Abstract
Presented are one or more aspects and/or one or more embodiments of catalysts, methods of preparation of catalyst, methods of deoxygenation, and methods of fuel production.
Claims24
A method of producing fuel from oxygenated hydrocarbons, the method comprising:
- providing a catalyst comprising a porous substrate and an electrolessly deposited catalytically effective nanoscale metal coating on the substrate;
- contacting the catalyst with the oxygenated hydrocarbons and hydrogen so as to accomplish hydrogenation and deoxygenation wherein the deoxygenation is accomplished preferentially by decarbonylation and decarboxylation over hydrodeoxygenation to convert the oxygenated hydrocarbons into paraffinic wax product;
- and
- isomerizing and/or hydrocracking the paraffinic wax product to produce the fuel.

A method of producing fuel from oxygenated hydrocarbons, the method comprising:
- providing in a packed bed a catalyst comprising a porous substrate and an electrolessly deposited catalytically effective nanoscale metal coating on the substrate;
- contacting the catalyst with an upflow of the oxygenated hydrocarbons and hydrogen through the packed bed to accomplish hydrogenation and deoxygenation wherein the deoxygenation is accomplished preferentially by decarbonylation and decarboxylation over hydrodeoxygenation to convert the oxygenated hydrocarbons into paraffinic wax product;
- and
- isomerizing and/or hydrocracking the paraffinic wax product to produce the fuel.

A method of producing fuel, the method comprising:
- providing a catalyst in a deoxygenation reactor, the catalyst comprising a porous substrate and an electrolessly deposited catalytically effective nanoscale metal coating on the substrate;
- providing a feed of oxygenated hydrocarbons, a feed of hydrogen, and a recycle stream to the deoxygenation reactor so as to accomplish hydrogenation and deoxygenation wherein the deoxygenation is accomplished preferentially by decarbonylation and decarboxylation over hydrodeoxygenation to convert the oxygenated hydrocarbons into a paraffinic wax product;
- and
- isomerizing and/or hydrocracking the paraffinic wax product to produce the fuel.
