摘　　要：天然气 -煤共气化新工艺是基于天然气蒸气转化法和煤气化工艺进行耦合发展起来的新型工艺。本文分析了该工艺的技术原理 ,理论上可以直接制备H2 /CO为 1～ 2可调节的合成气 ;详细地介绍了天然气 -煤共气化新工艺的主反应设备合成气制备炉的结构及工艺流程 ,通过对该工艺过程的热力学和动力学分析得出工艺的最优工艺参数 ,通过试验可以直接制备出H2 /CO为 1～ 1 5、可调节的合成气 ,从而证明该工艺过程的可行性 ,并指出天然气New preparation process of synthesis gas from natural gas and coal by co-gasification is a new type process developed coupling by natural gas steam method and coal gasification. Analyzed the technology principle of this process in this paper, which can prepare synthesis gas H 2/CO =1～2 controlled by ourselves in theory directly. Introduced the gasifying furnace and flow schematic diagrams of this process in details. Got the optimal process parameters by analyzed thermodynamics and kinetics of preparation process and prepared synthesis gas H 2/CO =1～1 5 controlled by ourselves by experiments, which proved feasibility of this preparation process. Pointed natural gas & coal co-gasification is an excellent preparation technology worth exploiting.
