论述了我国煤炭热能利用现状;阐述了煤炭气化过程中元素物料的化学反应原理和热能增值利用的基本原理;从物尽其用的观点出发,介绍了煤炭清洁转化同水电解氢制取甲醇的工艺路线;通过对比壳牌粉煤气化和德士古水煤浆气化工艺的气化数据,提出了利用我国已引进的壳牌气化炉的多项煤炭综合利用途径:①煤炭同水电解氢制甲醇采用粉煤纯氧气化,甲醇弛放气联产合成氨和尿素;②甲醇油催化用作汽车燃料;③煤制甲醇脱水制取烯烃;④创新型120万t/a甲醇联产合成氨和尿素工艺流程。
The present situation of coal thermal energy utilization in China is expounded; the basic principle of chemical reaction principle of elemental materials and value-added utilization of thermal energy in coal gasification process are expounded; from the viewpoint of making the best use of coal, By comparing the gasification data of the Shell pulverized coal gasification and the Texaco coal gasification gasification process, a number of comprehensive coal utilization ways utilizing the Shell gasifier that our country has introduced are put forward: (1) Methanol produced by pure coal gasification of pulverized coal, methanol, methanol and synthetic gas to release ammonia and urea; Catalytic use of methanol as a motor vehicle fuel; ③ Coal methanol dehydration to olefins; ④ Innovative 1.2 million t / a methanol co-production of ammonia and Urea process.
