Hydrogen Production from Coke Oven Gas by CO 2 Reforming Over a Novel Ni-Doped Silicalite-1
2018
A series of in-situ nickel atoms doped (Ni-doped) Silicalite-1 used as the catalysts in dry reforming of coke oven gas (COG) have been synthesized by one-pot hydrothermal method. These catalyst materials are characterized by electron microscopy, X-ray powder diffraction, and Nitrogen adsorption–desorption measurements, etc. And the catalytic results show that in-situ Ni-doped zeolites exhibit superior performance for dry reforming of COG. Moreover, the in-situ synthesized Ni-doped Silicalite-1 catalysts with trace amount of nickel behave quite considerable activity and outstanding anti-coking property in comparison with the traditional Ni-based catalysts. The method we adopt in this work is less complicated for the synthesis of Ni-doped Silicalite-1, which will make the in-situ Ni-doped Silicalite-1 catalysts have great prospects for hydrogen production from COG by CO2 reforming in the future.
