Two separate paraffinic hydrocarbon products, such as normal and monomethyl branched C10-C23 paraffins, are recovered from a mixture comprising the product hydrocarbons and many other hydrocarbons in a process employing two adsorptive separation zones in series. A single desorbent comprising a light paraffin is used in both zones and recovered in a single system, thus reducing capital and operating costs. The recovered paraffinic hydrocarbons may then be dehydrogenated and reacted with benzene to form alkylaromatic hydrocarbons useful as a detergent precursor.
