Definitions
- the present invention relates to an industrial process for obtaining lower alcohols, preferably of less than three carbon atoms, in particular methanol and ethanol, from the energy from a high temperature solar thermoelectric plant, using as products of Heading coal and water vapor.
- the process of the invention allows lower alcohols to be obtained so that solar energy from a high temperature solar thermoelectric plant feeds all the procedural steps, providing both the necessary electrical energy for carry out the intermediate stages of the process as essentially the products involved in their different steps (H 2 , O 2 , water vapor and CO 2 ) from a wet ground coal feed, the by-products obtained in these different stages of procedure fed back to the process itself.
- This synthesis gas can be obtained in different ways, being currently the most widely used process to obtain the partial combustion of natural gas in the presence of water vapor or the partial combustion of mixtures of liquid hydrocarbons or coal, in the presence of water .
- the Lurgi Process called the low pressure process to obtain methanol from gaseous hydrocarbons, liquids or coal, is based on the following stages:
- This stage is where the difference in the process occurs depending on the type of feeding.
- the feed is natural gas
- it is desulfurized before feeding the reactor.
- Approximately half of the feed enters the first reactor, which is fed with medium pressure water vapor.
- partial oxidation of natural gas occurs.
- H 2 , CO, CO2 and 20% residual CH 4 are obtained .
- This reaction occurs at 780 ° C and 40 atm.
- the synthesis gas plus the residual methane leaving the first reactor is mixed with the other half of the feed (previously desulfurized).
- This gas mixture enters the second reactor, which is powered by O2. This comes from a plant to obtain oxygen from air.
- This reaction occurs at 950 ° C. If the feed is liquid or coal, it is partially oxidized by O2 and water vapor at 1,400-1,500. C and 55-60 atm.
- the gas thus formed consists of H 2 , CO with some impurities formed by small amounts of CO2, CH 4 , H 2 S and free carbon.
- This mixture then goes to another reactor where the synthesis gas is conditioned, eliminating the free carbon, the H 2 S and part of the CO2, leaving the gas ready to be applied to the methanol reactor.
- the synthesis gas is compressed at 70-100 atm and preheated. Then feed the methanol synthesis reactor together with the recirculation gas.
- the Lurgi reactor is a tubular reactor, whose tubes are filled with catalyst and cooled externally by boiling water. The reaction temperature is thus maintained between 240-270 ° C.
- Methanol in a gaseous state leaving the reactor must be purified. To do this, it first goes through a heat exchanger that reduces its temperature, condensing the methanol. This separates Then by means of a separator, from which gases are conditioned which are conditioned (adequate temperature and pressure) and recirculated. The methanol in liquid state that leaves the separator feeds a distillation column fed with low pressure steam. Methanol leaves the distillation tower under standard conditions.
- the catalytic synthesis takes place in a fluidized bed reactor, in which the synthesis gas enters through the base and methanol exits the top.
- the catalyst is thus kept fluidized inside the reactor, which is cooled by boiling water, obtaining steam that is used in other sectors of the process.
- distillation is carried out in two stages instead of in one as the previous case of the Lurgi process.
- ethanol For its part, the industrial production of ethanol is mainly based on the processing of biological matter, in particular certain plants with sugars.
- the ethanol thus produced is known as bioethanol.
- ethanol can also be obtained by chemical modification of ethylene, by hydration.
- bioethanol can be produced from a large number of plants, with a variation, depending on the agricultural product, of the yield between the fuel consumed and that generated in said process.
- Pretreatment can be a combination of crushing, pyrolysis and attack with acids and other substances. This is one of the factors that explain why ethanol yields are high for sugarcane, mediocre for corn and low for wood.
- the fermentation of sugars is carried out by microorganisms (yeasts or bacteria) and produces ethanol, as well as large amounts of CO2. It also produces other oxygenated compounds such as methanol, higher alcohols, acids and aldehydes. Typically fermentation requires about 48 hours.
- the oldest method of separating ethanol from water is simple distillation, but the purity is limited to 95-96% due to the formation of a low-boiling water-ethanol azeotrope.
