Abstract: The process takes place in a kiln, the combustion assembly of which has parallel channels. Through them at the starting-material, subsequent to pre-heating and pre-mixing, is passed into the combustion chamber. The channels narrow conically towards the outlet aperture(s) esp. at an angle 6-20 degrees.

Abstract: In the production of acetylene by subjecting hydrocarbons to high temperatures, the hot gas is quenched in a single stage by injecting a hydrocarbon oil boiling above 150 DEG C. in a volume ratio to gas (measured under standard conditions) of at least 1 : 100 without any appreciable cracking of the oil and separating the hot oil containing carbon black from the gas. The oil is preferably an aromatic oil and useful heat is extracted from it before its reuse; the carbon black content is preferably reduced to below 35% by weight e.g. by removing part of the oil and replacing this by fresh oil. The gas is preferably also later washed with an oil boiling in the range 80-450 DEG C. having a specific gravity below 0.95. The examples relate to the partial combustion of gasoline and of methane; reference is also made to heating hydrocarbons by electric discharge and exposure to hot flame gases. Specification 893,504 is referred to.
