Abstract
Gasification power generation plant has significant potential for highly efficient utilization of biomass and refuse derived materials. This work evaluates the performance of the dry gas cleaning system for the power generation plant and to examine its feasibility in commercial scale. Sorbents for impurity removal was prepared as copper based mercury sorbent, glass fiber reinforced halide sorbent and zinc oxide sulfur sorbent. Performance evaluation in the demonstration plant showed sufficient performance for various impurities. Power generation test with the molten carbonate fuel cell (MCFC) was also successful in accomplishing stable power generation with the MCFC. The commercial scale plant of dry and wet system was designed and compared, which showed large advantage of the dry system. These results confirmed that the dry gas cleaning system is sufficiently feasible to establish the biomass gasification based power generation system.
