Abstract

It is a potential technology to separate CO2 at a low temperature(40—80℃)by using amine functionalized porous material.For the application of this technology

it is crucial to realize continuous CO2 separation using dual-fluidized bed reactors.In this work

a dual fluidized bed reactors system based on supported amine sorbent was built to simulate continuous CO2 capture from flue gas.The supported amine sorbent was prepared by impregnating polyethylenimine(PEI)with molecular weight of 600 on porous silica gel Q-10.The experimental results indicated that the supported amine sorbent successfully circulated between the absorber and the regenerator and the long-term and continuous separation efficiency reached up to 84.4% without steam.And separation efficiency was improved about 97% with 1.0%(vol) steam introduced.
