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. Furthermore, the portion of the components which boil easier, short-chained hydrocarbons, are significantly increased in the produced liquid product.
