Abstract
This invention relates to a method of producing aromatics and olefins from oils derived from coal or wood, including partially saturating and cracking the oils derived from coal or wood in a hydrogenation and reaction area, separating them depending on the number of carbons, recirculating heavy oils having 11 or more carbons to the hydrogenation and reaction area, feeding oils suitable for producing BTX to an aromatic separation process and a transalkylation process to recover aromatics, and feeding hydrocarbonaceous components having 5 or less carbons to a light separation process, thus obtaining olefins.
