Particulate compositions are described comprising an intimate mixture of a coal and a gasification catalyst in the presence of steam to yield a plurality of gases including methane and at least one or more of hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and other higher hydrocarbons are formed. Processes are also provided for the preparation of the particulate compositions and converting the particulate composition into a plurality of gaseous products. L'invention concerne des compositions particulaires qui comprennent un mélange intime de charbon et d'un catalyseur de gazéification en présence de vapeur pour obtenir une pluralité de gaz, y compris du méthane. Selon l'invention, de l'hydrogène et/ou du monoxyde de carbone et/ou du dioxyde de carbone et/ou du sulfure d'hydrogène et/ou de l'ammoniac et/ou d'autres hydrocarbures supérieurs sont formés. L'invention concerne également des procédés de préparation des compositions particulaires et de conversion de la composition particulaire en une pluralité de produits gazeux.
