A method for producing an ashless coal includes an extraction step, a separation step and an ashless coal acquirement step. In the extraction step, a slurry obtained by mixing a coal with a solvent is heated and thereby a solvent-soluble component of the coal is extracted. In the separation step, the slurry is separated into a solution of the solvent-soluble component of the coal and a solid content-concentrated liquid. In the ashless coal acquirement step, an ashless coal is obtained by evaporating and separating the solvent from the solution. The solvent is a mixture of a dissolution medium and a coal extraction accelerator added thereto. The solvent contains a bicyclic aromatic compound that is liquid at ordinary temperature. The coal extraction accelerator containing no nitrogen has two benzene rings and has at least one cyclic structure having no double bond.

Materials such as biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) and hydrocarbon-containing materials are processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, or oil sands, oil shale, tar sands, bitumen, and coal to produce altered materials such as fuels (e.g., ethanol and/or butanol). The processing includes exposing the materials to an ion beam.

A manufacturing method for a carbon heat source comprises: a step A1 of forming a first groove in a state where the plurality of carbon members are aligned in one line; a step A2 of changing, subsequent to the step A1 being performed, an orientation of the plurality of carbon members so that the first groove formed in the plurality of carbon members crosses relative to the first predetermined direction in a state where the plurality of carbon members are aligned in one line; and a step A3 of forming, subsequent to the step A2 being performed, a second groove in a state where the plurality of carbon members are aligned in one line.

A premium “fuel-grade” petroleum coke is produced by modifying petroleum coking technology. Coking process parameters are controlled to consistently produce petroleum coke within a predetermined range for volatile combustible material (VCM) content. The invention includes a process of producing a coke fuel, the method comprising steps: (a) obtaining a coke precursor material derived from crude oil and having a volatile organic component; and (b) subjecting the coke precursor material to a thermal cracking process for sufficient time and at sufficient temperature and under sufficient pressure so as to produce a coke product having volatile combustible materials (VCMs) present in an amount in the range of from about 13% to about 50% by weight. Most preferably, the volatile combustible materials in the coke product typically may be in the range of from about 15% to about 30% by weight. The present invention also provides methods for (1) altering the coke crystalline structure, (2) improving the quality of the coke VCM, and (3) reducing the concentration of coke contaminants. Fuels made from the inventive coke product and methods of producing energy through the combustion of such fuels are also included. Finally, novel environmental control techniques are developed to take optimal advantage of the unique characteristics of this upgraded petroleum coke.

Provided is an ash-free coal production method without the need to once re-liquefy and form an ash-free coal. The ash-free coal production method includes an extraction step of mixing coal with a solvent to prepare a slurry and heating the slurry to extract a solvent-soluble coal component; a separation step of separating a solution containing the solvent-soluble coal component from the slurry obtained from the extraction step; an ash-free coal obtaining step of evaporatively separating the solvent from the solution separated in the separation step to obtain an ash-free coal. The ash-free coal obtaining step in the production method is performed so that the solvent is evaporatively separated from the solution to give a liquid ash-free coal, and the liquid ash-free coal is brought into contact with a solidifier (e.g., water) to solidify into a predetermined shape.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, to produce ethanol and/or butanol, e.g., by fermentation. Hydrocarbon-containing materials are also used as feedstocks.

The invention provides a processing method for upgrading an organic phase substance by removing heavy element species from the organic phase substance originating from a resource substance in mild environmental conditions, and further provides a method for collecting removed heavy element species and a method for collecting other substances.The invention is constituted of a method for processing an organic phase substance, including: allowing an organic phase substance to coexist with a water phase, wherein the organic phase substance contains at least organic components originating from one or more selected from crude oil, bitumen, tar, residual fuel oil, petroleum residue, oil sands, tar-sand, asphaltene, fossil strata, cokes, oil-shale and coal, and contacting resultant of the above coexistence with halogen-containing chemical or chemicals, thereby extracting or depositing the heavy element species from the organic phase substance into the water phase; a plant for the method; and substances collected by the method.
摘要:
Measurements are taken of moisture, BTU/lb (British Thermal Units per pound), ash, forms of sulfur, volatile material, grindability, and absorption properties of any of a wide variety of mine-run solid fuels. Using that information, a dry electromagnetic process technology has been developed that can be controlled and monitored to selectively alter and enhance metallurgical solid fuel properties. Specific changes include altering the mechanical structure and chemical composition of solid fuels such as coal, coal coke or petroleum coke, increasing the BTU/lb to optimum levels, decreasing all forms of sulfur, and decreasing ash, while maintaining the BTU/lb of the fuels. A new family of solid fuel designer coals not found in nature can be produced via these methods and apparatus.

The invention provides low-cost, non-thermal methods to transform and beneficiate bulk materials, including low rank coals such as peat, lignite, brown coal, subbituminous coal, other carbonaceous solids or derived feedstock. High pressure compaction and comminution processes are linked to transform the solid materials by eliminating interstitial, capillary, pores, or other voids that are present in the materials and that may contain liquid, air or gases that are detrimental to the quality and performance of the bulk materials, thereby beneficiating the bulk products to provide premium feedstock for industrial or commercial uses, such as electric power generation, gasification, liquefaction, and carbon activation. The handling characteristics, dust mitigation aspects and combustion emissions of the products may also be improved.
