摘要： The present invention is an integrated process and apparatus for supplying at least a portion of the reducing gas feedstock to a reduction reactor, such as a reactor for the direct reduction of iron, wherein the reducing gas contacts a feed material at a mean operating gas pressure and effects reduction of the feed material to provide a reduced product. The integrated process includes gasifying a hydrocarbonaceous feedstock in a partial oxidation reaction to produce a synthesis gas which comprises hydrogen, and carbon monoxide at a pressure substantially greater than the mean operating gas pressure in the reduction reactor. The synthesis gas is expanded to lower its pressure to substantially the mean operating gas pressure in the DRI reduction reactor to thereby form the reducing gas feedstock at the pressure conditions used for the DRI reaction. The lower pressure reducing gas mixture generated by the expansion is introduced into the DRI reactor as part or all of the reducing gas requirement for the direct reduction of iron.

摘要： A method of operating a diesel or spark ignition engine which includes enriching the combustion air supply with oxygen while simultaneously adjusting the fuel injection or ignition timing of the engine to compensate for advanced combustion caused by an increased oxygen content in the conbustion air. Oxygen producing means such as an oxygen generating membrane can eliminate the requirement for, or significantly reduce the size of, an intercooler which is normally installed between a turbocharger and the air/fuel inlet of an engine. Oxygen enrichment of the combustion air permits combustion of otherwise unsuitable or difficult to combust fuels such as residual or heavy fuel oils, alcohol and alcohol blends, seed oil and blends of light gas oils and residual or heavy fuel oils.

摘要： This specification discloses a greatly simplified method and system for recovering coal from a particulate coal bearing slurry (1) in which an appropriate hydrophobic liquid or emulsion of hydrophobic liquid in water (2) is introduced into the inlet of a centrifugal turbulent flow slurry pump (3) simultaneously with the introduction of said coal bearing slurry to said pump inlet, said hydrophobic liquid being introduced in a quantity sufficient to achieve substantially intimate contact between said hydrophobic liquid and coal particles in said slurry whereby the coal may be separated from the slurry by discharging the slurry from the pump directly over a simple static screen or other suitable separating device (4) whereupon the separated coal matter (5) may be collected for subsequent use. If desired, the coal within said slurry may be additionally agitated in any suitable manner, such as by means of an in-line flow promoting device (7) which causes additional contact between the agglomerates produced by the agitation achieved within the slurry pump (3).
