    摘要： 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 copper-containing additive; and (iii) at least a portion of the remainder of the copper-containing slag after separation of an enriched vanadium-containing coarse slag fraction. Materials (ii) and (iii) combine in the partial oxidation reaction zone with at least a portion of the nickel and iron constituents and the sulfur found in the feedstock to produce a liquid phase washing agent that collect and transports at least a portion of the vanadium-containing oxide laths and spinels and other ash components out of the reaction zone as molten vanadium-containing slag. A coarse slag fraction having a decreased Cu/V weight ratio is produced when a portion of the molten slag entrained in the hot raw effluent gas stream from the partial oxidation reaction zone is deposited 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. Chunks of the slag drop into the quench tank and the enriched vanadium containing coarse slag portion is separated from the remainder of the copper-containing slag comprising smaller sized particles. It is economically advantageous to recover by-product vanadium from the coarse slag fraction in a metal refining plant.

    摘要： A partial oxidation process for the production of a stream of mixed gases comprising H.sub.2 and CO. An aqueous particulate solid carbonaceous fuel slurry feedstream is preheated by indirect heat exchange with a process-derived stream of skimmed gases substantially comprising H.sub.2 O. The aqueous carrier of the slurry is vaporized by introducing superheated steam directly into the slurry pipeline. A suspension of particulate solid carbonaceous fuel entrained in a gaseous mixture substantially comprising steam e.g. about 90 to 99.9 wt. % H.sub.2 O and about 0.1 to 10 wt. % of a CO.sub.2 -containing gas mixture is produced. The suspension of solid fuel in the gaseous mixture is then separated in a skimming operation into an overhead gas stream substantially comprising steam, as previously described, and a bottom stream comprising particulate solid carbonaceous fuel with the remainder of said gaseous mixture. The bottom stream from the skimming operation is introduced into the reaction zone of a partial oxidation gas generator in admixture with a free-oxygen containing gas and with or without a temperature moderator where a gaseous stream comprising H.sub.2 +CO is produced. In one embodiment, the temperature of the suspension of solid carbonaceous fuel feed stream entering the partial oxidation reaction zone by way of a burner is monitored. An increase in temperature would flag the back-flow of synthesis gas or oxygen into the burner. When this happens, the feedlines to the burner and the overhead gas stream from the cyclone separator may be automatically shut down to prevent thermal damage to the system.

    摘要： A feeder for finely divided solids from atmospheric pressure into a high pressure atmosphere. It has a chute to hold the solids at atmospheric pressure, and a valve with seals to deliver the solids into a loading chamber. There is an arrangement for pressurizing the loading chamber, and the chamber is oriented so that the solids will discharge through another valve by gravity flow into the high pressure atmosphere after pressurization of the chamber. There is also an arrangement for displacing the high pressure atmosphere from the chamber after discharge of the solids and before the next delivery of another charge from the chute.

    摘要： A method is provided for turning down or up the output of raw product gas from a partial oxidation gas generator while maintaining in an acceptable range the efficiency of the gas generation, or conversion of the fuel to gas, and the quality of the gas produced. In the process, the flow rates for the separate feedstreams to the burner comprising fuel optionally in admixture with a temperature moderator, at least one stream of free-oxygen containing gas optionally in admixture with a temperature moderator, and with or without a separate feedstream of temperature moderator are adjusted down or up a predetermined amount to obtain a specified output of raw product gas while maintaining substantially constant in the reaction zone the levels of O/C atomic ratio and the temperature moderator/fuel weight ratio. Further, the temperature of at least one stream of free-oxygen containing gas optionally in admixture with a temperature moderator is increased at turn-down and decreased at turn-up to a predetermined value which is an indirect function of its adjusted flow rate. By this means, the burner tip velocity of the temperature adjusted stream of free-oxygen containing gas optionally in admixture with a temperature moderator is held within an acceptable range, and changes in the process efficiency and pressure drop across the burner are minimized.
