Title:
A PROCESS FOR CATALYTIC, SELECTIVE OXIDATION OF CARBON MONOXIDE IN GASEOUS MIXTURES CONTAINING EXCESS HYDROGEN, A CATALYST AND A PROCESS FOR ITS PREPARATION
Document Type and Number:
WIPO Patent Application WO2001060738
Kind Code:
A3
Abstract:
The invention refers to a process for catalytic, selective oxidation of carbon monoxide in gaseous mixtures containing excess hydrogen with stoichiometric quantity of oxygen at the temperature between 298 K and 573 K, pressure between 1 and 10 bar and at the ratio of oxygen and carbon monoxide partial pressures ( lambda = 2p02/pco) between 1.0 and 2.5, in a one-step flow reactor at contact time (W/F) between 0.03 and 0.40 g.s.cm<-3>, or at the flow rate of the gaseous mixture (F) between 0.083 cm<3>/s and 1.67 cm<3>/s in the presence of 0.010 to 0.100 g of the catalyst, namely the complex oxide of the formula CuxCe1-xxO2-y, where x is between 0.01 and 0.30 while y is equal or greater than x. This invention refers also to a process for the catalyst preparation and to the catalyst prepared by this process. This invention is useful in the field of fuel technology for low temperature fuel cells.
