Hydrocarbons are thermally gasified with oxygen and water vapor as gasifying agents under a pressure of at least 3 kilograms per square centimeter and at temperatures in the range of about 1,000-1,500 DEG C in a reactor having supply conduits for the hydrocarbons, the gasifying agents, and an inert purging gas. The hydrocarbon and gasifying agents supply conduits are opened and closed by suitable valves and means are provided for scrubbing the product gas which contains mainly carbon monoxide and hydrogen. Opening and closing of the supply conduit valve in controlled sequences during out-of-normal operation of the gasification plant, particularly during periods of start-up and shut-down is accomplished by a permanently wired electric circuit initiated by an operator which causes an automatic performance of successive control actions.
