| Number | Title | Issue Date |
| 7255743 | Method of making synthetic gems comprising elements recovered from remains of a species of the kingdom animalia This invention is a method of making a synthetic gem comprising elements recovered from remains of a species of the Kingdom Animalia, comprising the steps of collecting substantially pure carbon from the remains and creating gems from the carbon using crystal growth... | 08/14/2007 |
| 5859120 | Carbon black and processes for manufacturing Carbon blacks containing silicon and a process for manufacturing them. The carbon blacks containing silicon are suitable as reinforcing carbon blacks for rubber mixtures and give the latter viscoelastic properties such as reduced rolling resistance in tir... | 01/12/1999 |
| 5817287 | Carbon black refractory system A refractory system for a reactor for producing carbon black. The system comprises a plurality of refractory bricks having an elongate axis arranged to provide at least one path through which a gas can flow. The path extends substantially perpendicular to... | 10/06/1998 |
| 5505929 | Method for manufacturing high purity graphite material and manufacturing apparatus for use thereof A method for manufacturing a high purity graphite material comprises a baking process of a carbon material, a graphitizing process of the material and a highly purifying process of the material in sequential order, the highly purifying process of the mate... | 04/09/1996 |
| 5427762 | Process for the conversion of carbonaceous feedstocks to particulate carbon and methanol A process for the production of a pollutant-free particulate carbon (i.e., a substantially ash-, sulfur- and nitrogen-free carbon) from carbonaceous feedstocks. The basic process involves de-oxygenating one of the gas streams formed in a cyclic hydropyrol... | 06/27/1995 |
| 4978649 | Porous carbonaceous material The present invention relates to physical chemistry. The material is made as a three-dimensional matrix with a pore volume of from 0.2 to 1.7 cm3 /g. The matrix is formed by bent layers of carbon of 100-10,000 Å thickness and 100-10000 Å radius of... | 12/18/1990 |
| 4762528 | Fluid fuel from coal and method of making same Coal is gasified to produce carbon monoxide which is converted to carbon by a reverse Boudouard reaction The carbon dioxide is recycled and reacted with coal to create more carbon monoxide by the Boudouard reaction The resulting carbon is recovered and mixed w... | 08/09/1988 |
| 4372937 | Waste heat recovery Combustion products containing particulate solids such as carbon black are quenched by indirect heat exchange and the build up of solids deposits on the heat exchange surfaces is minimized or deposits on the heat exchange surfaces are removed by providing... | 02/08/1983 |
| 4263268 | Preparation of porous carbon Porous carbon, suitable for instance for chromatography and as a catalyst support is formed by depositing carbon into the pores of a porous inorganic template such as silica gel, porous glass or a porous oxide, e.g. alumina, and thereafter removing the te... | 04/21/1981 |
| 4112060 | Method for the production of carbon black from liquid or gaseous hydrocarbons The hydrocarbon material to be decomposed and the combustion-supporting gas, such as air, are conditioned before admission to the reaction chamber to provide formation of carbon black under conditions highly controllable as to output product properties, p... | 09/05/1978 |
