Abstract:
The present invention is directed to a process for converting heavy hydrocarbonaceous feeds to jet and diesel products: using a single reactor, dual catalyst system; or using a single reactor, multiple catalyst system.
Abstract:
The present invention is directed to an alumino-borosilicate SSZ-57 zeolite having enhanced large pore selectivity. The alumino-borosilicate SSZ-57 zeolite of the present invention is characterized as having substantially all of its aluminum atoms located within regions of the zeolite structure which form the 12 ring channels.
Abstract:
The present invention relates to a new process which comprises the steps of hydrotreating, paraffin disproportionation and hydroisomerization to convert biological hydrocarbonaceous oxygenated oils comprising triglycerides into biologically-derived paraffinic jet/diesel fuels, solvents and base oils. A combination of conventional hydrogenation/dehydrogenation catalysts, such as Pt/Al2O3, and conventional olefin metathesis catalysts, such as WO3/SiO2, or inexpensive variations thereof, is generally employed in the paraffin disproportionation step.

Abstract:
A hydroconversion process comprises contacting a feedstock comprising renewable materials under hydroprocessing conditions with a promoted catalyst selected from a self-supported catalyst, a supported catalyst and combinations thereof, wherein the reaction conditions can be tailored to directly convert the renewable feedstock to the desired product(s) including fatty alcohols, esters, normal paraffins, or combinations thereof. The catalyst comprising at least a Group VIB metal selected from molybdenum and tungsten, a Group VIII metal selected from cobalt and nickel to convert the feedstock into any of fatty alcohols, esters, and normal paraffins. In some embodiments, the process further comprising additional steps to generate various desirable products, including α-olefins (or PAO, by dehydrating the fatty alcohol products), lubricants and bright stocks (from the oligomerizing of the PAO), and Group 3 lubricants (from co-oligomerizing of the PAO with some short chain olefins).
Abstract:
A process for isomerizing light paraffins using a catalyst comprising an SFS-type zeolite and at least one Group VIII metal. It has been found that the catalyst can selectively convert C6 paraffins into the more favorable higher octane C6 isomer, namely 2,3-dimethylbutane (RON=105), over the less favorable C6 isomer, namely octane 2,2-dimethylbutane (RON=94).
Abstract:
A hydrocarbon conversion process comprises contacting a renewable feedstock under hydroprocessing conditions with a bulk catalyst to form oleochemicals such as fatty alcohols, esters, and normal paraffins. Advantageously, the reaction conditions can be selected to directly convert the renewable feedstock to the desired product(s).
