Partial oxidation process
This patent describes a process for the partial oxidation of an ash-containing heavy liquid hydrocarbonaceous fuel, an ash-containing solid carbonaceous fuel, or mixtures thereof. It comprises: reacting the fuel with a free-oxygen containing gas and optionally with a temperature moderator to produce an effluent gas stream having a temperature in the range of about 2000{degrees} F. to 3000{degrees} F. and comprising H{sub 2} + CO and entrained molten slag; and cooling the effluent gas stream to a temperature in the range of about 350{degrees} F. to 1500{degrees} F. in a radiant or quench cooling zone located down-stream from the reaction zone. Wherein the molten slag is prevented from sticking to the internal metal surfaces of a gas transfer line or a gas transfer line and a convective cooler connected thereto and which surfaces are contacted by the partially cooled gas stream leaving the radiant or quench cooling zone by covering the metal surfaces of the gas transfer line or the gas transfer line and the convective cooler with a high temperature carbon-containing material.
