1、Coal Chemical Industry,By Wangfeng,content,1.What is coal chemical industry? 2.The present situation of coal chemical industry. 3.The prospect of coal chemical industry.,1.What is coal chemical industry?,Coal chemical industry refers to coal as raw material, through chemical processing of coal into
2、gas, liquid and solid fuels and chemicals. Including coal gasification, liquefaction, carbonization, and the processing of tar and calcium carbide acetylene chemical industry etc.,2.The present situation of coal chemical industry.,The industry of transferring coal into gas, liquid, solid product or
3、semi finished article, and further processing it into a series of chemical industrial products or oil fuel is addressed as coal chemical industry. Technically speaking, coal chemical industry includes coal coking, coal gasification and coal liquefaction.,1.Methanol,Chinas Methanol producers totaled
4、187 in 2006.the capacity reached 13444000 ton/year, and the output reached 8747000 ton/year. The import volume of Methanol reached 1127000ton in 2008,the apparent consumption reached 9684000 tons and the year-on-year growth rate of Methanol consumption reached 45%.,1.Methanol,During the 10th five-ye
5、ar plan period, the annual Methanol capacity increased by over 20%.A batch of tens of thousands ton, and even hundreds of thousands to equipment have been under construction successively. Methanol can be used for the production of dimethyl ether, olefin and oil products. It is predicted that for a t
6、ime its capacity shall remain swift growth and hence might become a highlight in the development of coal chemical industry.,2.Coke,Chinas coke industry is mainly located in cooking coal producting areas and big provinces of iron & steel.The provinces whose coke capacity exceed 10 mn ton include：Shan
7、xi Hebei Shandong Henan LiaoningSince the 10th five-year plan,all provinces enhanced efforts in their industrial stucture adjustment.Hence the product structure and industrial centralization degree of the coke industry made some changes.The proportion of Mechanical coke rose from72% of 2000 to 95% o
8、f2005.,2.Coke,At present, more than 1mn ton/year coke enterprises in China exceeded 42 in number. In addition to coking equipment assorted for the iron & steel enterprises, most enterprises dont reach the original economic scale, and the recycling and use of coal tar and coke oven gas is limited.Abo
9、ut 80% of Chinas coke products are for the use of iron & steel industry, with one quarter or so surplus in capacity. The export volume stood at 12.76 mn ton in 2005.,3.Calcium carbide,Chinas calcium carbide industry is mainly located in areas with lower coal, power and coke prices. Therein, the capa
10、city of calcium carbide in lnner Mongolia, Ningxia and Shanxi exceeded 1 mn tons. In recent years the industrial structure of calcium carbide was adjusted progressively.So far, the enterprises of more than 100000-ton capacity number 10, and the rest are small plants.Calcium carbide products are main
11、ly used for the PVC production, with one half capacity left unused. Developing calcium carbide stove brings about severe pollution to the environment.,4.Fertilizer,Coal-generated fertilizer is mainly located in coal production place and large agricultural provinces,among which the follwing provinces
12、 exceed 2 mn tons in capacity: Shanxi Jiangsu Henan Shandong Hunan,4.Fertilizer,Raw material and power structure adjustment has been conducted in the fertilizer industry in recent years. Via advanced coal gasification technology and CHP technology, traditional industry is reconstructed, the industry
13、 develops in a swifter speed, the industrial centralization degree improves gradually, and over 20 enterprises have reached proper economic scale (annual output of synthetic ammonia reaching 200000 tons） Coal generated fertilizer accounts for 70% or so of the total capacity, mainly used for the agri
14、cultural production., the supply and demand basically keep a balance. Most enterprises use anthracitic range coal of Shanxi jincheng as raw materials in their production.,5.Dimethyl ether,Dimethyl ether is a new coal chemical product developed in recent years. The national DME capacity of 2002 stood
15、 at 30000 tons,and that of dimethyl ether of 2005 stood at 300000tons or so, 100000-ton production equipment have been constructed in Sichuan Lutianhua and Shandong Jiutai respectively,ranking top world wide. Dimethyl ether can be used as civil fuel and disel subordinate. The repalcement of diesel w
16、ith dimethyl ether is being carried out in Shanghai,etc, some enterprises,such as Xinao Group, are carrying out the replacement of civil fuel with dimethyl ether.,6.MTO,Dalian Institute of Chemical Physics, CAS, Shanxi Xinxing Coal Chemical Technology Ltd, and Luoyang Petrochemical Engineering Corpo
17、ration Sinopec jointly constructed the 1st industrial DMTO test equipment in the world, whose treatment capacity reached 50 ton/day. The technical indicators of the equipment are: Methanol conversion rate close to 100%, LC olefin （ethylene, propylene, butene）choice90%,6.MTO,The 600000 ton/year DMTO
18、project constructed in Baotou City, inner Mongolia, by Shenhua Group Corporation, Limited via DMTO technology of independent intellectual property right has obtained approval from the State Development and Reform Commission. The project shall construct 1.8 mn ton/year Methanol equipment,600000 ton/y
19、ear polypropylene equipment.,7.Coal liquefaction,Direct coal liquefaction of coal in hydrogen and catalyst, the hydrogenation cracking into a liquid fuel called direct liquefaction. Cracking is a hydrocarbon molecule splits into several small molecular reaction processes. Because of coal direct liqu
20、efaction process mainly uses the hydrogenation, so called coal hydrogenation liquefaction method. The shortage of petroleum, liquefied coal products can replace natural oil. Indirect liquefaction of coal indirect liquefaction is using coal as raw material, first gasification syngas, and then, throug
21、h the catalytic conversion of synthesis gas to the process of hydrocarbon fuel, alcohol fuels and chemicals.,3.The prospect of coal chemical industry.,In 1984 the World fossil fuel reserves of recoverable reserves, coal accounted for about 74%, and about 12% oil, natural gas is about 10%, from a res
22、ource perspective, coal will be the main raw material of chemical potential. Since twenty-first Century, the international energy prices have been rising fast. The crude oil, natural gas prices rose sharply, while the coal price increase is relatively small, and the oil, natural gas prices continue
23、to expand,Since the second half of 2012, differences between coal and crude oil price performance, make the coal be promoted as a raw material cost advantage, economy of coal chemical industry gradually.The unique structure of energy in our country but also enhance the inevitability of the developme
24、nt of coal chemical industry, the future of Chinas coal chemical industry, especially the new coal chemical industry is expected to usher in rapid development.Coal chemical industry and petrochemical industry with mutual substitution, such as coal chemical production of olefins, oil products are the main products of the petrochemical industry. The development of new coal chemical industry can be added as a Petrochemical good, has a strong strategic significance.,THE END! THANK YOU!,
