Process for the production of electricity in which a hydrocarbon stream 1 and an air stream 2 are reacted in a partial oxidation chamber 3, whereby the operating conditions are: -Dwell time in the chamber of between 100 and 1200 milliseconds - Output temperature of the chamber of between 1150 and 1650° C. Pressure of the chamber of between 0.1 and 1.5 MPa. The amount of soot contained in the effluent is less than 0.1% by weight relative to the feedstock. The effluent of the chamber is cooled, and it is circulated in a soot recovery zone that comprises a first circuit 6 comprising at least a first filter 7 and a second circuit 41 that are mounted in parallel, and during a period of time, a soot filtration stage of the effluent is carried out in the first filter which has a filtration surface area/useful volume ratio of between 80 and 5000 m 1. For another period of time, the first filter is regenerated in the presence of oxygen, and the cooled effluent is circulated in the second circuit. An effluent that is exiting from the hydrogen-rich recovery zone is recovered, and a fuel cell 10 of this effluent is fed.

Procédé de production d'électricité dans lequel on fait réagir un courant 1 d'hydrocarbures et un courant 2 d'air, dans une chambre 3 d'oxydation partielle, les conditions opératoires étant : - temps de résidence dans la chambre compris entre 100 et 1200 millisecondes - température de sortie de la chambre comprise entre 1150 et 1650°C - pression de la chambre comprise entre 0,1 et 1,5 MPa. La quantité de suies contenue dans l'effluent est inférieure à 0,1 %poids par rapport à la charge. On refroidit l'effluent de la chambre et on le fait circuler dans une zone de captation de suies comportant un premier circuit 6 comprenant au moins un premier filtre 7 et un deuxième circuit 41 qui sont montés en parallèle, on effectue pendant une période de temps, une étape de filtration des suies de l'effluent dans le premier filtre qui a un rapport surface de filtration sur volume utile compris entre 80 et 5000 m-1. Pendant une autre période de temps on régénère le premier filtre en présence d'oxygène, et on fait circuler l'effluent refroidi dans le second circuit. On récupère un effluent sortant de la zone de captation riche en hydrogène et on alimente une pile 10 à combustible en cet effluent.
