Definitions
- the present invention relates to the field of the chemical industry, and more specifically, falls within the process of hydrothermal carbonization of biomass. State of the art prior to the invention
- the hydrothermal carbonization process has been known since its description by Friedrich Bergius in 1913, and has been described in the literature, such as in Chem. Mater., 2007, 19 (17), 4205-4212 or in New J Chem., 2007, 31, 787-789.
- Ingelia is one of the first companies that has developed an industrial process of continuous hydrothermal carbonization, as described in Spanish patents ES 200803271 and ES200803272.
- the objective of the process is to revalue biomass from agribusiness, such as the skin of orange, the bones of olives and other remains of fruits and vegetables, as well as other types of biomass such as pruning and gardening. This type of biomass often has a high water content (for example 80% and even more) which prevents any other use in an economical way.
- a fatty liquid by-product is also obtained, which we call oil.
- oil has been generated from the skin of the orange, as well as from the pruning of the pine.
- the composition of said oil varies according to the biomass used and is still unknown as a consequence of the fact that, as indicated above, the Industrial development hydrothermal biomass carbonization process is still a relatively recent technology.
- the first chromatographic analyzes carried out indicate that they are composed of a mixture of more than 100 different chemical substances and the value of the oil is estimated at 0.50 euros per liter if used as fuel.
- the present invention aims to revalue the oils generated in the hydrothermal carbonization process or isolate compounds of a special value from them.
- biochemical products all oils, pure components or compounds extracted from the hydrothermal carbonization process or after a catalytic transformation. Description of the invention
- the present invention is based on the hydrothermal carbonization process (HTC process) of biomass, which is designed to polymerize the biomass to the maximum, obtaining a maximum hydrothermal carbon yield that can also be understood as solid biofuel.
- HTC process hydrothermal carbonization process
- the biomass composed of different components such as lignin, cellulose and / or hemicellulose
- This step is also called the monomerization phase.
- mono-sugars such as hexoses or pentoses are formed.
- Formed molecules during the monomerization phase they are dehydrated to form carbonyl compounds of the aldehyde group, such as, for example, furanic compounds, and more specifically, for example, 5-hydroxymethylfurfural or furfural.
- This phase is known as the polymerization phase and it reacts not only the aldehydric compounds, but also aromatic compounds (from lignin), unsaturated compounds and acidic compounds (for example, sugar degradation products).
- aromatic compounds from lignin
- unsaturated compounds for example, sugar degradation products.
- acidic compounds for example, sugar degradation products.
- the composition of a simple hydrothermal carbon obtained from glucose was analyzed by nuclear magnetic resonance. As a result, it was observed that 60% of said coal corresponds to an interconnected network of furnic units.
- copolymerized levulinic acid as well as aromatic rings. These aromatic rings, however, are less abundant, mainly because no real biomass has been used, but only cellulose.
- Patent ES239320 describes a method of hydrothermal carbonization of biomass, characterized in that it comprises feeding the biomass to a vertical inverted flow reactor through an ascent tube in which a monomerization process is initiated. At the same time, the formation of oils begins, as well as the evolution of gases, such as methane or CO 2 , from the natural decomposition of biomass. These gases ascend through the interior of the riser until they accumulate in the upper part of the reactor, from where they are evacuated, together with the saturated steam, into the pressure control tank.
- gases such as methane or CO 2
- the density of the biomass can vary and be less than or greater than that of water, once the monomerization stage has begun, the components derived from it tend to rise and float on the surface. This effect allows said compounds to remain close to the waterline, once they have reached the mouth of the riser, so that the reactor maintains a defined level of the solid-liquid phase and the upper part of the reactor comprises steam and gases of process.
- this phase the oils and other components that have formed during the monomerization polymerize and form a kind of resin or previous carbon state. Depending on the type of biomass and the process conditions, this phase lasts between 1 and 6 hours, and preferably between 2 and 4 hours.
- the preferred temperature range must be between 170 ° C and 230 ° C, preferably between 179.9 and 219.6 ° C and more preferably between 191.6 and 209.8 ° C; while, in the case of pressure, the preferred range is 8 to 28 bar absolute pressure, preferably 10 to 23 bar, and more preferably between 13 and 19 bar.
- the density of the solid compounds formed increases while, at the same time, the thermal activity decreases. As a consequence of these effects there is a decrease of the compounds, within the process water, towards the ripening zone.
- a method of this invention is the subject of this invention.
- for the extraction of biochemical products obtained from a hydrothermal carbonization process of biomass comprising feeding an aqueous mixture of biomass to a vertical reactor, preferably a vertical inverted flow reactor, through an ascent tube in which it takes place a monomerization process of the aqueous biomass mixture.
- This monomerization stage as described in patent ES2339320, can take place in the riser, located in the central part of the vertical inverted flow reactor, as well as at its mouth, just below the waterline, where they form the evaporations that are evacuated from the top of the inverted vertical flow reactor.
