METHOD FOR PYROLYSIS OF HYDROCARBON FEEDSTOCK CONTAINING ETHANE AND LIQUEFIED HYDROCARBONS Russian patent published in 2022 - IPC C10G9/00 C10G45/26 

FIELD: hydrocarbons pyrolysis methods.

SUBSTANCE: invention relates to methods for the pyrolysis of hydrocarbons. A method for pyrolysis of hydrocarbon feedstock containing ethane and liquefied hydrocarbons is described, where the hydrocarbon feedstock is prepared by mixing ethane and liquefied hydrocarbon streams heated to a temperature of 60-150°C, with the content of liquefied hydrocarbons in the hydrocarbon feedstock from 5 to 30 wt.%, served for pyrolysis in the presence of water vapor, while propane, butane or their mixtures are used as liquefied hydrocarbons.

EFFECT: expansion of the arsenal of pyrolysis methods allowing to obtain ethylene in high yield.
