No.8 Study on a Three Reactors Circulating Fluidized Bed Process for Biomass and Coal Co-gasification

Abstract

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.
