摘要

1451862 Steam reforming JAPAN GASOLINE CO Ltd and NIKKI CHEMICAL CO Ltd 15 Jan 1974 [22 March 1973 20 June 1973] 01842/74 Heading C5E Methane-containing gas is produced by contacting a mixture of at least one hydrocarbon having at least 2 carbon atoms and steam preheated to 250-260‹C. and in a H 2 O:C ratio between 0À9 and 5 with a nickel-containing catalyst which has been activated in a stream of hydrogen gas, has a temperature of 300- 600‹ C., comprises metallic nickel and a solid solution of nickel oxide and magnesia and has a Ni/Mg atomic ratio of from 0À05 to 7À0. The steam reforming reaction can be carried out at 0-100 kg./cm.SP2/SPG. Suitable feeds are refinery off gas, LPG, naphtha and kerosene. The catalyst can comprise up to 70 wt. per cent of α-Al 2 O 3 , SiC, α-quartz or ZrO 2 as a carrier and copper-chromium oxide or copper-chromiummanganese oxide in an amount of up to 25 wt. per cent, based on the amount of metal relative to the content of nickel in the catalyst.
