International Classification:

B05B 700

US Classification:

2391323

Abstract:

A partial oxidation process and a novel burner are provided for simultaneously introducing two or three separate feedstreams into a free-flow partial oxidation gas generator for the production of synthesis gas and fuel gas, or reducing gas. The reactant feedstreams include a liquid hydrocarbonaceous fuel or a pumpable slurry of solid carbonaceous fuel, and a free-oxygen containing gas e. g. air or oxygen. The burner comprises a central conduit and a plurality of spaced concentric coaxial conduits with down-flowing annular passages. A flat annular-shaped disc or cup-shaped porous ceramic or porous metal cooling means of uniform composition, wall thickness and porosity with the various pores interconnecting is attached to the downstream tip of the burner. A controlled amount of liquid coolant under pressure is passed successively through the porous inside surface, porous core and porous outside surface of the cooling means is vaporized. The tip of the burner is thereby cooled.

International Classification:

C01B 700
C07C 102

US Classification:

423240R

Abstract:

The present invention relates to a method for minimizing hydrogen halide corrosion in quench gasifier during the non-catalytic partial oxidation reaction of a halogen-containing hydrocarbonaceous feed, to produce a hydrogen halide-containing synthesis gas, finely divided particulate solids, and a nontoxic slag. The hydrogen halide-containing synthesis gas is contacted with water in the quench zone of the gasifier. The quench water contains a neutralizing agent, in excess of the amount necessary to neutralize hydrogen halide acids present therein, to thereby form halide salts. The quench water containing the halide salts is purified to recover the halide salts. The salt-free water is essentially environmentally non-toxic and can either be recycled to the process or discarded in conformity with environmental regulations.

International Classification:

C07C1/02

US Classification:

252373

Abstract:

An integrated liquefaction and gasification process converts bulk particulate halogen-containing waste plastic materials with minimal particle size reduction into a synthesis gas and a non-leachable, vitreous environmentally nontoxic slag. The process involves melting and cracking bulk particulate halogen-containing waste plastic material to form a lower boiling point, lower molecular weight halogen-containing oil composition which then undergoes partial oxidation in a quench gasifier to produce a synthesis gas. Any hazardous gases, liquids or solids that are produced can be purified into commercially valuable byproducts or recycled to the process, which does not release hazardous materials to the environment.

International Classification:

C22B 704

US Classification:

48197R

Abstract:

A method is disclosed for recovering condensed solidified volatile metals from the slag that exits the reactor section of a partial oxidation reactor. In a partial oxidation reactor, condensed solidified volatile metals become adsorbed to the surface of the slag particles and other particulate matter associated with the gasification reaction, such as ash and soot. These particulate materials can be removed and recovered. Finely divided slag particles can be separated and contacted with a mineral acid to dissolve the adsorbed condensed volatile metals. An acid liquor results which contains dissolved volatile metal salts of the acid. The acid liquor containing the dissolved volatile metal acid salts is then electrolyzed to reduce the dissolved volatile metal acid salts to the corresponding elemental metal for recovery.

International Classification:

C01B 322
C01B 324

US Classification:

252373

Abstract:

Slag deposits in partial oxidation reactors, like coke gasifiers, are removed by controlling temperature and slag derivatization. Derivatized slag is fluidized and leaves the reactor without solidifying in and filling the reactor outlet.

International Classification:

F23C 110

US Classification:

110261

Abstract:

An improved burner for partial oxidation process gas generators is provided which has annular passages formed between coaxially aligned conduits extending from upstream sources to the downstream reaction zone. An outer coolant jacket, internally baffled from optimum coolant flow and sized for minimum downstream area surrounds a recessed and fuel/oxidizer delivery conduit ending in a nozzle. The central delivery conduit is not attached to the coolant jacket and the annular space between them is connected to a high pressure supply of relatively inert gas which can periodically be vented through the annular space to prevent slag build up on the nozzle or coolant jacket.