- a first fraction is produced that contains mainly methanol, formed in secondary reactions, this is the only method admitted to obtain ethanol for human consumption.
- azeotropic distillation is applied in a mixture with benzene or cyclohexane. Of these mixtures, the azeotrope, formed by the auxiliary solvent with water, is distilled at lower temperatures, while the ethanol is retained.
- Another purification method currently used is physical adsorption by molecular sieves.
- Ethanol for industrial use is usually synthesized by catalytic hydration of ethylene with sulfuric acid as a catalyst.
- Ethylene usually comes from ethane (a component of natural gas) or naphtha (a derivative of oil). After the synthesis, a mixture of ethanol and water is obtained, which must subsequently be purified by any of the processes described above. According to some sources, this process is cheaper than traditional fermentation, but currently represents only 5% of the global ethanol production capacity.
- thermochemical processes As an alternative to biochemical processes for converting lignocellulosic biomass into bioethanol, ABNT (Abengoa Bioenerg ⁇ a Nuevas Tecnolog ⁇ a, Abengoa S.A.) has identified thermochemical processes as a potential technological route to transform biomass into ethanol.
- thermochemical processes are characterized because they do not require the action of microorganisms to transform raw materials, usually they work at higher temperatures and with the action of catalysts to enhance chemical reactions.
- Thermochemical processes provide the advantage of being able to use a wide range of raw materials, in fact, any material with a suitable identity or in carbon or can be processed in addition to thermochemical processes. processes can produce a wide range of products beyond ethanol.
- thermoq u ⁇ m i ca route is divided into two fundamental phases, a first stage of transformation of biomass into an intermediate product, synthesis gas, and a second stage of transformation of the intermediate product - synthesis gases - in the desired products.
- the initial transformation of biomass into synthesis gas is called gasification. It is a process that takes place at a very high temperature, between 800 ° C and 1,400 ° C typically, in which the biomass is transformed into a mixture of gases, mainly hydrogen and carbon monoxide.
- the synthesis gas generated from the biomass after being properly conditioned, is transformed by metal catalysts that convert the hydrogen and carbon monoxide present in the synthesis gas into a mixture of alcohols, in which the majority product is ethanol However, other products such as higher and oxygenated alcohols are synthesized.
- a carbonaceous material which, simultaneously, acts as a catalyst and collector microwave, subjected to radiation and microwave heating and comprising the microwave radiation and heating steps of the carbonaceous material with microwave until the reaction temperature is reached, preferably between 500 ° C and 1000 ° C, more preferably at 800 ° C ; passage of the starting gas mixture of CH 4 and CO2 through the above material maintaining the radiation and microwave heating, preferably between 500 ° C and 1000 ° C, more preferably at 800 ° C; and recovery of synthesis gas.
- ES 2 200 890 T3 refers to a procedure for the synthesis of methanol from hydrogen, carbon monoxide and carbon dioxide under pressure, where natural sulfur gas is still reformed and then reformer and then the synthesis gas from a methanol synthesis, characterized in that after the synthesis gas stream passes through the reformer, a lateral stream is guided to a methanol prereactor, the methanol produced in the prereactor, to which methanol synthesis of the methanol stream is supplied that part of the main stream, and a stream of untransformed synthesis gas is again supplied in the methanol prereactor, where in the area of this supply an additional synthesis gas is simultaneously introduced that compensates for the resulting loss.
- ES 2 087 424 T3 refers to a gasification process for the production of synthesis gas using solar energy, which comprises: producing a liquid dispersion of a particular carbonaceous material; provide a solar gasifying reactor with upper and lower regions adapted for the admission of highly concentrated solar radiation; associating said solar gasifier reactor with a system for high concentration of solar radiation adapted to produce an elongated focal zone of high temperature within the reactor; continuously injecting said dispersion into said upper zone of such solar gasifying reactor in the form of droplets or discrete jets and allowing the dispersion injected in this way to submerge inside by gravity through said elongated focal zone; and continuously evacuate the synthesis gas obtained as a product from said upper region.
