Abstract: Hydrocarbon composition plays vital role in fuel quality. For gasoline/motor spirit applications the hydrocarbon should have more octane-possessing molecules from the groups of aromatics, naphthenics and isoparaffins, while n-paraffins are not preferred due to their poor octane. Among the high-octane groups, again aromatics occupy the top but not more than 35 vol % aromatics can be mixed in gasoline for engine applications to avoid harmful emission, But there is no single process that addresses so far the issue of co-producing all the desired hydrocarbon components in a single process. Thus, it is interesting to have a single once-through process working on single catalyst system to produce mixture of all three high-octane molecules namely, aromatics, naphthenics and isoparaffins directly from low-value, low-octane n-paraffin feed. Herein, we report a novel single-step catalytic process for the simultaneous production of aromatics, naphthenics and isoparaffins for gasoline and petrochemical applications.

Abstract: Processes for the production of transportation fuel from a renewable feedstock. A gaseous mixture of carbon monoxide and hydrogen is used to deoxygenate and hydrogenate the glycerides to produce long chain hydrocarbons. The hydrocarbons may be isomerized to improve cold flow properties to provide a diesel fuel. Prior to isomerization, the long chain hydrocarbons can be separated or the separation can be after isomerization. Recycle gas streams from the isomerization and the deoxygenation and hydrogenation reactions may be used to supply at least a portion of the gaseous mixture of carbon monoxide and hydrogen. Synthesis gas may also be used to supply at least a portion of the gaseous mixture of carbon monoxide and hydrogen.
