Beschreibung
Zusammenfassung:	The present invention relates to a method for the desulfurization of a fossil fuel containing one or more organosulfur compounds. In one embodiment, the method comprises the steps of (1) contacting the fossil fuel with a biocatalyst capable of converting the organosulfur compound to an oxyorganosulfur compound which is separable from the fossil fuel; and (2) separating the oxyorganosulfur compound from the fossil fuel. The oxyorganosulfur compound can then be isolated, discarded or further processed, for example, via desulfurization by a biocatalyzed process or an abiotic process, such as hydrodesulfurization. L'invention concerne un procédé servant à désulfurer un combustible fossile contenant un ou plusieurs composés d'organosulfure. Dans un mode de réalisation, ce procédé consiste à (1) mettre en contact le combustible fossile avec un biocatalyseur capable de convertir le composé d'organosulfure en un composé d'oxyorganosulfure pouvant être séparé du combustible fossile et (2) à séparer ce composé d'oxyorganosulfure du combustible fossile. On peut ensuite isoler, rejeter ou continuer à traiter ce composé d'oxyorganosulfure, par exemple, par désulfuration au moyen d'un procédé biocatalytique ou abiotique, tel qu'un procédé d'hydrodésulfuration.
