摘要:
The invention relates to an apparatus for producing a pyrolysis product, the apparatus comprising a pyrolysis reactor for forming pyrolysis product fractions from raw material by fast pyrolysis, a condensing device for condensing gaseous pyrolysis product fractions to mainly liquid pyrolysis product fractions, a combustion boiler arranged in conjunction with the pyrolysis reactor for forming energy fractions, and feeding devices for feeding raw materials to the pyrolysis reactor and the combustion boiler. According to the invention, the apparatus comprises a separating device arranged substantially in conjunction with the pyrolysis reactor for separating other fractions from the gaseous pyrolysis product fractions after the pyrolysis and means for conducting other fractions than the gaseous pyrolysis product fractions from the separator to the combustion boiler.

The invention relates to a method for producing combustible gas from solid feed materials containing carbon, comprising the following steps: introducing the feed materials into at least one entrained-flow degasification reactor and at least partially degassing the feed materials, a reaction gas and a solid remainder, in particular conversion coke, thus being produced; removing the solid remainders; introducing at least a partial amount of the remainders into a coal gasification reactor and gasifying the solid remainders, a reaction gas and ash or slag being produced; introducing the reaction gases from the coal gasification reactor into the at least one entrained-flow degasification reactor for the final degassing of the feed materials; introducing at least part of the reaction gases from the at least one entrained-flow degasification reactor into a reforming reactor; and cracking the tar fraction of the reaction gas in the reforming reactor in order to obtain a combustible gas.
摘要:
A process for obtaining petrochemical products from a carbonaceous feedstock is provided. The carbonaceous feedstock may be coal, coke, lignite, biomass, bitumen and the like. The carbonaceous feedstock is pulverized and fed to a pyrolysis reactor where the feedstock is pyrolyzed at 700-1000° C. at a pressure of 2-25 bar for 2-10 seconds, wherein the feedstock is entrained in hot syngas during the pyrolysis process.

The present invention relates to a process and a plant for producing char and fuel gas. In a fluidized bed reactor (1) carbonaceous material like coal is degasified with oxygen containing gasses in the presence of steam. More than 60 % of the fixed carbon in the carbonaceous material is recovered in the produced char.
