ABSTRACT:
This invention relates to a process for the production of aldehydes/alcohols and alkyl benzene. According to the invention, a hydrocarbon feed stream containing olefins and paraffins having an average number of carbon atoms from 10 to 18 per molecule, typically derived from the condensation product of a Fischer-Tropsch reaction is subjected to a hydroformylation reaction to provide a hydroformylation product containing aldehydes/alcohols and paraffins. An aldehyde/alcohol product is separated from the paraffins in the hydroformylation product to provide an aldehyde/alcohol product stream and a paraffin stream. The paraffin stream separated from the hydroformylation product is then subjected to a dehydrogenation reaction to form a dehydrogenation product containing olefins and paraffins, and the dehydrogenation product is subjected to an alkylation reaction to convert olefins to alkyl benzene.
