A method for preparing a catalyst for use in the carbon monoxide shift reaction (a reaction wherein carbon monoxide and steam are reacted and converted to carbon dioxide and hydrogen) containing Pt as a primary active component, characterized in that use is made of a carrier comprising a metal oxide or composite metal oxide having a pore volume of 0.25 ml/g or more and a bulk density of 1 g/ml or less, and a Pt compound being free of a halogen and sulfur is used as the water-soluble precursor of Pt to be carried; and a catalyst prepared by the method. The catalyst can be activated with ease, is less susceptible to adverse effect by repeated stops and starts of operation or the incorporation of oxygen, and allows stable operation for a long period of time.

La présente invention concerne un procédé de préparation d'un catalyseur destiné à la conversion de monoxyde de carbone (une réaction dans laquelle le monoxyde de carbone et la vapeur réagissent et sont transformés en dioxyde de carbone et en hydrogène) contenant Pt comme composant actif principal. Ce procédé consiste à utiliser un porteur comprenant un oxyde métallique ou un oxyde de métal composite possédant une porosité d'au moins 0,25 ml/g et un poids volumétrique de 1g/ml au maximum, un composé Pt exempt d'halogène et on utilise du soufre comme précurseur soluble dans l'eau du Pt à porter. Cette invention concerne aussi un catalyseur préparé par ce procédé. On peut facilement activer ce catalyseur et ce dernier est moins susceptible de rencontrer les inconvénients causés par les arrêts et les démarrages répétés de fonctionnement ou par l'incorporation d'oxygène. Enfin il permet un fonctionnement stable pendant une longue durée.
