Integrated processes for making detergent range alkylbenzenes from C5-C6-containing feeds

An integrated process for producing detergent range alkylbenzenes from a feedstock predominantly comprising C5 and C6 paraffins, the process comprising:

• a) subjecting the feedstock to an oxygenate extraction process, thereby creating a feedstock with a reduced oxygenate content;
• b) subjecting the feedstock with a reduced oxygenate content to dehydrogenation conditions to provide a dehydrogenated product that comprises C5 and C6 mono-olefins, benzene, and a minor amount of dienes;
• c) reacting at least a portion of the dehydrogenated product of step a under dimerization or metathesis condition to provide a detergent range olefin product comprising C10 to C12 mono-olefins;
• d) selectively hydrogenating at least a portion of at least one of the feedstock, the dehydrogenated product of step a, and the detergent range olefin product of step b at selective hydrogenation conditions to reduce diene concentration;
• e) alkylating benzene with at least a portion of the detergent range olefin product under alkylation conditions including a stoichiometric excess of benzene to olefin to provide an alkylation effluent comprising alkylbenzenes and benzene, wherein a portion of the benzene is passed in with the detergent range olefin product;
• and
• f) separating benzene from at least a portion of the alkylation effluent and recycling at least a portion of the separated benzene to step e;
• wherein the detergent range olefin product of step c contains aromatic compounds and at least a portion of the detergent range olefin product is contacted with a sorbent to selectively sorb the non-benzene aromatic compounds and provide the detergent range olefin product having a reduced aromatic compound concentration.
