Abstract
Hydrocarbons are cracked in the presence of a mist of molten salt containing of basic compounds of alkali and alkaline earth metals and mixtures thereof, the amount of the molten salt to hydrocarbon being, by weight, from 0.01:1 to 10:1 followed by quenching at a temperature not lower than the melting point of the molten salt, and separating the cracked gas from the molten salt.
Claims7
A process which comprises cracking hydrocarbons in a cracking reaction zone in the presence of a mist of molten salt containing salt particles with an average particle size up to 300 microns, said salts being selected from the group consisting of basic compounds of alkali metals, alkaline earth metals and mixtures thereof, the weight ratio of molten salt to hydrocarbon being from 0.01:1 to 10:1, introducing the resulting cracked gas containing mist of molten salt into a means for quenching at a temperature not lower than the melting point of the molten salt, and separating the cracked gas and the molten salt from each other.
