Abstract
Reactors and methods for reducing the carbon monoxide concentration in a reactant stream are provided. The reactors are generally configured such that the gas hourly space velocity of the reactors increases along a reactant flow path between inlets and outlets of the reactors. The reactors may have preferential oxidation catalysts disposed along a reactant flow path.
Claims24
A device comprising a reactor defined by a length, an inlet, and an outlet, wherein:
- said reactor comprises a reactant flow path between said inlet and said outlet;
- said reactor further comprises at least one preferential oxidation catalyst disposed along said length of said reactor;
- said reactant flow path is configured such that a reactant stream may flow along said length of said reactor from said inlet to said outlet;
- said reactant flow path is configured such that said reactant stream may contact said at least one preferential oxidation catalyst;
- and
- said reactant flow path is configured such that the gas hourly space velocity of said reactor increases along said reactant flow path between said inlet and said outlet.
