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.
Claims22
A method of making a catalyst, the method comprising:
- providing a granular or pelletized porous substrate;
- providing a solution comprising ions of a metal for electroless deposition;
- mixing the substrate with the solution;
- 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.

A method of making a catalyst, the method comprising:
- providing a substrate comprising granular activated carbon;
- exposing the substrate to a tin chloride solution so as to sensitize the activated carbon for electroless deposition;
- exposing the substrate to a palladium chloride solution so as to activate the activated carbon for electroless deposition;
- providing a solution of palladium for electroless deposition;
- mixing the substrate with the solution;
- 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 hydrazine incrementally or continuously so as to cause controlled electroless deposition of the palladium as a catalytically active nanoscale coating of the activated carbon.
