Abstract
A method of converting a liquid hydrocarbon stream to lower boiling point hydrocarbons may include converting the liquid hydrocarbon stream to an aerosolized hydrocarbon particle stream, and subjecting the aerosolized hydrocarbon particle stream to reaction conditions. Reaction conditions may include a temperature from 25° C. to 1,000° C. and a pressure from 1 bar to 15 bar. The method may further include forming the lower boiling point hydrocarbons in the aerosolized hydrocarbon particle stream and separating the lower boiling point hydrocarbons from the aerosolized hydrocarbon particle stream. The lower boiling point hydrocarbons may comprise at least C2—C4 olefins.
