Hydrogen Production Performance of CuO/ZnO/Al2O3 Structured Monolithic Catalyst with Stainless Steel Fiber Felt for Methanol Steam Reforming
Using commercial porous stainless steel fiber felt(PSSFF)prepared by cutting method as catalyst carrier,the CuO/ZnO/Al2O3 monolithic catalyst was prepared by impregnation method,and its effect on hydrogen production from methanol steam reforming was studied.The microstructure of the monolithic structured catalyst of porous stainless steel fiber felt was characterized by scanning electron microscopy(SEM).By changing the reaction space velocity and reaction temperature,the hydrogen production performance of the microreactor and the fixed bed reactor was investigated.The results showed that compared with the fixed bed reactor,the structured catalyst and microreactor filled with PSSFF can enhance the mass transfer and heat transfer of the reaction.At the reaction temperature of 280℃,the hydrogen molar flow rate was 0.55 mol/h,and the methanol conversion rate was 95.07%.PSSFF structure monolithic catalyst can reduce the reaction temperature of methanol steam reforming and reduce the energy consumption of the reaction system.
