    摘要： A process for the gasification of carbonaceous agglomerates in a reactor at a pressure of the range of 5 to 150 bar. The agglomerates are fed into said reactor from a storage zone located above the reactor and form a fixed bed in the reactor, in which they slowly descend when gasified. At least two gasification agents selected from the group consisting of oxygen, air, steam and carbon dioxide are introduced into said reactor through the bottom and rise through said fixed bed. Solid ash or liquid slag is discharged below said fixed bed and a steam-containing product gas is tapped from the reactor above said fixed bed. In order to minimize or prevent the condensation of steam on the agglomerates in the storage zone, the invention provides for a controlled atmosphere almost entirely free of oxygen and steam which is introduced into the storage zone at a pressure approximately equal to the pressure of the product gas.

    摘要： The container communicates through an outlet, which is adapted to be closed with a lock chamber, which is adapted to be emptied and is provided with a pressure-relief valve. When it is desired to empty the lock chamber the volume which is available in the lock chamber for the gas is initially increased so that the pressure in the lock chamber is reduced. Thereafter the lock chamber is opened.

    摘要： In a reactor, granular feedstock having particle sizes in the range from about 0.5 to 15 mm is subjected in a moving bed to a countercurrent extraction at a temperature in the range from 20.degree. to 150.degree. C. and under a pressure in the range from 50 to 400 bars by a continuously supplied solvent which is in a liquid or supercritical state. A mixture of valuable substances and solvent is withdrawn from the upper portion of the reactor. The solvent is separated from the valuable substances by a pressure relief and/or temperature rise and is recycled to the reactor. The extraction residue is withdrawn from the lower end of the reactor. Respective locks are used to charge the feedstock into the reactor and to discharge the extraction residue from the reactor. Solvent and an entrainer are supplied to the reactor at different locations. Outlet ducts having a length of 0.1 to 1 m are preferably used to deliver the feedstock onto a moving bed in the reactor so that a free space is provided over the bed.

    摘要： Coarse-grained solid fuels in particle sizes of at least 2 mm are gasified under a pressure of 5 to 150 bars in a fixed bed which is slowly descending and into which the gasifying agents are introduced from below whereas the incombustible mineral constituents are withdrawn as solid ash or liquid slag from the lower end of the bed. Fine-grained solid fuels are gasified in a fluidized bed under a pressure of 1 to 100 bars. Oxygen, steam and/or carbon dioxide are used as gasifying agents for the gasification in the fixed bed and in the fluidized bed. The product gas from the fluidized-bed gasifier has a temperature of 700.degree. to 1200.degree. C. and is indirectly cooled with water. The resulting steam is fed as gasifying agent to the fixed-bed gasifier. The product gas from the fixed-bed gasifier can be indirectly cooled to produce steam and at least part of said steam is fed as gasifying agent to the fluidized-bed gasifier. The steam fed as gasifying agent to the fixed-bed gasifier has a temperature of about 300.degree. to 600.degree. C., preferably of about 400.degree. to 500.degree. C.The steam produced by an indirect heat exchange with the product gas from the fixed-bed gasifier can be superheated by an indirect heat exchange with the product gas from the fluidized-bed gasifier before said steam is fed as gasifying agent to the fluidized-bed gasifier.

    摘要： Particulate solids are fed into a pressure reactor operated under a pressure of 5-150 bars by means of a guide cylinder which is secured to the reactor and surrounds the reactor inlet. The guide cylinder is adapted to be closed and a stationary feed conduit is directed towards the guide cylinder. A cylinder container, which is gastightly guided in the guide cylinder and has a bottom which is adapted to be closed, is moved up and down in the guide cylinder and when the bottom of the cylinder is open and the reactor inlet is closed the material flows out of the container into the guide cylinder whereas the bottom of the container is closed and the same is moved toward the open reactor inlet to displace gases into the reactor. The device for carrying out the process includes a guide cylinder secured to the reactor and surrounding the reactor inlet. The guide cylinder is adapted to be closed. A stationary feed conduit is directed towards the guide cylinder and a container is gastightly guided in the guide cylinder and is movable up and down therein and has a bottom that is adapted to be closed.

    摘要： In addition to ash and coke, the gasification residue contains alkaline earth metal sulfide and alkaline earth metal oxide because desulfuring agents have been supplied to the gasifier. At temperatures from 5.degree. to 80.degree. C. the gasification residue is mixed with an acid-containing aqueous solution so that a gas which is rich in H.sub.2 S is produced. Ash, coke, and alkaline earth metal salt are supplied to a flotation zone, in which coke is separated. A solid residue which contains ash and alkaline earth metal salt is withdrawn from the flotation zone. Carbonic acid or dilute sulfuric acid is preferably used as an acid.
