CA 2670795

Process to prepare a synthesis gas mixture comprising hydrogen and carbon monoxide from a liquid hydrocarbon feedstock containing between 0.1 and 4 wt% ash by performing a partial oxidation on a hydrocarbon feed (4) using a multi-orifice burner (2) provided with an arrangement of separate co-annular passages, wherein the hydrocarbon flows through a passage of the burner, an oxidiser gas (3) flows through a separate passage of the burner and wherein the passage for hydrocarbon feed and the passage for oxidiser gas are separated by a passage through which a moderator gas (5) flows and wherein the exit velocity of the moderator gas is greater than the exit velocity of the oxidiser gas.

L'invention concerne un procédé de préparation d'un mélange de gaz de synthèse comprenant de l'hydrogène et du monoxyde de carbone à partir d'un stock d'alimentation d'hydrocarbure liquide contenant entre 0,1 et 4 % en poids de cendres en réalisant une oxydation partielle sur une alimentation en hydrocarbure en utilisant un brûleur à orifices multiples doté d'une disposition de passages co-annulaires séparés. L'hydrocarbure s'écoule dans un passage du brûleur et un gaz oxydant s'écoule par un passage séparé du brûleur. Le passage pour l'alimentation en hydrocarbure et le passage pour le gaz oxydant sont séparés par un passage dans lequel s'écoule un gaz modérateur, la vélocité de sortie du gaz modérateur étant supérieure à la vélocité de sortie du gaz oxydant.
