摘要:
A 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 comprises performing a partial oxidation on a hydrocarbon feed using a multi-orifice burner provided with an arrangement of separate co-annular passages, wherein the hydrocarbon flows through a passage of the burner, an oxidizer gas flows through a separate passage of the burner and wherein the passage for hydrocarbon feed and the passage for oxidizer gas are separated by a passage through which a moderator gas flows and wherein the exit velocity of the moderator gas is greater than the exit velocity of the oxidizer gas.
摘要:
Process, reactor and burner for the gasification of a hydrocarbon fuel. The burner comprises coaxial channels for the separate supply of an oxidizer gas, a hydrocarbon fuel and a moderator gas. A coaxial channel with the smallest width is bordered by a separating wall with at least one gas exchange. The gas exchange passage can for example be formed by a retracted end of the separating wall and/or by openings in the separating wall.
