バイオマスガス化発電用乾式ガス精製システムの開発

摘要

Dry gas cleaning system for impurities removal is required for efficient power generation with biomass gasification technology. A pilot scale dry gas cleaning plant was constructed to demonstrate the performance of multiple impurities removal from biomass derived gas produced by biomass gasifier. Sufficient performance for impurities removal was attained with hydrated lime injected bag filter, copper based mercury sorbent, glass fiber reinforced halide sorbent and zinc oxide sulfur sorbent. The purified biomass derived gas was available for stable power generation with molten carbonate fuel cell (MCFC). This result demonstrated that the dry gas cleaning system satisfied the performance requirement for the biomass gasification power generation system.%電中研が開発?選定した不純物除去剤を適用したパrnイロットプラント規模の乾式ガス精製設備を用いて，rnバイオマスガス化ガスに含まれる不純物の除去性能試rn験を行った．ガス化炉で製造した実ガスをMCFCで発rn電可能な清浄度まで精製することに成功し，高効率なrnバイオマスガス化燃料電池発電に適用可能な乾式ガスrn精製システムの一貫性能を実証した．
