Technical and Economic Analysis on Syngas Production from Biomass Gasification

The processes and routes of syngas production from biomass gasification were first outlined, and the key processes of this technology were highlighted in the paper. Simultaneously, the cost of syngas production from biomass gasification was evaluated to be RMB 1.05/Nm(3) when the handling capacity of gasifier, material cost and system operating rate is separately fixed to be 1ton/h, RMB 250/ton and 0.8. On this basis, the influences of these three aspects (handling capacity of gasifier, material cost and system operating rate) on the syngas production cost were analyzed. It could be concluded that the reduction in the syngas production cost could be achieved by raising handling capacity of gasifier, reducing material cost and enhancing system operating rate. Finally, the prospect of this technology was put forward from technical and economic points of view.
