Definitions
- the object is achieved by a method according to the main claim and a device according to the independent claim.
- a method for the production of hydrocarbons wherein a carried out in a first reaction unit generating carbon monoxide and carbon dioxide with the addition of oxygen;
- Hydrogen as starting materials for the first reaction unit and Ver ⁇ use provided by means of the electrolyzer Hydrogen ⁇ as an educt for the second reaction unit.
- hydrocarbon is to be understood here in a broad sense. That is the target molecule containing carbon and hydrogen, but may contain other elements such as oxygen and nitrogen ⁇ material. Thus beispiels- this term as Also to understand alcohols, ethers or amino acids.
- a high-energy reactant is also needed to convert CO2.
- the necessary energy as in chemical synthesis, can also supply H2. This can be regeneratively produced by excess current or excess electrical power by means of electrolysis. Alternatively, the bacteria can also use CO for energy.
- a peculiarity of the gas fermentation of CO2 and H2 is that the presence of CO has a positive influence on the selectivity and the yield of some target products such as ethanol or butanol and in many cases makes the synthesis of the target products possible in the first place.
- Al ⁇ lerdings is currently produced mainly from fossil CO Energy ⁇ carriers such as coal, natural gas or oil industri ⁇ ell on a large scale. This invention report is therefore concerned with the goal of decarbonising CO from regenerative biogas.
- a Gasfermentationsstrom can be operated with a gas mixture of H2, CO and CO2, wherein the CO content by a
- Reforming biogas can be obtained.
- the reforming can be autothermal, that is without heating and without active cooling.
- the temperature required for reforming can be achieved by a partial oxidation, which can be initiated by the addition of pure oxygen (O 2 content> 90%).
- the reforming reactor can be operated so that its outlet temperature is in the range of 550 ° C to 1000 ° C, in particular in the range of 580 ° C to 850 ° C.
- Part of the hydrogen for gas fermentation can come from an electrolyzer in which water is electrochemically decomposed.
- the resulting oxygen can be passed into the reforming reactor. According to the invention, at least 60% of the oxygen produced in the electrolysis can be used, at least 80% being particularly advantageous.
- water can be converted in the reforming reactor.
- the molar ratio of water to oxygen can advantageously in the range 1.8 to 3.8 lie ⁇ gen. This ratio has a direct impact on the molar ratio of CO2 / CO for from the reforming reactor gas emerging. The latter ratio is then in the range of 2 to 5.
- the reforming reactor may contain a catalyst containing Ni, Co, Zn, Cu and / or Mg, Ti, Pt and / or a side earth element such as cerium, yttrium or lanthanum.
- the hydrogen produced in the electrolysis can be passed together with the gas mixture produced during the reforming in a gas fermentation.
- This gas mixture may also contain hydrogen, its proportion may be in the entire introduced into the second reaction unit hydrogen Zvi ⁇ rule about 20% and about 80%.
- the gas fermentation carried out is advantageously anaerobic.
- the following microorganisms of the Clostridium (C) type such as, for example, C. ljungdahlii, C. autoethanogenum, C. ragsdalei, C. carboxidivorans, C. coskatti or the type
- thermoautotrophica or Acetobacterium woodii or a co-culture of one or more microorganisms Particularly advantageous products of the gas fermentation are special into ⁇ ethanol, methanol, butyrate, formic Bezie ⁇ hung, a formate, a complex of acetyl and coenzyme A "activated acetate", acetone, butanol, hexanol, propanol, 2, 3-butanodiol, or 1 , 3-propanodiol.
- the reacted in the reforming reactor gas can be preheated with hot product gas from the reforming reactor through a heat exchanger.
- the gas that is fed into the gas fermentation can Weni ⁇ ger than 1000 ppmv containing O2 and less than 1% CH4.
- Reactor type may be an adiabatic fixed bed reactor, honeycomb reactor, fluidized bed reactor or a tube bundle reactor.
- a gas storage for oxygen and hydrogen may optionally be provided. This is not shown in the figures. To the temporal operation of biogas plant and electrolysis can decouple this memory for oxygen and hydrogen optionally.

- the biogas 12 contains methane and also a large proportion of CO2 ⁇
- the methane is almost completely converted in a reforming reactor Cl, for which purpose pure oxygen 5, namely for a partial oxidation, and water 2, namely for steam reforming, are used.
- the oxygen comes from a water electrolyzer 3, which in this case also formed hydrogen 4 is mixed with the in reforming ent ⁇ battingen gas and a gas operated anaerobic fermentation plant C2 supplied.
- Particularly advantageous is the use of pure oxygen 5, in particular instead of
- Gas fermentation can be used without a further addition of CO2 would be necessary.
- the anaerobic bacteria contained in the gas fermentation plant C2 set CO2 as a carbon source and H2 as Ener ⁇ source, which makes order and produce the target molecules. Furthermore, they require CO for the production of some target molecules, whereby the demand for CO is significantly lower than for H2.
- the device 1 provides to provide a part of the necessary hydrogen 4 with the aid of an electrolyzer 3 and the CO by reforming of biogas 12. It is advantageous that the CO2 contained in the biogas 12 is made usable by a dry reforming.
- the reaction is a good way _ to take advantage of the high C02 content in the biogas 12 meaningful.
- This reac ⁇ tion the two main components of biogas CO2 and CH4 react with each other so that they are consumed. This is absolutely desirable for the CH4, as this can not be used in the Gasfer ⁇ mentation C2.
- this reaction is not enough to convert all CH4 because in all
- This reaction also has the advantage that it is exothermic and thus it can at least partially apply the necessary reaction enthalpy for the drying reforming.
- Another way to convert methane is steam reforming:
- reaction is exothermic and thus helps in addition to the partial oxidation, the reaction enthalpy for the dry and steam reforming apply. It is also advantageous that, in addition to the CO, CO2 is also required for the gas fermentation C2.
- the device 1 provides that a biogas 12, if necessary after a desulfurization, is reacted on a catalyst. It is hereby aimed that existing methane is completely implemented, which makes it necessary to add oxygen 5 and / or water 2.
- An autothermal reaction ⁇ tion leadership Cl is considered to be particularly advantageous since no additional heat source is needed in this and no cooling demand arises.
- the system aims contrary to the thermodynamic equilibrium, at reaching equilibrium a defined composition and a defi ⁇ ned temperature have set at the reactor outlet.
