Abstract
The present invention provides for a low pressure, low temperature process for the production of middle distillate products, including aviation fuel and diesel, from the hydrocracking of a hydrocarbon feedstock consisting of a mixture of hydrocarbons, wherein a significant fraction of said mixture is C25+ hydrocarbons including hydrocarbons selected from Fischer-Tropsch wax, long chain paraffin and/or olefin, wherein the feedstock may include a water component.
Claims12
A process for the production of a middle distillate from a paraffinic hydrocarbon feedstock, the method comprising feeding the hydrocarbon feedstock into a hydrocracking reactor and over a metal loaded large pore zeolite catalyst having a SiO2/Al2O3 ratio of from about 2 to about 200 contained in the reactor wherein the metal is a noble metal selected from the group consisting of platinum, palladium, ruthenium, rhodium, osmium, and iridium, wherein a significant fraction of the feedstock is C25+ hydrocarbons, characterized in that the process is performed at a temperature of about 260° C. or less, and a pressure of about atmospheric pressure.