- the process for extracting biochemicals object of the present invention is characterized in that it comprises feeding an aqueous biomass mixture from a preheating tube of the aqueous biomass mixture to a vertical reactor with a defined flotation level and an area of accumulation of vapors and gases in its upper part, where said biochemical product extraction process is characterized by:
- the reactor may consist of a vertical inverted flow reactor with a riser inside it in which the monomerization of the aqueous biomass mixture, as described in patent ES2339320.
- the previous stage of preheating the aqueous biomass mixture can be carried out in at least one preheating tube surrounded by an outer jacket.
- the heating of the aqueous biomass mixture can be carried out by the circulation of a heat-carrying fluid through a jacket located on the outside of said preheating tube, by direct injection into said preheating tube of at least one saturated or superheated steam and / or by direct injection into said hot gas preheating tube.
- the heating of the aqueous biomass mixture can be carried out in the same vertical reactor.
- said heating can be carried out by direct injection of at least one saturated or superheated steam and / or hot gases into the tube of ascent of the inverted flow reactor and / or in the inverted flow reactor itself, below the waterline of the aqueous biomass mixture.
- saturated or superheated steam is introduced, its flow rate and the degree of steam overheating, it will be possible to regulate the amount of transfer and extraction of biochemicals in the vertical inverted flow reactor.
- the vertical reactor vapors can be condensed in at least one condensing equipment, for example a tubular heat exchanger with a cooling fluid inside the pipes, and / or in the jacket of the preheating tube located before the vertical reactor.
- the condensation of the vapors can be carried out at different levels of temperature and pressure, depending on the type of biochemical product you want to obtain.
- condensation zone preferably by means of flow regulation valves depending on temperature and / or pressure, gas separation equipment and condensate evacuation and conduction equipment.
- the condensate of vapors and biochemicals (which comprise oils, etc.)
- said condensate can be conducted to separation equipment, such as, for example, settling, centrifugation, filtration equipment, etc., where the oils are separated and biochemicals and entrained gases are extracted.
- separation equipment such as, for example, settling, centrifugation, filtration equipment, etc.
- the remaining condensates which comprise a mixture of different acids and water, can be chemically recovered and / or conducted to at least one condensate tank and, from there, can be fed back into the process.
- the subject of the invention is also the product or biochemicals obtained from said process, as well as the use thereof, for example, in recovery methods by catalytic transformation.
- this system It may be based on the system described in Spanish patent ES2339321.
- the system object of the present invention may additionally comprise at least one condensation system for the condensation of the vapors extracted from the vertical inverted flow reactor.
- the vapors and / or gases extracted from the vertical inverted flow reactor can be conducted directly from said reactor to one or more of the condensing equipment to accelerate the condensation of the vapors.

- the process begins in the storage hopper (1), from where a mixture of biomass starts towards the compression pump (3), in which it is compressed to a pressure of at least 13 bar, which it is the reactor pressure plus the pressure necessary to overcome the back pressure created in the path of the preheating tube (5) and the ascent tube (8). It is then transported along the preheating tube (5), until it reaches a temperature of about 180 ° C. After this heating stage, the mixture is fed to the vertical inverted flow reactor (7), 6 m long and 1 m in diameter, through the riser (8), which has a diameter of 20 cm and It is occupying 60% of the reactor height.
- the density of the solid compounds is high enough to begin their descent into the ripening zone (12), in which they remain for another 8 hours until their thermal activity It drops to practically zero.
- an evaporator device (27) in which part of the reaction product from the ripening stage (12) is heated and evaporated so that the gases generated are reintroduced to the vertical inverted flow reactor (7) through the valve (28) and the steam injection system to the reactor (25).
- This evaporator device (27) in turn comprises an external heat input system (c) to keep the temperature constant.
- the mixture of carbonized biomass and process water enters the cooling equipment (16), where its temperature is reduced to about 90 ° C. Finally, once cooled, the mixture is extracted through the decompression valves (17) and (19), passing through the intermediate flash tank (18), obtaining a product consisting of a liquid phase and solid particles of carbonized biomass .
- the vapors and gases generated and accumulated in the upper part of the reactor (10) are directed directly from the inverted flow reactor (7) to the regulation tank pressure (13).
- the gases from said pressure regulating tank (13) are sent to the heat exchanger (20) or to the preheating tube (5), which act as condensing equipment to accelerate the condensation of the vapors.
- the pressure regulating tank (13) is placed in parallel with respect to said condensing equipment, and sometimes it may run out of steam transfer.
- the condensate of vapors and biochemicals comprising oils, etc.
- said condensate is conducted to separation equipment (26), such as settling, extraction, distillation, centrifugation, filtration, etc. equipment, where oils and biochemicals are separated and entrained gases are extracted.
- separation equipment such as settling, extraction, distillation, centrifugation, filtration, etc. equipment, where oils and biochemicals are separated and entrained gases are extracted.
- separation equipment such as settling, extraction, distillation, centrifugation, filtration, etc. equipment, where oils and biochemicals are separated and entrained gases are extracted.
- the remaining condensates which comprise a mixture of different acids and water, can be chemically recovered and / or conducted to at least one condensate tank (21) and, from there, can be fed back into the process.
