Abstract:
1. A method for producing aromatics and olefins from hydrocarbonaceous oils derived from coal or wood comprising: a) introducing oils derived from coal or wood comprising aromatic compounds into a hydrogenation and reaction area comprising a hydroprocessing process and a catalytic cracking process; b) hydroprocessing the oils in the presence of a hydroprocessing catalyst to partially saturate aromatic components having two or more aromatic rings into aromatic components having one aromatic ring, such that an amount of aromatic components having one aromatic ring in the oils is increased; c) catalytically cracking the hydroprocessed oils in the presence of a cracking catalyst to form catalytically cracked oils; d) separating the catalytically cracked oils into e) recirculating the hydrocarbonaceous components having 11 or more carbons to the hydrogenation and reaction area; f) feeding the hydrocarbonaceous components having 6-10 carbons to an aromatic separation process or a transalkylation process, g) feeding the hydrocarbonaceous components having 5 or less carbons to a light oil separation process to recover olefins;
