Abstract

Acetylene is produced by the reaction of hydrocarbons with oxygen in which the reactants are separately preheated, mixed and supplied to a reaction chamber, wherein upon the occurrence of a flame or a premature reaction within the mixing apparatus, an inert gas or vapour is supplied for a short time. The inert gas which may be nitrogen, steam or carbon dioxide, is preferably automatically supplied to the oxygen current on the occurrence of a flame. In an example, 1800 cu. metres of methane per hour and 1050 cu. metres of oxygen per hour are preheated and then heated to 600 DEG C. After mixing, the gases are reacted with flame formation to produce a gas containing 8.5 per cent of acetylene. If the mixture ignites in the mixing chamber, about 250 litres of nitrogen is injected into the oxygen supply in the course of about 2 seconds and the flame extinguished. Specification 767,369 is referred to.ALSO:Hydrogen is produced by the reaction of hydrocarbons with oxygen in which the reactants are separately preheated, mixed and supplied to a reaction chamber, wherein upon the occurrence of a flame or a premature reaction within the mixing apparatus, an inert gas or vapour is supplied for a short time. The inert gas which may be nitrogen, steam or carbon dioxide, is preferably automatically supplied to the oxygen current on the occurrence of a flame. In an example, 250 cu. metres of coke oven gas (30 per cent methane) saturated with steam at 70 DEG C. and 46 cu. metres of oxygen saturated with steam at 70 DEG C. are fed to preheaters per hour. Then the gases pass at 600 DEG C. over a catalyst prepared by soaking magnesite with an aqueous solution of nickel nitrate to produce 400 cu. metres of synthesis gas containing 68 per cent of hydrogen. If a premature reaction takes place, a thermocouple automatically operates a valve which injects steam with the oxygen feed and extinguishes the flame in less than 5 seconds. Specification 767,369, [Group IV (b)], is referred to.
