拯救中国生态环境必由之路——煤炭气化加氢制甲醇的煤炭现代化利用途径

我国能源消费结构中煤炭占70%,传统的煤炭消费方式给我国环境造成了灾难性的危害。文章分析了我国煤炭传统利用方式带来的污染物排放量。为了实现我国提出的生态现代化目标,提出了煤炭气化配水电解产生的氢制甲醇的煤炭现代化利用工艺,并与目前正在推行的煤炭直接、间接液化工艺进行了比较。结论是前者比后两者的能源利用率更高,对环境更友好,是拯救中国生态环境的必由之路。

Approach to Save the Environment in China——the Way Utilizing Coal to Produce Methanol by Coal Gasification and Hydrogen Addition Process

The coal consumption amount is about 70% in the total energy consumption in China.The traditional consumption way of coal brings great disastrous effect on environment. This paper analyzes the amount of various contaminator produced by the coal traditional utilizing way.To realize the goal of environmental modernization in China,the paper proposes the process of coal gasification and hydrogen addition with the hydrogen from water electrolyzing to produce methanol,and compares it with coal direct and indirect liquefying processes which are popularized recently.The conclusion is that the former is more friendly to enrironment,its utilizaton ratio of energy is higher than bath the latter,so it is the only approach to save the environment in China.
