| Number | Title | Issue Date |
| 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 |
| 4873214 | Carbonaceous material for production of hydrogen from low heating value fuel gases A process for the catalytic production of hydrogen, from a wide variety of low heating value fuel gases containing carbon monoxide, comprises circulating a carbonaceous material between two reactors--a carbon deposition reactor and a steaming reactor. In ... | 10/10/1989 |
| 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 |
| 4519894 | Treatment of carbonaceous shales or sands to recover oil and pure carbon as products A carbon-containing solid (such as oil shale or tar sand) is treated with air in a six-stage vertical shaft to make producer gas, oil and a pure carbon as products. The top and bottom stages of the vertical shaft are fed to pre-heat incoming solid and to ... | 05/28/1985 |
| 4391793 | Plant for thermochemical water dissociation by solar energy Plant for thermochemically dissociating water by solar energy, the improvement therein including at least one substance enclosed in electromagnetic fields and heatable by solar energy absorption to a temperature above 1.100° C., and method of operation o... | 07/05/1983 |
| 4216194 | Method of producing methane and carbon Methane and/or carbon are produced when carbon monoxide and hydrogen are passed through a molten salt bath containing suspended therein a finely divided material capable of catalyzing the conversion of carbon monoxide and hydrogen to carbon and/or methane... | 08/05/1980 |
| 4185083 | Manufacture of finely divided carbon Finely divided carbon is manufactured by a process including producing a gaseous stream containing carbon monoxide by reacting coal and air in a slagging ash gasifier, separating carbon monoxide from the gaseous mixture, and disproportionating the carbon ... | 01/22/1980 |
| 4128624 | Method for introducing carbon into evacuated or pressurized reaction vessels and reaction products therefrom A method for introducing ash-free solid carbon into a reaction vessel while under pressure or vacuum conditions and the conversion of said carbon to a metal carbide for the production of acetylene for use as such and as a precursor in the preparation of o... | 12/05/1978 |
| 4116680 | Coproduction of iron and carbon black A process wherein a blast furnace is operated with oxygen instead of air to provide hot metal and a top gas of essentially carbon monoxide which is disproportionated, or decomposed, to carbon black.... | 09/26/1978 |
