Abstract

<PICT:0993974/C1/1> The carbon monoxide content of gases containing hydrogen produced according to the parent Specification by the cyclic catalytic conversion of hydrocarbons is decreased by contact at 350-550 DEG C. with a nickel-based catalyst to produce CH4 and CO2. In the parent Specification liquid or gaseous hydrocarbons are converted by steam in successive cycles which consist of a heating and conversion phase separated by steam scavenging, the catalyst layer being positioned on a gas or liquid pervious support and the heating gas, steam and conversion gas being passed therethrough. H2 reduces the CO in an exothermic reaction to CH4 and steam, and further CO then reacts with the steam producing CO2 and H2. The proportion of CO converted is increased by increasing the proportion of steam mixed with the initial hydrocarbon at the entrance to the primary conversion furnace. Combustion gases for heating the primary conversion furnace and reducing gases for reducing the consequently oxidized catalyst 2 enter through 3 and are normally discharged through damper 8. However, if the original hydrocarbon contains sulphur, the combustion gases are passed through the catalyst 6 whereby any NiS formed is oxidized to NiSO4 from which Ni is regenerated by H2. Steam and hydrocarbon are added through 9 and 10 and after passage through the catalyst 2 the manufactured gas is cooled to 350-550 DEG C. by the heat exchanger 4. After entering the secondary conversion furnace the gases pass through 6 which comprises one or more layers of a Ni-based catalyst similar to one of those described in the parent Specification and Specifications 807,358 and 810,265. The gaseous product is discharged through the pipe 11.ALSO:<PICT:0993974/C4-C5/1> The CO content of gases containing H2 produced according to the parent Specification by catalytic conversion of hydrocarbons is decreased by contact at 350-550 DEG C., with a nickel based catalyst to produce CH4 and CO2.
