48285790, May 9, 1989

Filed:

Mar 7, 1988

Appl. No.:

7/164750

Inventors:

Michael W. Becker - Westminster CA
Allen M. Robin - Montebello CA
John S. Stevenson - Montebello CA

International Classification:

C10J 348

US Classification:

48 69

Abstract:

Reactor for gasifying a carbonaceous fuel to produce a usable gas, and comprising an insulated outer shell. A reaction chamber within the shell receives a fuel mixture from an injection burner. The products or effluent of gasification include hot produced gases which are passed through a constricted throat to be cooled in a liquid bath. A dip tube, which guides the hot effluent into the bath, is provided with a stream of coolant from a quench ring. The latter is supported below the reaction chamber and is provided with a thermal barrier along its surface that is exposed to the hot produced gas. The barrier will reduce thermal stress in the quench ring and reduce drain of heat from the gasifier throat, thus avoiding premature chilling of the slag component.

Abstract:

Process for the production of gaseous mixtures comprising H. sub. 2 +CO e. g. synthesis gas, reducing gas, or fuel gas by the partial oxidation of a vanadium-containing liquid hydrocarbonaceous fuel, solid carbonaceous fuel, or mixtures thereof in a free-flow vertical refractory lined gas generator. The feed mixture to the gas generator comprises (i) a vanadium-containing fuel; (ii) supplemental iron-containing ash fusion temperature reducing agent; and (iii) at least a portion of the remainder of the iron-containing slag after separation of an enriched vanadium-containing coarse slag fraction. The coarse slag fraction has a decreased Fe/V weight ratio and is formed by depositing a portion of the slag entrained in the hot raw effluent gas stream from the partial oxidation reaction zone on the walls of a slag separation chamber located between the bottom discharge outlet in the reaction zone and the effluent gas quench tank located at the bottom of the gas generator. It is economically advantageous to recover by-product vanadium from the coarse slag fraction in a metal refining plant.
