Patent number: 8790420Abstract: The present invention provides a method for producing a high-quality reduced metal using an upgraded coal as a carbonaceous material to be incorporated. In the method, coal is first aged by heating in an organic solvent to produce upgraded coal for metallurgy having higher thermal plasticity than that of the coal. Then, a mixture of the upgraded coal for metallurgy and a metal oxide-containing raw material is agglomerated by an agglomerator, and the resultant agglomerates are reduced by heating in a furnace and then melted by further heating to produce a reduced melt. The reduced melt is cooled and solidified in the furnace to produce a reduced solid. The reduced solid is discharged to the outside of the furnace and slag is removed using a screen to recover a metal as a reduced metal.Type: GrantFiled: July 29, 2010Date of Patent: July 29, 2014Assignee: Kobe Steel, Ltd.Inventors: Takao Harada, Hidetoshi Tanaka, Isao Kobayashi, Noriyuki Okuyama, Takuo Shigehisa

Patent number: 8425633Abstract: Methods, process, apparatus, equipment, and systems are disclosed for converting biomass into bio-oil fractions for chemicals, materials, feedstocks and fuels using a low-cost, integrated fast pyrolysis system. The system improves upon prior art by creating stable, bio-oil fractions which have unique properties that make them individually superior to conventional bio-oil. The invention enables water and low-molecular weight compounds to be separated into a final value-added fraction suitable for upgrading or extracting into value-added chemicals, fuels and water. Initial bio-oil fractions from the process are chemically distinct, have low-water content and acidity which reduces processing costs normally associated with conventional bio-oil post-production upgrading since fewer separation steps, milder processing conditions and lower auxiliary inputs are required. Biochar is stabilized so that it can be handled safely.Type: GrantFiled: December 23, 2011Date of Patent: April 23, 2013Assignee: Avello Bioenergy, Inc.Inventors: Dennis Stephan Banasiak, Cody James Ellens, Anthony Joseph Sherwood Pollard, Jared Nathaniel Brown

Patent number: 8409303Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.Type: GrantFiled: February 11, 2011Date of Patent: April 2, 2013Assignee: SGC Advisors, LLCInventors: Norman L.

Patent number: 6833011Abstract: An ablation resistant, monolithic, activated, carbon foam produced by the activation of a coal-based carbon foam through the action of carbon dioxide, ozone or some similar oxidative agent that pits and/or partially oxidizes the carbon foam skeleton, thereby significantly increasing its overall surface area and concurrently increasing its filtering ability. Such activated carbon foams are suitable for application in virtually all areas where particulate or gel form activated carbon materials have been used. Such an activated carbon foam can be fabricated, i.e. sawed, machined and otherwise shaped to fit virtually any required filtering location by simple insertion and without the need for handling the “dirty” and friable particulate activated carbon foam materials of the prior art.Type: GrantFiled: October 12, 2001Date of Patent: December 21, 2004Assignee: Touchstone Research Laboratory, Ltd.Inventors: Darren Kenneth Rogers, Janusz Wladyslaw Plucinski

Patent number: 6833012Abstract: Petroleum or coal tar pitch-based cellular or porous products having a density of preferably between about 0.1 g/cm3 and about 0.8 g/cm3 are produced by the controlled heating of mesophase carbon materials derived from coal tar or petroleum pitch having a softening point in excess of about 300° C. and preferably between about 300 and about 400° C. in a “mold” and under a non-oxidizing atmosphere. The porous product thereby produced, preferably as a net shape or near net shape, can be machined, adhered and otherwise fabricated to produce a wide variety of low cost, low density products.Type: GrantFiled: October 12, 2001Date of Patent: December 21, 2004Assignee: Touchstone Research Laboratory, Ltd.Inventor: Darren Kenneth Rogers

Patent number: 6749652Abstract: According to the present invention there is provided a porous coal-based material having a density of between about 0.1 g/cm3 and about 0.6 g/cm3 that is produced by the controlled heating of small coal particulate in a “mold” and under a non-oxidizing atmosphere. The coal starting material preferably exhibits a free swell index of between about 3.5 and about 5.0 and most preferably between about 4.0 and about 4.5. The porous product thereby produced can be machined, adhered and otherwise fabricated to produce a wide variety of low cost, low density products, or used in its preformed shape as a filter, heat or electrical insulator etc. Such porous products, without further treatment exhibit compressive strengths of up to about 6000 psi. Further treatment by carbonization or graphitization yields products that can be used as electrical or heat conductors. Methods for the production of these coal-based cellular products are also described.Type: GrantFiled: July 10, 2001Date of Patent: June 15, 2004Assignee: Touchstone Research Laboratory, Ltd.Inventor: Darren Kenneth Rogers

Patent number: 6656239Abstract: According to the present invention, carbon foams are produced largely in accordance with the methods described in U.S. patent application Ser. No. 09/902,828, but with starting materials that comprise from about 10 to about 90% by weight of ground petroleum pitch and from about 90 to about 10% by weight of bituminous coal particulate exhibiting a free swell index of from about 3.5 to about 5.0.Type: GrantFiled: February 5, 2002Date of Patent: December 2, 2003Assignee: Touchstone Research Lab.Inventors: Darren Kenneth Rogers, Janusz Wladyslaw Plucinski

Patent number: 6656238Abstract: A method for the manufacture of coal-based carbon foams from a coal particulate starting material that comprises blending from 1 to about 10% by weight of pitch with the coal particulate before foaming. Blends of coal-based particulate with 1 to about 10% by weight of pitch as well as coal-based carbon foams manufactured from such blends are also described.Type: GrantFiled: September 17, 2001Date of Patent: December 2, 2003Assignee: Touchstone Research Lab.Inventors: Darren Kenneth Rogers, Janusz Wladyslaw Plucinski
