Abstract
A method of continuously producing town or grid gas comprises cracking liquid or gaseous hydrocarbons or hydrocarbon-rich refinery exhaust gases with steam in an indirectly heated reactor, e.g. a tube reactor, at 700 DEG to 800 DEG C, adding liquid or gaseous hydrocarbons or hydrocarbon-rich refinery exhaust gases to the cracked gas, and subjecting the mixture to a catalytic hydrogenating cracking reaction at 500 DEG to 700 DEG C. The temperature of the second reaction, and the quantities of the reactants in the second reaction, are controlled so that (a) the H2 content of the gas from the second reaction is the same as or less than that of the gas from the first stage, and (b) the volumetric ratio H2 to CO in the second gas is the same as or greater than that in the first gas, i.e. the CH4 and CO2 content of the gas is increased by the second reaction. The first cracking reaction, which may include air, may be carried out at normal or elevated pressure, e.g. 10 to 25 atmospheres, using a nickel-containing catalyst. The second cracking reaction, which may include steam, is preferably carried out at 550 DEG to 650 DEG C., and a cobalt-molybdenum or nickel-containing catalyst is used. Hydrocarbons supplied to both reactions include propane, butane, and light and heavy petrol. After leaving the reactor, the cracked gas may pass through a heat exchanger, e.g. to raise steam or to preheat crude stock, after which the further hydrocarbon, with or without steam, is added. After leaving the second reactor, the gas passes through a second heat exchanger and a carbon dioxide scrubber, and hydrocarbons, refinery exhaust gas and air may be mixed with the gas to adjust its calorific value and oxygen content. A specific example is described.
