Method for producing valuable aromatics and light paraffins from hydrocarbonaceous petroleum oils, coal or wood

摘要

A method for producing aromatics and light paraffins, comprising: (a) introducing petroleum oils, coal or wood in a hydrogenation reaction zone so that polycyclic aromatic components are cracked and partially saturated; (B) separating the components obtained in step (a) in the form of hydrocarbonaceous components having 11 or more carbon atoms, hydrocarbonaceous components having 6 ~ 10 carbon atoms and hydrocarbonaceous components having 5 or less carbon atoms; and (c) recirculating the hydrocarbonaceous components having 11 or more separate carbon atoms in steps b) to (a) feeding the hydrocarbonaceous components having 6 ~ 10 carbon atoms to a method of separating aromatic compounds and a method transalkylation recovers so that at least a portion of the aromatic compounds, and feeding the hydrocarbonaceous components having 5 or less carbon atoms to a process for separation of light products, thus obtaining paraffins.
