Problems solved by technology

[0005] However, the prior art biogas systems have the disadvantage that especially lignocellulosic starting materials such as straw are not fermented at all or hardly or only at a very slow rate.
[0017] German patent DE 198 58 187 C2 describes a method and an apparatus for the reduction of the organic fraction of spoilable substances, in which a first anaerobic digestion stage is combined with thermal decomposition, followed by a

example 1

[0132] With the repowering of the existing plant, the final repository starts to have a high solids feedstock content, the fermentation residue is removed from the final repository (1) and directed to the separator (2), whereby e.g. 25% is separated oTS solid component (51), and 4% oTS fluid component (52), the liquid separated by this separator is temporarily stored in the fluid container (3) of the separator, and heated for anti-frost if necessary.

[0133] This solid component ( 51 ) is also temporarily stored and if necessary conveyed to the inlet side of the solid mixer ( 8 ) for mixing with the input material. The 4% oTS fluid composition (52) is drawn from the storage vessel (3) by a pressure-generating pump (31) and compressed at a supply pressure of up to 5 bar.

[0134] The low-viscosity and chemically basic separator fluid (53) circulates with a slight pressure drop through a heat exchanger (21), where its heat is absorbed by a heated counterflow (57), which is heat...

example 2

[0143] In continuous operation, the biomass production obtained by the system according to the invention is almost completely available and recoverable in the fermenter; whereby, over several months, in the final repository (1) the organic solids content (TS or o (=organic)TS) drops below 4%, at which point the separator (2) is no longer needed and the final repository liquid can be used directly as a liquid feedstock (52).

example 3

[0145] As the starting material, dry straw should mainly be used, for example, for the following reasons, because dry straw is a garbage waste generated under large-scale agricultural operations, and in this case, the straw must be chopped; the TS content of straw is about 85% The treatment must be mixed with a liquid such as a fermentation broth, however, this leads to an increasingly high mineral content, and water is then added to this feed preparation and mixed with it to keep the fermenter from the mineral in the final repository. The concentration of the substance will not be too high for a long time.

Abstract

The invention relates to a method and to a device for generating a biomass preparation (biomass composition), particularly preparation of fermentable biomass. Through combining biological, mechanical and/or microorganism activators for thermal activation, biomass reactants difficult to digest, especially lignin in biomass, can be digested and allowed to be fermented.

Description

[0001] Technical field: [0002] The present invention relates to a plant and method for biomass production (biomass combination), in particular to a fermentable biomass production, which is activated by a combination of biological, mechanical and / or microbial activators thermally, enabling it to Digest and make fermentable bioreactors that are difficult to digest, especially lignin in biomass. [0003] Background technique: [0004] Traditional biogas plants work with hydrolysis and methanation bacteria, which metabolize easily fermentable carbon compounds such as sugars into methane. Generally speaking, biogas is a gas mixture produced by anaerobic fermentation and decay of organic substrates. The main energy source of biogas is mainly methane (about 50-80% of the volume of the starting material), carbon dioxide (19-49% of the volume %) and water vapor (1-4% by volume). When combusted, it can be converted, for example, into energy, oxygen and carbon dioxide. [0005] Howev...
