A carbon monoxide removing catalyst such as a ruthenium supporting catalyst is provided for removing, through oxidation thereof, carbon monoxide from an alcohol reformed gas containing hydrogen and carbon monoxide to be supplied to a fuel cell. For its activation, the catalyst is caused to contact an inactive gas or a hydrogen-containing inactive gas consisting of less than 50 volume % of hydrogen gas and the remaining volume of inactive gas, thereby to avoid poisoning of the electrode of the fuel cell with carbon monoxide.

The present invention relates to a process for the catalytic reduction of nitrogen oxides contained in exhaust gases from combustion, which process comprises bringing said exhaust gases into contact with a Beta Zeolite exchanged with suitable amounts of cobalt salts, in the presence of a light hydrocarbon as the reducing agent. The present invention relates also to a catalyst for such a process, which catalyst comprises a Beta Zeolite exchanged with cobalt salts, characterized by a Co:zeolite Al molar ratio of &lt;0.5.

Process and catalyst for reducing NO.sub.x in exhaust combustion gases

A method for the desulfurization of hydrocarbons by desulfurizing unsaturated hydrocarbons or hydrocarbon materials containing unsaturated hydrocarbons, in the presence or absence of hydrogen, using a copper-zinc desulfurizing agent prepared by the co-precipitation method. By this method, the sulfur content of the hydrocarbons can be reduced while suppressing hydrogenation of the unsaturated hydrocarbons.
