摘　　要：分析了煤与重质油共气化过程和热力学特点,应用流程模拟软件Aspen Plus对焦炭和渣油系统进行了热力学能量和物料平衡计算,从热力学角度进行了可行性研究。结果表明,煤与重质油共气化技术可以制备低碳烯烃并联产合成气,低碳烯烃(C2H4+C3H6)含量大于15%,合成气(H2+CO)含量大于60%,CO2含量小于1.5%,且能有效地解决重质油裂解造成的结焦问题。The coal and heavy oil co-gasification process is introduced in this paper. The principle of this process and the thermodynamic characteristics are presented. The energy and mass balance calculations of coal and heavy oil co-gasification are made by using Aspen Plus. The results indicated that coal and heavy oil co-gasification can produce light olefins and synthesis gas, the content of light olefins （C2H4＋ C3H6） is more than 15%, the content of synthesis gas （H2 ＋ CO） is no less than 60%, and the content of carbon dioxide is less than 1.5%, and the coking problem of heavy oil gasification can be resolved.
