耦合联产开发煤化工清洁利用技术展望

Prospect of Clean and Efficient Coal Chemical Technology Using Integrated Combined Utilization Theory

非化石能源代替传统能源发展的必然,核能、风能、光能的发电比逐年提高,但受配电网等限制,西北地区弃电率高达50%,能源产生浪费,而超级容量电能储存技术仍未得到全面突破,若将弃电能转化为化学能储存利用,如氢能等。随着碳排放交易规定推行,煤化工产业已经逐渐从粗放型生产转变为清洁利用型将,同时多炭缺氢因素已变成制约煤化工技术发展瓶颈,若能将发电、电能、氢能储能、煤化工技术联产耦合,既提高电能利用效率、又提高了煤炭利用率,并全面降低煤化工对环境的污染。

Renewable energy instead of traditional Fossil energy is the necessity of industrial development, such asnuclear, wind and light energy, their utilization ratio increases each year. Limited by the distribution power grid inNorthwest China, the rate of abandoned energy is over 50%. In the 21stcentury, the technology of super electric storageis a bottleneck of constrainted development, if the abandoned electric energy is converted into the chemical energy. Forexample, electric energy conversion of hydrogen energy can improve the energy utilization efficiency. With the regulationsof arbon trading is promulgated, the coal chemical industry from crude production mode to integrated combined cycleutilization technology will be the development of trend, the lack of hydrogen in coal chemical industry will be thebottleneck of coal chemical technology. Coupled the technology industry of power generation、 electric energy, hydrogenenergy storage, coal chemical industry, the efficiency of energy utilization was enhanced.
