Abstract: In the preparation of olefines, particularly ethylene and propylene, by the high-temperature cracking of hydrocarbons the gaseous reaction stream is quenched by supplying laterally to the stream one or more compact jets of liquid in an amount sufficient to cool the gas by at least 100 DEG C. and with a pressure head such that the liquid penetrates the gas and is disintegrated therein. Cracking may be effected in the presence of a fluidized solid, at 650-850 DEG C., and 1-5 atmospheres, e.g. in reactor 1, to which oxygen is also supplied. Solids are removed from the product stream by cyclone 2 from which the gaseous product leaves by pipe 4. Jets of liquid, e.g. liquid reaction products boiling below 300 DEG C., are injected into the gas from jets 6. Preferably the product of (a) the ratio of the pressure head of liquid to that of the gas (measured at the point of entry to the cooling chamber) and (b) the ratio of the mean diameter of the liquid jet to that of the gas, should lie in the range 0.01 to 3. Where several jets are used such products may differ for each jet and the jets may be in different planes. The walls of the cooling chamber are preferably washed with the cooling liquid, e.g. from atomizer 7. Products leave by line 8.
