Abstract
Description
Technical field
[0001] The present invention relates to a method for increasing the yield of benzene prepared from a hydrocarbon mixture. More specifically, the present invention relates to a method for improving the yield of benzene by combining the process of preparing an aromatic hydrocarbon mixture and liquefied petroleum gas (LPG) from a hydrocarbon mixture with a solvent extraction process for separating and recovering polar hydrocarbons from the hydrocarbon mixture. Methods. Background technique
[0002] Generally, aromatic hydrocarbons are separated from non-aromatic hydrocarbons by solvent extraction method to separate raw material fractions rich in aromatic compounds (such as reformed oil made by catalytic reforming process and pyrolysis gasoline made by naphtha cracking process). obtain. The aromatic hydrocarbon mixture thus obtained is separated into benzene, toluene, xylene, and C9+ aromatic compounds according to different boiling points to be used as basic petroche...
