Definitions
- the present invention relates to a continuously operated process for processing hydrocarbons into chemical products of value or liquid fuels.
- the hydrocarbons used are preferably methane, natural gas or biogas.
- the process also utilizes carbon dioxide derived from stationary or non-stationary equipment, the process being based in part on the use of renewable energy sources.
- the process is operated by means of a suitable process control partly through the use of process energy, which is released as heat energy in individual process steps.
- the process also relates to dry reforming, steam reforming, and partial oxidation, whereby a defined synthesis gas is obtained, which is converted into value products by the process (for example by FT (Fischer Tropsch) or methanol synthesis).
- FT Fischer Tropsch
- methanol synthesis a defined synthesis gas
- predominantly strongly endothermic reactions are carried out during daytime operation and predominantly exothermic reactions during nighttime operation, whereby, however, an excess amount of energy recovered during nighttime operation is used to maintain the endothermic reactions.
- the process can be carried out very energy efficiently, which means that the process minimizes the production of carbon dioxide.
- carbon dioxide is a very inert compound and a high energy barrier has to be overcome in order to react carbon dioxide.
- the carbon dioxide generated during energy production or chemical processes is considered a waste product and emitted into the atmosphere.
- the emission of carbon dioxide into the atmosphere such as the combustion of fossil fuels in stationary (such as power plants) or transient plants (such as automobiles) is due to the properties of carbon dioxide as a greenhouse gas and its Contribution to global climate change is highly undesirable. Minimizing the emission of carbon dioxide into the atmosphere is a key objective to reduce or prevent the negative effects of climate change. There are already methods for preventing or reducing the emission of carbon dioxide into the atmosphere.
- DE 3933285 discloses a process for the continuous production of synthesis gas by the solar reforming of methane, wherein the night cycle is operated by means of an auxiliary firing using methane and the resulting carbon dioxide for the CO 2 reforming is cached. A coupling of the process with steam reforming is not mentioned. In the process, only a syngas having a very high carbon monoxide content is obtained. The use of released heat of reaction, which results from the partial oxidation of methane or in the subsequent reaction of the synthesis gas is not described.
- US 4,668,494 discloses a chemical synthesis process involving steam reforming of hydrocarbons or gasification of carbonaceous fuels which can be operated using solar energy.
- the solar energy is used to produce a CO-free ammonia synthesis gas that can be burned to generate energy in the plant phase of the plant, where there is no solar radiation available, to sustain the process.
- the process produces nitrogen oxide-containing combustion products, which must be collected as nitric acid.
- One of the objects of the present invention was to develop an economical process for converting carbon dioxide derived from stationary industrial plants or transient plants such as vehicles into value products.
- the implementation of carbon dioxide should, if possible, be based on renewable energy sources and at the same time integrated into a process that is as continuous as possible.
- the reactions dry reforming, steam reforming and partial oxidation are combined, the endothermic steps are operated by means of or with the aid of renewable energy sources.
- the regenerative energy source is solar energy.
- the process has several distinct operating conditions, consisting essentially of intermittent (i) daytime operation and (ii) nighttime operation, daytime operations mainly involving dry reforming and steam reforming with the supply of regenerative energy and night-time operation. (ii) mainly involves the partial oxidation of hydrocarbons.
- the method includes the reaction of the synthesis gas produced to give value products, wherein the heat of reaction generated in this case is also partially used for carrying out the endothermic process steps.
- daytime operation and nighttime operation refer to the process operation in connection with regenerative energy sources (such as wind or sun) which are available only in certain periods of time, during which ges worries the regenerative energy source is usually available. It is by no means excluded that operating states occur which form an intermediate state between the daytime operation and the nighttime mode, if the availability of a power source during the daytime operation is not fully realized.
- regenerative energy sources such as wind or sun
- the process steps dry reforming of carbon dioxide, steam reforming and partial oxidation are carried out with short-chain hydrocarbon compounds having less than five carbon atoms and preferably less than three carbon atoms.
- the reactions dry reforming of carbon dioxide, steam reforming and partial oxidation are carried out with gas mixtures containing a plurality of hydrocarbon compounds which have a very high methane content.
- gas mixtures containing a plurality of hydrocarbon compounds which have a very high methane content This makes it possible, in the method which may comprise a plurality of operating states, to produce a synthesis gas having a defined overall composition with respect to the carbon monoxide to hydrogen content.
- the most preferred composition of the synthesis gas has a carbon monoxide to hydrogen content of 1 to 2 (CO / H2 equal to 1: 2), since such a composite synthesis gas is a suitable starting point for the production of value products.
- the method is carried out using solar energy sources. This results in a pronounced differentiation between the operating states daytime operation and nighttime operation.
- daytime operation the strongly endothermic reactions, dry reforming and steam reforming, are preferably carried out, and during night operation the partial oxidation, which takes place exothermically, is preferably carried out.
- the exothermic reaction can also be carried out in part in such a way that the heat released can be used to operate the endothermic reactions.
- cached excess hydrogen is burned or cached energy used for the process.
- the process according to the invention is preferably operated in a region in which solar energy is available in sufficient quantities throughout the year.
- solar Energy means the terms daytime operation (operation in the hours with sufficient solar radiation for the process operation) and nighttime operation (operation in the hours with insufficient sunlight for the process operation) also mean that the different operating phases preferably take place within a 24-hour day.
- the process is carried out in such a way that the synthesis gas has the desired composition so that it can be converted into value products in the further process stage. If there should be operating phases in the process in which a synthesis gas is produced with a composition which should not correspond to the desired composition for carbon monoxide to hydrogen for further processing, then this can initially be stored in a storage tank. By increasing the contribution to the steam reforming compared to the dry reforming a hydrogen-rich is fed to the storage tank until the synthesis gas has the desired ratios between carbon monoxide and hydrogen.

- a further possibility according to the invention is the use of a single reactor system in which the dry reforming and the steam reforming are carried out simultaneously or alternately with the aid of one or more catalyst systems, whereby a synthesis gas having a desired ratio of carbon monoxide and hydrogen is set and obtained can.
- a synthesis gas having a preferred stoichiometry in the sense of the present invention can be produced, ie a ratio of carbon monoxide to hydrogen of 1 to 2 (CO / H 2 equal to 1: 2), for further use in, for example, production of methanol or diesel fraction according to the Fischer-Tropsch process.

- the method according to the invention is carried out with the involvement of solar energy, since sufficiently high temperatures can be provided by means of solar energy for carrying out the chemical reactions and individual process steps.
- the syngas can also be produced by the partial oxidation of natural gas or other paraffinic gases according to the general formula:
- reaction of the partial oxidation thus represents a possibility for the production of hydrogen-rich synthesis gas during the time in which no or insufficient solar radiation is available.
- the dry reforming of carbon dioxide and the steam reforming may be carried out in a combined reactor system or several separate reactor systems, these reactors being fed with solar energy.
- the solar energy can be used directly as radiant energy for heating the reactor or be supplied by media such as gases, liquids or melts of, for example, salts or metals that have been heated using solar energy.
