| Number | Title | Issue Date |
| 4098649 | Conversion of organic waste material Apparatus and the method of converting organic material such as that separated from municipal and industrial waste into useful products by using a form of an extruder in a continuous destructive distillation process and in which the material being process... | 07/04/1978 |
| 4083751 | Continuous feed pyrolysis chamber for decomposing solid waste A pyrolysis reactor decomposes solid organic waste materials by heating the materials with a fast fluidized particulate source of heat which are admitted to one end of a chamber through first and second inlet pipes. The products of decomposition together ... | 04/11/1978 |
| 4078973 | Loop pyrolysis process for organic solid wastes Particulate organic solid waste is pyrolyzed in the presence of an inert particulate source of heat and a carrier gas in a pyrolysis reactor to form a carbon containing solid residue of pyrolysis, pyrolytic oils and gases. The particulate source of heat a... | 03/14/1978 |
| 4077847 | Solid waste disposal system There is provided a system for segregating through comminution and classification solid waste into ferrous metal, inorganic, and organic fractions. The inorganic fraction is further classified into aluminum and glass fractions. The organic fraction is fur... | 03/07/1978 |
| 4064018 | Internally circulating fast fluidized bed flash pyrolysis reactor Solid carbonaceous materials are pyrolyzed by feeding the carbonaceous material along with a particulate source of heat to a fast fluidized bed contained within a vertically disposed duct. An internally circulating stream of spent particulate source of he... | 12/20/1977 |
| 4056443 | Coke production Coke is produced with high yield and low sulfur by heating and drying ground coking coal at 200° to 300° C. for 15 to 120 minutes in air, and then heating in three semicoking stages in fluidized bed reactors. The first semicoking stage is 300° to 470°... | 11/01/1977 |
| 4055471 | Method of restricting the formation of dust when feeding coal into coke ovens A method for inhibiting dust formation while feeding coal into a coking chamber, comprising preheating coal and subsequently contacting the coal with an aqueous solution of 30-70% by weight of waste sulfite liquor in amounts of about 0.5 to 1.0 parts by w... | 10/25/1977 |
| 4053569 | Upgrading coal for coking purposes The invention relates to the upgrading of coal for coking purposes and improved cokes resulting from such upgrading. Pitch obtained as a by-product of pressure-gasification (Lurgi-process) is used as an additive either alone or blended with SRC. The addit... | 10/11/1977 |
| 4050990 | Method and apparatus for producing form coke A method of producing form coke that is coke having pieces of substantially identical form using a heated shaft furnace comprises mixing fine coke with a caking coal and pressing the mixture at temperatures at which the mixture is plastic in order to form... | 09/27/1977 |
| 4045187 | Carbonaceous material A novel carbonaceous material derived from solid carbonaceous fossil fuel, in particular low rank coal, such as brown coal, having a low ash and sulphur content, is prepared by deoxygenation and dewatering in the presence of hydrogen and a solvent having ... | 08/30/1977 |
| 4024022 | Method of inhibiting dust formation when feeding coal into coking chambers One of the problems encountered when feeding dry or preheated coal into coking chambers resides in that dust is generated. This dust is indesirable since it can form deposits which are difficult to remove. A method of inhibiting the dust formation when co... | 05/17/1977 |
| 4001105 | Hydrocracking process for the production of synthetic fuels This invention is a process for the continuous and simultaneous retorting and hydrocracking of the carbonaceous materials found in such carbon containing solids as oil shale, coal, tar sands, lignite, and/or other carbon containing solids, and/or heavy li... | 01/04/1977 |
| 3962043 | Process for producing fine-grained coke by degasification of coal Fine-grained coke is produced by the degasification of fine-grained coal by a process which includes the following steps: A. mixing the coal to be degasified with recirculated, heated, fine-grained coke in a mixing zone; B. withdrawing gases and vapors produce... | 06/08/1976 |
| 3939057 | Process for treating oil shale A process and apparatus for decomposing kerogen and recovering oil, high BTU gas and energy for the process wherein a crushed oil shale is fed to a rotary preheater (300° to 350° F.) hence into a rotary retort (850°-1050° F.) where the kerogen is deco... | 02/17/1976 |
| 3933443 | Coking component A coking component consisting essentially of a mixture of 10 to 60 percent of finely ground coke and at least one carbon-containing substance selected from coking coal, non-coking coal, petroleum coke, semi-coke or lignite. The carbon-containing substance... | 01/20/1976 |
