从统计资料来看,我国石油对外依存度高达50%,天然气虽然进口量不多,对外依存度仅5%,但占一次能源消耗的比重不足5%,远低于20%的世界平均水平,因此随着国内需求越来越大,供应越来越紧张。而我国煤炭资源相对丰富,加上国际油价不断上涨,各类新型煤化工不断的发展起来,除了前几年快速发展导致目前产能过剩的煤制甲醇、二甲醚、醋酸等,近些年又将关注点转移到了煤制天然气、煤制烯烟、煤制油、煤制乙二醇等,并且地方政府及企业规划建设的规模和数量都很大。
From the statistical data, China’s oil dependence on foreign countries as high as 50%, although the import volume of natural gas, foreign dependence is only 5%, but accounted for less than 5% of primary energy consumption, well below the world average of 20% Therefore, with the increasing domestic demand, the supply is getting more and more nervous. However, due to the relative abundance of coal resources in our country and the rising international oil prices, various new types of coal chemical industry have been continuously developed. In addition to the rapid development of previous years, coal-based methanol, dimethyl ether and acetic acid with overcapacity have emerged. In recent years, The focus shifted to the coal-to-natural gas, coal-based enamels, coal-to-oil, coal-to-ethylene glycol, etc., and the scale and number of local government and corporate planning and construction are large.
