摘要:
A carbonaceous-based metallizing method and apparatus wherein a metallic oxide is converted into a carbon-containing, metallized intermediate that is melted in an induction channel furnace to produce liquid metal from said metallic oxide. In the application of iron ore in the form of fines or concentrate, using low-cost coal will greatly reduce capital and operating costs by virtue of eliminating agglomeration of ore, cokemaking, and blast furnace operation. The liquid iron so produced is efficiently converted into steel in a steelmaking furnace such as a basic oxygen furnace (BOF), especially when it is physically integrated to the induction channel furnace wherein the liquid iron is directly poured into the integrated BOF by the induction channel furnace, producing low-cost steel, little heat loss, and minimum emissions.

The present invention deals with the serious pollution problems from electric power plants that burn coal which may be forced to shut down by virtue of their being uneconomical to be retrofitted with expensive pollution controls. The pollutants from coal-burning power stations comprise SO2, NOx, Hg, Particulate Matter, Ash, and CO2. This invention offers a unique and comprehensive solution that makes possible the prevention of the ill-effects currently caused to health and environment while at the same time would also prevent the closure of these badly needed power generation facilities that provide some 50% of the electricity generated in this country. The herein comprehensive solution converts the six mentioned pollutants into valuable products and thus avoids the discharge of such pollutants into the atmosphere.
摘要:
A method and apparatus for gasifying a solid fuel within a pressurized gasifier without a lockhopper, a slurry or pulverization comprising the feeding of said fuel into a charging chamber having a first section equipped with a ram through which a mandrel is disposed, and a second section within which an impervious seal is formed from the solid fuel by the compressive forces generated by said ram and a third section into which the seal is advanced while said ram forms a successive seal in said second section. The seal from said third section is reduced in size and charged into the pressurized gasifier where it is gasified without loss of pressure. The gases produced are utilized to polygenerate products such as transport fuels and electric power, and a fertilizer from waste gas resulting from the combustion of one of the produced gases.

The present invention consists of an improved method and apparatus to upgrade bitumen in various forms which comprises four main components; namely, a fractionator equipped with a condenser, a heavy gas oil catalytic treater, a catalyst regenerator/gasifier and a gas cleanup assembly. In operation, the bitumen in liquid form is fed to the fractionator for initial separation of fractions with the bulk of the bitumen leaving the bottom of the fractionator in the form of a heavy gas oil which is pumped to the catalytic treater and sprayed on a hot catalyst to crack the heavy gas oil (an endothermic reaction) to release lighter hydrocarbons in the form of H2 rich volatile matter while depositing carbon on the catalyst. The volatile matter from the treater is directed to the fractionator where the condensable fractions are separated from the non-condensable H2 rich gas, a valuable primary gas. The carbon containing catalyst from the treater is recycled to the regenerator/gasifier, and the catalyst after being regenerated (an exothermic reaction) is fed hot to the treater. Various fractions are removed from the fractionator as intermediates in the form of light napthas and light oils. The off-gas from the regenerator/gasifier is directed to a gas cleanup system to produce a valuable secondary gas. Both the primary gas and the secondary gas may be further utilized in the processing of the intermediates produced by the method, the primary gas being a source of H2 and the secondary gas being a source of thermal energy.
摘要:
An advanced method and facility for growing abundant crops for food together with a sustainable growth of biomass for energy within a farm setting measuring (by way of example) 600 acres and yielding some 180 bushels of corn per acre, amounting to a total farm yield of 108,000 bushels. By increasing the yield of 180 to 270 bushels per acre with drainage, irrigation, and a pond that accepts water in wet weather and dispenses water for irrigation in dry weather, and supplementing with fertilizer, the 108,000 bushels can be produced with only 400 acres, this freeing 200 acres for growing biomass to be harvested and delivered to a centralized processor (preferably in pellet form) and efficiently converts the biomass into a biofuel rich in H2 for transportation such as gasoline and a low-Btu biofuel to generate biopower while co-producing fertilizer to enhance growth of both crops and biomass.

摘要:
This invention relates to open-pit mining wherein crushed bitumen is fed into an enclosed pyrolyzer and heated under pressure in a reduced atmosphere where the cracking of asphalt results in a tar-free bitumen in the form of volatile matter containing a hydrogen rich, non-condensable syngas with vaporized light liquids and incandescent char. The syngas and vaporized light liquids are desulfurized and upgraded in a first hot gas cleanup, while part of the hot char is gasified with air into a fuel gas and into oil-free, tar-free, dry, solid tailings; the other part used as fuel for heating the pyrolyzer. The fuel gas passes through a second hot gas cleanup, producing clean, desulfurized lean gas ideal to generate clean, efficient electric power. Emitted CO2 is collected and converted to slow-release fertilizer. The tailings (clean sand and clay) reclaim the mine, while fertilizer enriched soil, topping the tailings, accelerates forest growth.
摘要:
An advanced method for processing a solid feedstock such as coal and a liquid feedstock such as bitumen wherein gases produced from such fossil fuel feedstocks are divided in a way as to polygenerate various by-products which includes the conversion of a waste gas (flue gas) containing nitrogen (N2) and carbon dioxide (CO2) generated from the combustion of said gases to produce an intermediate made of carbon (C) and nitrogen (N2) in the form of cyanogen which in turn is converted to a fertilizer such as oxamide. This approach obviates the necessity of CO2 capture and storage in a geologic formation. Besides the making of a fertilizer from a waste gas containing N2 and CO2, the other by-products can be power in the form of electricity and/or steam from a lean gas and liquid transportation fuel like methanol/gasoline, or chemicals from a hydrogen rich gas. The method is applicable to utility as well as to industry. This approach provides a comprehensive solution with respect to the use of energy from fossil fuels in an efficient and environmentally acceptable manner.
