| A binder for making metallurgical coke and a process for making the binder. The binder is thermally hydrocracked pitch which has been de-ashed. The binder may be mixed with low rank bituminous coal, heated to make coke which is acceptable as a metallurgical coke. The thermally hydrocracked pitch may be de-ashed by mixing with a solvent, and separating the insoluble portions from the soluble portions using a centrifuge. The soluble portions may be separated from the solvent, for example, in a fractionating section, and used as the binder with poor coking coal to make metallurgical coke. | ||||||

| The present invention relates to a process for the recovery of hydrocarbon oils from other heavier oils such as vacuum residua and, more particularly, to an improved process for deasphalting petroleum oils containing those asphalts. In one aspect of the invention, the process treats a solvent which has contacted the heavy oil with a gaseous antisolvent to separate effectively and usually without distillation, the solvent from the extracted oil.

| 197 | Supercritical selective extraction of hydrocarbons from asphaltic petroleum oils | US157728 | 1980-06-09 | US4354928A | 1982-10-19 | Costandi A. Audeh; Tsoung Y. Yan |
| An asphalt containing petroleum oil is deasphalted and extracted by contacting the oil with a solvent maintained at its critical temperature and pressure. With the solvent at its critical temperature and pressure, extraction of the valuable hydrocarbon oils present in the asphaltic feedstock is effected by way of vapor-liquid phase separation which serves to decompose the metal complexes present in the feedstock, thus reducing the metal content of the extracted hydrocarbon oil. Examples of solvents employed in the process of the invention include C.sub.4 -C.sub.10 cuts of typical refinery streams, benzene, toluene, ethylene glycols and the like. In one process embodiment, promoters or catalyst are employed to further reduce the metal content of the extracted hydrocarbon oil. | ||||||
| 198 | Process for separating bituminous materials and recovering solvent | US237376 | 1981-02-23 | US4315815A | 1982-02-16 | Junior A. Gearhart |
| A process and apparatus for separating a solvent from a bituminous material by pressure reduction and steam stripping without carry-over of entrained bituminous material. A fluid-like phase comprising bituminous material and solvent is reduced in pressure by passage through a pressure reduction valve to vaporize a portion of the solvent. The reduction in pressure also results in dispersing a mist of fine particle size bituminous material in the vaporized solvent. The stream of vaporized solvent, fine particle size bituminous material and fluid-like bituminous material then is introduced into a steam stripper through an inlet horn that imparts a centrifugal motion to the stream. The inlet horn contains a plurality of corrugated vanes which utilize the centrifugal motion to create turbulence in the stream within the inlet horn. The turbulence causes at least a portion of the fine particle size bituminous material to impinge on the surfaces of the inlet horn and recombine with the fluid-like material from which it was formed. The vaporized solvent and steam are withdrawn from the stripper substantially free of entrained bituminous material. | ||||||

| 200 | Process for separating bituminous materials | US164606 | 1980-06-30 | US4279739A | 1981-07-21 | Jack W. Roach |
| A process for separating a solvent from a bituminous material by pressure reduction and steam stripping without carry-over of entrained bituminous material. The fluid-like phase of bituminous material and solvent is reduced in pressure and introduced into a steam stripper. The solvent vaporizes upon pressure reduction and a mist of fine bituminous material particles forms and becomes dispersed in the vaporized solvent. The vaporized solvent and associated mist is separated from the bituminous material in the stripper and is withdrawn from the steam stripper and introduced into a condenser. The solvent and steam from the stripper condense, a substantial portion of the mist of entrained particles solidifies and an emulsion of water and fluid-like bituminous material from the mist forms. The liquid stream is withdrawn from the condenser and introduced into a separator. The liquid stream separates in the separator into an upper fraction comprising solvent, a middle fraction comprising emulsion and a lower fraction comprising water and the solidified particles of bituminous material. The liquid solvent is removed by passage over a weir in the separator and recovered. The emulsion, water and solids can be removed from the base of the separator for disposal. | ||||||
