  • Patent number: 4652430
    Abstract: An apparatus for the multi-stage refining of organic bulk materials according to the fluidized bed principle comprising a plurality of horizontally aligned cells (23) including an upper drying chamber (1), a middle degasification chamber (2) and a lower refining chamber (3) separated from each other by an individual gas permeable floor (19) or a gas impermeable floor (20). Adjacent cells are connected to each other by common discharge/charge chutes having vertical separation walls extending therein.

  • 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.

  • Patent number: 4533438
    Abstract: A two-step method and apparatus, according to the fluidized bed principle, for the production of coke, rich gas and pyrolysis tar, with the object of executing the method in a compact apparatus arrangement, with high energy efficiency and high throughput capacity.This is accomplished by a sequence in which the fine grains removed from the drying vapor mixture are removed from the actual pyrolysis process, and a hot gas, alien to the carbonization, is used as fluidization medium in the pyrolysis reactor, and with a hot gas-high performance separator being used for the dust separation from the pyrolysis gas, with the combustion exhaust gas produced in the combustion chamber being used for the indirect heating of the fluidization medium, for the pre-heating of the gas, which is alien to the carbonization, and for the direct heating in the dryer.
