Patent DE-2261634-A1 (DE)
Title: Steam reforming of hydrocarbons to methane - on nickel catalysts, in two-stage process
Inventor: BROECKER FRANZ-JOSEF DR
IPC: C10G51/02
Filed: 1972-12-16
Abstract: A mixt of 2-30C hydrocarbons with steam is partially cracked in a first reaction zone over a Ni catalyst to give a prod stream also contg. unreacted hydrocarbon. After cooling this is further reacted in a second zone over a Ni catalyst in the presence of steam to give a mixt of CH4, carbon oxides, H2 and steam. The catalyst in the first zone is pref. used until 75% of the hydrocarbon remains unreacted. It may then be replaced and used as the second zone, while the partially used catalyst from the second zone is used as the first. The catalyst is a type with low temp. activity, esp. one produced from a precursor of formula Ni5MgAl2(OH)16.CO3.4H2O. The process is highly economic, since the first zone can be operated with low steam to hydrocarbon ratios and with high catalyst loadings. Life of the catalyst is extended.
