Abstract: One exemplary embodiment can be a process for hydroprocessing. The process can include providing a hydroprocessing zone having at least two beds, and quenching downstream of a first bed of the at least two beds with a first vacuum gas oil that may be lighter than another vacuum gas oil fed to the first bed.

Abstract: A process and apparatus for reducing the sulfur content of naphtha. The process includes introducing at least a portion of a naphtha feed stream to a selective hydrodesulfurization zone under selective hydrodesulfurization conditions in the presence of a selective hydrodesulfurization catalyst to form a low sulfur stream which contains mercaptan and thiophene compounds. At least a portion of the low sulfur stream is separated into at least two streams, a mercaptan rich stream containing mercaptan and thiophene compounds and an overhead stream containing hydrogen sulfide and liquid petroleum gas. The mercaptan rich stream is treated in an adsorbent zone to remove at least a portion of the mercaptan and thiophene compounds to form a mercaptan lean stream.

Abstract: Processes for the production of transportation fuel from a renewable feedstock. A catalyst is used which is more selective to hydrodeoxygenate the fatty acid side chains compared to decarboxylation and decarbonylation reactions. A gaseous mixture of carbon monoxide and hydrogen can be supplied to the conversion zone. Water may also be introduced into the conversion zone to increase the amount of hydrogen.

Abstract: The process and apparatus of the present invention selectively hydrogenates a heavier olefinic naphtha stream in an upstream catalyst bed and the hydrogenated effluent and a lighter olefinic naphtha stream in a downstream catalyst bed. The heavier di-alkenes are less re-active and are contacted with more hydrogenation catalyst than the lighter di-alkenes which are more re-active.

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.
