METHOD OF PREPARING BRANCHED ALKYL AROMATIC HYDROCARBONS USING COMBINED PROCESS STREAMS PRODUCED FROM HYDROGENATION, DEHYDROGENATION, DIMERIZATION AND ISOMERIZATION OF OLEFINS

摘要

SYSTEMS AND METHODS TO PRODUCE BRANCHED ALKYL AROMATIC HYDROCARBONS ARE DESCRIBED. SYSTEMS MAY INCLUDE A HYDROGENATION UNIT (110), A DEHYDROGENATION UNIT (114), AN OLEFIN DIMERIZATION UNIT (118), AN ISOMERIZATION UNIT (128), AN ALKYLATION UNIT (124) AND/OR ONE OR MORE SEPARATIONS UNIT. METHODS FOR PRODUCING A BRANCHED ALKYL AROMATIC HYDROCARBONS MAY INCLUDE ANY COMBINATION OF HYDROGENATION, DEHYDROGENATION, DIMERIZATION AND LOR ISOMERIZATION OF OLEFINS IN A PROCESS STREAM. THE PRODUCED OLEFINS MAY BE USED TO ALKYLATE AROMATIC HYDROCARBONS TO FORM BRANCHED ALKYL AROMATIC HYDROCARBONS. AFTER ALKYLATION OF THE AROMATIC HYDROCARBONS, UNREACTED COMPONENTS FROM THE ALKYLATION PROCESS MAY BE SEPARATED FROM THE ALKYL AROMATIC HYDROCARBONS. THE UNREACTED COMPONENTS FROM THE ALKYLATION PROCESS MAY BE RECYCLED BACK INTO THE MAIN PROCESS STREAM OR SENT TO OTHER PROCESSING UNITS.
