  • Patent number: 9937476
    Abstract: A method of operating a slurry phase apparatus includes feeding one or more gaseous reactants into a slurry body of solid particulate material suspended in a suspension liquid contained inside a vessel. The one or more gaseous reactants are fed into the slurry body through a gas distributor having downward facing gas outlets and are fed towards a fluid impermeable partition spanning across the vessel below the gas distributor. The partition divides the vessel into a slurry volume above the partition and a bottom volume below the partition. A differential pressure is maintained over the partition between predefined limits by manipulating or allowing changes in the pressure in the bottom volume by employing a pressure transfer passage establishing flow or pressure communication between the bottom volume and a head space above the slurry body.

  • Patent number: 4735706
    Abstract: In a coal liquefaction process an aqueous slurry of coal is prepared containing a dissolved liquefaction catalyst. A small quantity of oil is added to the slurry and then coal-oil agglomerates are prepared by agitation of the slurry at atmospheric pressure. The resulting mixture of agglomerates, excess water, dissolved catalyst, and unagglomerated solids is pumped to reaction pressure and then passed through a drainage device where all but a small amount of surface water is removed from the agglomerates. Sufficient catalyst for the reaction is contained in surface water remaining on the agglomerates. The agglomerates fall into the liquefaction reactor countercurrently to a stream of hot gas which is utilized to dry and preheat the agglomerates as well as deposit catalyst on the agglomerates before they enter the reactor where they are converted to primarily liquid products under hydrogen pressure.

  • Patent number: 4725350
    Abstract: Process and apparatus for extraction of oil and hydrocarbons from crushed hydrocarbonaceous solids, such as tar sands, involving the pyrolyzing of the said solids with syn gas rich in hydrogen, and preferably syn gas obtained from the gasification of coal. Crushed hydrocarbonaceous solids are treated with hot syn gas containing hydrogen at an elevated temperature in a rotary kiln where the crushed solids are cascaded into the hot syn gas containing hydrogen for sufficient time to strip the volatile liquids and gases found in the said solids, removing the vaporized liquids, enriched syn gas and spent crushed solids from the kiln, fractionating the vaporized liquids and enriched syn gas into desired fractions, and utilizing the enriched syn gas in the preparation of desired by-products. The apparatus includes an improved rotary kiln which speeds the pyrolysis of the crushed solids.

  • Patent number: 4708788
    Abstract: A liquefaction process for coal lignite or heavy oil is disclosed utilizing a hydrogen-donor solvent. The preferred hydrogen-donor solvent is recovered as a vapor from the liquefaction mixture. The preferred method for converting the vapor into active hydrogen-donor solvent form involves passage of the vapor over a catalyst bed positioned in the vapor space of the catalyst vessel. Novel apparatus for so positioning the catalyst bed is also disclosed.

  • Patent number: 4696735
    Abstract: A practically isothermal temperature distribution of the reactor contents is obtained, especially for high temperature and pressurized hydrogenation reactors operating in the sump-phase by a hydrogenation gas passing over the outer region of the reaction chamber, so that the hydrogenation gas cools the reaction in the chamber. Additionally, the reaction heat which is extracted by the hydrogenation gas is used to heat the reaction components at a stage in the hydrogenation process. The major portion of the reaction heat is used to heat charges, preferably for the reactors, which charges contain no appreciable amounts of solid material. These charges, preferably comprising hydrogenation gas, preferably pass through a jacket space between the reaction chambers and the external portion of the reactors, which external portions preferably make contact with the atmosphere.

  • Patent number: 4605487
    Abstract: Method for the production of liquid products, particularly, tar, from organic bulk materials.The invention relates to a method, whereby in an apparatus in one or a multiple of refining stages, organic bulk goods are refined to economically significant base materials, so that they are suitable, either directly or indirectly, for the production of gasifier or diesel fuel.The technical object is to utilize a fluidizing medium, with the help of which it is possible to produce, in a reaction chamber, an increased yield of liquid products, especially tar.According to the invention, the problem is solved by supplying a hydrocarbonaceous gas, especially a gas containing methane and hydrogen, as a fluidizing medium in the individual refining stages, whereby, under the particular refining conditions, there results a decrease of the portion of methane and hydrogen, and a comparative increase of the portion of the liquid product, especially of the portion of tar.
