A novel process for the production and separation of heavier hydrocarbons from sorbitol-derived oil was studied. 2-Iodohexane, the by-product of the reduction of sorbitol into hydrocarbons, was successfully removed by transforming it into hexane and hexenes after reacting with zinc. The eliminating reaction was completed in 45 min at the conditions of: a zinc/2-iodohexane molar ratio of 6: 1, a reaction temperature of 120 degrees C, and an agitation speed of 1200 rpm. The heavier hydrocarbons obtained were mainly C-12 and C-18 alkanes, alkenes, and aromatics, which have a water content of 0.1% and a high heating value of 43.5 MJ/kg. Other physico-chemical properties of the heavier hydrocarbons were characterized with GC-MS, FT-IR and H-1 NMR. The approach developed in this work for the production and purification of heavier hydrocarbons from sorbitol-derived oil is relatively simple yet promising, which we believe could possibly become a new way for the production of transportation fuels from biomass sources.
