摘要: 回顾了以煤和天然气为原料通过不同工艺流程制备合成气用以化工合成或发电的研究进展。介绍了以煤和天然气为原料分别制取合成气后再汇合的工艺流程和共气化技术等不同工艺路线的特点。研究了煤气化和天然气转化制备合成气时不同工艺路线在元素互补、能量利用、杂质混合等方面的表现。结果表明是否考虑煤和天然气的碳氢元素互补以及煤气化热量的有效利用将成为决定工艺流程优劣的重要因素。研究表明,煤气化和天然气转化分别制备合成气后汇合的工艺技术更易实现工业化应用,共气化技术的工业化应用较易受到气化炉反应条件的限制,尤其是内置换热管式的共气化技术。进行比较后,认为以煤和天然气为原料的多原料系统能够降低原料消耗、同时减排二氧化碳,符合煤炭的清洁利用要求,具有一定优势。

Abstract: This paper reviewed the research progress of coal and natural gas as raw materials to produce syngas,which can be applied to chemical synthesis or power generation. The features of two processes on production system using coal and natural gas as raw materials to produce syngas were introduced. One is coal and natural gas produced syngas separately and then converged and another co-gasification process. The results showed that the characteristics of elements of coal and natural gas and heat utilization of gasification were the key factors to select the process. The process of coal and natural gas produced syngas separately and then converged was simple to operate and easy to be industrialized. The industrialization of co-gasification process was limited by the reaction condition. Compared with traditional industrial system with single feed syngas preparation,the multi-feed system by coal and natural gas could decrease the consumption of raw materials and the CO2 emission. This process meets the clean coal utilization,which should be encouraged.

Key words: co-feed systems, gasification, process systems, syngas, heat utilization