- the object of the present invention is to make available a procedure that allows obtaining lower alcohols from solar energy from a high temperature solar thermoelectric plant so that this energy feeds from the energy point of view all the procedural steps, providing both the electrical energy necessary to carry out the intermediate stages of the process and essentially the products involved in its different steps (H 2 , O 2 , water vapor and CO 2 ) a From a wet ground coal feed, the by-products obtained in these different process stages are fed back to the process itself.
- the process of the invention allows the storage of solar energy in the form of lower alcohols, which in turn may constitute alternative fuels to fossil fuels or be transformed into industrial and / or domestic fuels, and, on the other hand, due to the reuse of the by-products obtained in the different stages of the procedure essentially eliminates the danger arising from the production of waste, thus being a particularly advantageous process from the environmental point of view and highly energy efficient .
- the process of the present invention is developed from the addition of wet ground coal to the system and water vapor from a high temperature solar thermoelectric plant, through various steps specified below, obtained with a adequate energy and chemical balance, by means of various catalytic synthesis reactions with the corresponding catalysts, the final products in the form of lower alcohols, preferably of less than three carbon atoms, which, optionally, they can be transformed into fuels according to suitable procedures well known in the art.
- the process of the invention is based on obtaining synthesis gas from an external supply of wet ground coal and solar energy obtained in a high temperature solar thermoelectric plant in the form of water vapor.
- the water vapor produced is used both per se, as a reagent in the corresponding catalytic reactors, for the development of the chemical reactions involved in the process, and for the generation of electric energy from a motor / turbine device and a dynamo / alternator type device.
- This electrical energy allows to carry out an electrolysis reaction, in an electrolytic tank for this purpose, from which oxygen is obtained, as a necessary product for the generation of synthesis gas, and hydrogen, as a reagent for the production of alcohols lower in the corresponding catalytic reactors.
- Figure 1 General scheme of the process of the invention according to a preferred embodiment thereof.
- the process for the industrial production of lower alcohols preferably of less than three carbon atoms, in particular methanol and ethanol, from energy and water vapor from a solar thermal power plant of High temperature, by adding wet ground coal, consists essentially of the following stages: 1. Gasification / pyrolysis in dual reactor
- the gasification and pyrolysis reactions of the wet milled coal are produced.
- Water vapor from a high temperature solar thermoelectric power plant is fed to a dual gasification / pyrolysis reactor in which it is previously charged, through a feed hopper, wet ground coal.
- the wet ground coal is partially oxidized by O2 from a later stage of electrolysis (stage 2), and water vapor (from the solar plant), in a gasifier provided inside the dual reactor.
- the gas thus formed basically consists of H 2 , CO, with small amounts of CO2, CH 4 , H 2 S and free carbon.
- a pyrolysis is carried out in the same reactor, essentially eliminating free carbon, H 2 S and part of CO 2 . Briefly, between 38 and 705 ° C, devolatilization and release of carbon and hydrogen occur, between 705 and 1480 ° C of C and H 2 O (g) and between 1480 and 1815 ° C of C and O 2 .
- suitable catalysts are arranged in the reactor so that the different reactions can take place, as well as the means necessary to maintain their integrity, such as refractory linings, insulating materials, cooling jackets, etc.
- the waste from this dual process is collected and stored for later reuse in other processes, for example in processes where ashes are used or for recycling in the form of fertilizers.
- the synthesis gas thus obtained is then subjected to a cyclone in order to remove any solid residue, and subsequently, this already cleaned synthesis gas is redirected to a new reactor (step 3).
- the synthesis gas obtained in step 1 is compressed and heated before being fed to a catalytic reactor to obtain methanol.
- the reactor can be, for example, of the Lurgi type, a tubular reactor whose tubes are filled with catalyst and cooled externally by boiling water, also coming from the solar thermal power plant.
- the reaction temperature is thus maintained between 240-270 ° C.
- suitable catalysts are arranged in the reactor, so that the reaction occurs at a temperature of 420 ° and at atmospheric pressure.
- the oxygen byproduct of the catalyzed reaction is then recirculated into the dual gasification / pyrolysis reactor of step 1.
- the alcohols thus obtained are stored in a storage tank for later use or are used for the production, for example, of industrial and domestic fuels.
