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 catalyst comprising:
- a granular or pelletized porous substrate;
- and
- a metal coating formed on the substrate by mixing the substrate with a solution comprising ions of the metal for electroless deposition and controlling the temperature of the mixture of the substrate and the solution to ramp from a first temperature to a higher temperature while adding a reducing agent incrementally or continuously so as to cause electroless deposition of the metal on the substrate.
A catalyst for deoxygenating bio-oils for fuel production, the catalyst comprising:
- a substrate comprising activated carbon in granular or pelletized form with size in the range of 0.5 mm to 3 mm having pores 0.2 nm to 10 nm wide;
- and
- an electrolessly deposited catalytically effective palladium or nickel coating having nanoscale thickness disposed on the surfaces of the pores, the palladium or nickel loading being less than about 2% by weight, the palladium or nickel coating formed on the substrate by mixing the substrate with a solution comprising ions of the palladium or nickel for electroless deposition and controlling the temperature of the mixture of the substrate and the solution to ramp from a first temperature to a higher temperature while adding a reducing agent incrementally or continuously so as to cause electroless deposition of the palladium or nickel on the substrate;
- the catalyst being catalytically effective for hydrogenation and deoxygenation wherein the deoxygenation is preferentially by decarbonylation and decarboxylation over hydrodeoxygenation.

A catalyst comprising:
- a granular or pelletized porous substrate;
- and
- a metal coating formed on the substrate by mixing the substrate with a solution comprising ions of the metal for electroless deposition and controlling the temperature of the mixture of the substrate and the solution to ramp from a first temperature to a higher temperature while adding a reducing agent incrementally or continuously so as to cause controlled electroless deposition of the metal as a catalytically active nanoscale coating of the substrate.
