整体式催化剂催化重整净化生物质粗燃气性能研究

The Nibased monolithic catalyst was prepared by impregnation. The performance of the monolithic catalyst for the reforming of biomass fuel gas was studied at 750℃ for 108h. The results show that over the monolithic catalyst , the average CH4 conversion reaches 92%. The maximum conversion of CH4 is 93.8% . The average H2/CO mol ratio is 0.95 and the maximum H2/CO mol ratio is 1.15 . The conversion of CO2 reaches up to 88%. Naphthalene was added as the tar model compound. It is found that the tar is completely converted to H2, CO and trace lighter hydrocarbon compounds. The catalyst kept its activity during the 108h reaction. No pressure drop was detected in the reactor, which shows that the catalyst has excellent reforming activity and anticoking performance.
