New nickel catalysts supported on highly porous alumina intercalated laponite for methane reforming with CO2

Alumina intercalated laponite (Al-laponite) was prepared with a polyethylen e oxide (PEO) surfactant and used as supports of nickel catalysts for the c arbon dioxide reforming reaction with methane to synthesis gas. The effects of the supports of intercalated laponite and catalyst preparation on catal ytic activity, stability and carbon deposition were investigated for the ab ove reforming reaction. We found that the pore structure of the Al-laponite supports can be tailored with the surfactant and the catalyst with well-de veloped porosity exhibited higher catalytic activity and a longer time of c atalyst stability.
