一种煤气化制甲烷的设备及方法
摘要：
本发明的实施例提供一种煤气化制甲烷的设备及方法，所述煤气化制甲烷的设备包括气化炉和第一气固分离装置，所述气化炉包括第一气化段和第二气化段，所述第一气化段出气与所述第二气化段连通，所述第一气固分离装置同时与所述第一气化段和所述第二气化段连通，所述第一气化段用于使煤和气化剂发生反应，生成第一气体产物，所述第二气化段用于使所述第一气体产物和煤粉发生反应，并生成包含甲烷的第二气体产物，所述第一气固分离装置用于从所述第二气体产物中分离出含碳的固体产物和含甲烷的第三气体产物，并将所述固体产物送回所述第一气化段。本发明提供的煤气化制甲烷的设备用于制备富含甲烷的煤气。
摘要（英）：

The invention provides a device and a method used for preparing methane via coal gasification. The device comprises a gasifier and a first gas-solid separating unit; the gasifier comprises a first gasification segment and a second gasification segment; the first gasification segment is communicated with the second gasification segment; the first gas-solid separating unit is communicated with the first gasification segment and the second gasification segment at the same time; the first gasification segment is used for reacting coal with a gasifying agent so as to obtain a first gas product; the second gasification segment is used for reacting the first gas product with coal powder so as to obtain a second gas product containing methane; the first gas-solid separating unit is used for separating a carbon-containing solid product and a methane-containing third gas product from the second gas product, and delivering the carbon-containing solid product to the first gasification segment. The device is used for preparing gas rich in methane.
