摘要：
To deal with the problem of tar production during biomass gasification，the ZSM-5/Ni Foam is used to explore its catalytic performance，which is prepared by impregnation method with Ni Foam as nickel source and carrier and ZSM-5 as active additive. The catalytic cracking of biomass tar is carried out in a segmented fixed-bed reaction system. The results show that when the acidic ZSM-5 is supported on the ideal three-dimensional framework structure of Ni Foam，the ZSM-5/Ni Foam not only increases the contact area between biomass tar and catalyst active sites，but also slows down the formation of carbon deposition during the catalytic process，thereby obtaining higher catalytic performance with the tar conversion rate reaching 90.2%. The ZSM-5/Ni Foam catalyst possesses good catalytic activity and cycle stability. At the same time，this paper also reveals the catalytic mechanism of ZSM-5/Ni Foam. © 2024 Science Press.
