Hydrogen production with integrated CO2 capture in a novel gas switching reforming reactor: Proof-of-concept

摘要

This paper reports an experimental investigation on a novel reactor concept for steam-methane reforming with integrated CO2 capture: the gas switching reforming (GSR). This concept uses a cluster of fluidized bed reactors which are dynamically operated between an oxidation stage (feeding air) and a reduction/reforming stage (feeding a fuel). Both oxygen carrier reduction and methane reforming take place during the reduction stage. This novel reactor configuration offers a simpler design compared with interconnected reactors and facilitates operation under pressurized conditions for improved process efficiency.
