Abstract
A catalyst comprising a physical mixture of particles of a catalytic material and particles of char is provided. The catalyst can be used in various processes, including the reforming of tars present in syngas generated during biomass gasification. The catalyst is produced through a mechanical mixing of the catalytic material and char particles, which results in significant time and energy savings over methods of catalyst preparation that involve impregnation and calcining of a support material.
Claims12
A method of removing tars from a syngas stream and conditioning said syngas stream comprising the steps of:
- providing a catalyst comprising a dry, uncalcined physical mixture of discrete particles of a catalytic material and char, wherein said char is not impregnated with said catalytic material;
- contacting a syngas-containing stream having tars present therein with said catalyst under conditions for converting at least a portion of the tars into syngas components.
A system for removing tars from a syngas stream and conditioning said syngas stream comprising:
- a reactor vessel comprising a quantity of a catalyst comprising a dry, uncalcined physical mixture of discrete particles of a catalytic material and char, wherein said char is not impregnated with said catalytic material;
- and
- a source of syngas operably connected with said reactor vessel, said syngas having tars present therein.
