Low temperature steam reforming process for hydrocarbons

Patent ·
OSTI ID:7013359
A new Japanese-developed low-temperature gasification process for producing methane-containing gases prolongs catalyst life and reduces deposition of carbonaceous matter on the catalyst. The steam-reformable hydrocarbon feed (such as refinery off-gases, LP-gas, naphtha, or kerosene) and steam preheated to a temperature of 482/sup 0/ to 1112/sup 0/F at a steam/feed ratio of 0.9 to 5.0 in terms of H/sub 2/O/C (mole/atom) is introduced into a steam-reforming reactor (or reactors) packed with a novel nickel-magnesia-carrier catalyst. The catalyst is so prepared that the atomic ratio of nickel to magnesium is in the range of 0.5 to 5.0 (preferably 1.0 to 3.0), and an inorganic refractory carrier--free of chemical reaction with associated components during the reforming--is a component representing an amount of not more than 70 wt% relative to the whole amount of the catalyst. The steam-reforming reaction occurs at a pressure in the range of 150 to 1500 psig; the temperature of the catalyst bed is maintained in the range of 572 to 1112/sup 0/F, preferably 752 to 1058/sup 0/F.
