A gasification reactor is provided. The reactor comprises a first gasification area, a second gasification area and a shared combustion area. The shared combustion area is set between the first and second gasification areas. Therein, the (present invention applies interconnected fluidized beds in gasification. The connecting piping between the first and second gasification areas are separately replaced with dense beds to be integrated for forming a single reactor. Thus, the present invention simplifies the system, saves the cost and reduces the operation difficulty.

Gasification reactor with shared partial reactor vessels

A chemical looping reactor is provided. The reactor comprises a first reduction reactor, a second reduction reactor and a shared oxidation reactor. The shared oxidation reactor is set between the first and second reduction reactors. Therein, the present invention applies interconnected fluidized beds in chemical looping combustion. Single redox is processed with oxygen carrier (oxide of metal like nickel or copper). The first and second reduction reactors individually handle their own reactions and reactants. Thus, in a chemical looping reactor, two different source materials can be handled at the same time. The oxygen carrier can be cycled separately as well for fully releasing oxygen contained within. High-purity carbon dioxide is further obtained. The application can be extended to hydrogen generation. Hence, the present invention simplifies the reaction mechanism, enhances the yield, improves the operation efficiency and reduces the cost.
