2 shells Mi have been the new energy material of international recognized and key development.
50.1040501 billionShell Mi is the material synthesises such as natural gas a kind of may burn gas, since without sulphur and carbon ash, when burning , will not leave the poisonous material of the pollutive airs such as vulcanization thing and fume, therefore very environmental protection. Shell Mi production usually divide into two steps - - first becomes natural gas and methane gas carbinol, then use catalyst again to compose shell Mi. The problem that produces so is shell Mi production cost error is high, from technology, consideration carries out plenty of productions to still have a lot of difficulties, so cause shell Mi price is always at a unchanged high level , present liquid shell of 1 kgs Mi price will be more expensive and more a lot of than diesel oil, have also obstructed use from this shell Mi is automobile fuel , generate electricity the substitute of fuel or family coal gas.( technology)But recently, expert has studied produce shell in large quantities with low cost Mi new technology, the place of its key has discovered may be the direct synthesis of raw material shell Mi, with the new catalyst that copper, zinc and alumina system become; Also improve on synthetic method, so as make catalyst ample performance its role. At the same time along with expert for shell Mi production new technology perfect further, estimating last production the shell that happens Mi price will decrease 75%May use shell from this Mi replacing diesel oil is fuel, and it need to be for the oil box of the automobile of diesel oil reform slightly with compressed pump can; At the same time because of shell Mi performance is very similar with coal gas, may use shell therefore Mi the substitute as family coal gas.
