Mixed reforming of simulated gasoline to hydrogen in a BSCFO membrane reactor

摘要

Currently,fuel cells are receiving more and more attention as the most promising new power generation technology,and fuel processing by the mixed reforming of liquid hydrocarbons (MRL) with water and oxygen is regarded as a desirable way for fuel cells.In this paper,we developed a new mixed reforming method for hydrogen production by combining a dense ceramic membrane Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-delta)(BSCFO) with a catalyst LiLaNiO/gamma-Al_2O_3 in a membrane reactor and reforming a simulated gasoline.During a 500-h long-term test at optimized reaction conditions,all the components in the simulated gasoline converted completely,and around 90% selectivity of CO,around 95% selectivity of H_2 and around 8.0 mL cm~(-2) min~(-1) oxygen permeation flux were achieved.This provides a new optional way of hydrogen production for fuel cells.
