No.8 石炭バイオマス共ガス化を目的とした三塔式循環流動層ガス化システムの開発(ガス化・燃焼・液化(1))

抄録

We developed a three reactors circulating fluidized bed process for biomass and coal co-gasification. The three reactors are constructed as a tar reforming reactor, a gasifier and a combustor in circulating fluidized bed system. The circulating material is CaO made from limestone. The CaO works like heat transfer material, tar reforming catalyst, CO_2 sorbent, and sulfur sorbent. Three tower CFB biomass-coal co-gasification process by using CaO particles as circulating material were investigated with Aspen plus.
