Definitions
- Raw materials for bioethanol production basically represent all plants that contain a correspondingly high content of fermentable substances.
- WO 1098041646 A1 mentions a process for utilizing biomass from agricultural crops, which is comminuted and compressed and separated into a low-solids phase and a solids-rich phase, the high-solids phase being treated with steam in overpressure.
- the final product is ethanol, pulp and biogas.
- carbonaceous material is to be converted into ethanol by a continuous hydrothermal treatment and without the addition of chemicals.
- the resulting liquid and fiber fractions should be separated after this pretreatment. It is stated that the final product is fuel ethanol, animal feed and electricity or electricity.
- the first solution of the problem comprises according to the invention a method for processing of grain and lignocellulose to bioethanol in a production line for grain and at the same time the production line for lignocellulose up to the saccharification stage and a specific fermentation depending on the biomass used is operated and then the streams into one common distillation and dehydration step.
- the biogas can be used for power generation and the use of electricity in the vicinity or the production lines or mixed with the natural gas or city gas via a low-pressure gas distribution network.
- the process of the invention is preferably carried out so that the lignocellulose is digested in the hydrolysis step so that the hydrolyzed mass has a largely neutral pH, preferably in the range of pH 5 to 7 by dispensing with the addition of acids or alkalis.
- the process makes it possible to feed the two co-operating bioethanol plants with variable amounts of cereals and lignocellulose-containing biomasses, the proportion of lignocellulose, based on the amount of cereal used, being from 1 to a maximum of 50% by weight. So it can, for example, deliver the grain and straw at the same job site of cereal farmers. On the other hand, any lignocellulosic biomass can be processed.
- the device according to the invention is designed so that both lines are coupled to a biogas plant for receiving vinasse from the distillation device and liquid phases from one of the hydrolyzing device for lignocellulose downstream separation device for solids and liquids.
- the invention is best illustrated by comparing the state of the art in widespread manufacturing processes for the recovery of ethanol from lignocellulose and from cereals, respectively, and contrasting them with the present inventive concept, described by means of diagrams of the production process.
- Figure 1 shows a biomass process developed by the "National Renewable Energy Laboratory, USA”: combination of steam pretreatment and mild acid hydrolysis of the hemicellulose fraction followed by enzymatic hydrolysis of the cellulose, with cellulose hydrolysis and fermentation of xylose and glucose monomers proceeding therein Fermentation organism is the genetically modified bacterium Zymomonas mobilis.
- Fig. 2 shows a biomass process developed by "BC International Corporation, Canada”: two-stage acid hydrolysis (first stage releases hemicellulose sugar, second stage cellulose-sugar),
- Figure 3 shows a biomass process developed by "Logen Corporation, Canada”: steam digestion with dilute acid for the release of the hemicellulose sugars and subsequent hydrolysis of the cellulose.
- the alcohol is separated (distillation) and further concentrated (dewatering) for
- Figure 5 shows the invention with the simultaneously and at one site operated in parallel plants for ethanol production from grain (upper part of the figure) or lignocellulose (lower part of the figure) and their linkage of the invention in a schematic process plan, which roughly divides the individual treatment stages.
- Wheat, corn, rye, triticale, barley, or sugar-containing raw materials such as sugar beet, potatoes, molasses, etc. can be used as the raw material.
- Cereal straw, wood, grass, bagasse, waste paper, green waste, etc. are used as raw materials containing lignocellulose.
- a farmer growing energy crops can supply both the threshed grain and the straw (fresh cornhoppers).
- the grain here for example triticale, with the highest possible starch and low protein content is first ground in a grinder. Depending on the raw material, the grain is reduced to, for example, a particle size of less than 1 mm. In contrast to the prior art, bran accumulating here is not screened out.
- the fermentation stage the fermentable sugar is converted into ethanol and carbon dioxide by adding yeast.
- This process lasts for 12-50 hours and provides a final ethanol concentration of, for example, 5.0-13.0, preferably in the range of about 4-19, weight percent.
- Parallel to the anaerobic fermentation a partial flow of the yeast is aerated aerobically in a side stream of another container, so that sufficient Hefezellsubstanz is formed. Thereafter, the biomass is conveyed to a distillation device.
- the abandoned biomass for example, straw, is using mills and
- Shredders shredded to a particle size of 0.5 - 10 cm.
- the shredded straw is suspended in a reactor by addition of water in a suspension, then by means of direct steam, without addition of chemicals and alkalis or acids, heated to 160-220 ° C, in
- the lignocellulose is digested in the hydrolysis step so that the hydrolyzed mass has a largely neutral pH, preferably in the range of pH 5 to 7.
- acids are released, which cause a slight pH drop, but should not and will not leave the said pH range.
- the mass is cooled to the desired saccharification temperature in two flash vessels connected in series.
- the steam thus obtained is used, for example, in the grain-based plant part as shown by a dashed arrow in FIG. 5.
- the use of the extracted steam elsewhere in this plant and in the grain line is also considered to be inventive.
- the saccharification is achieved by adding commercial cellulases.
- the residence time of about 48 h at the predeterminable temperature of about 40-60 ° C, depending on the type of enzyme used.
- the cellulose is enzymatically degraded into glucose monomers.
- the following process step is the fermentation; After saccharification, a standard Saccharomyces fermentation is carried out at 30-40 ° C, which ends in a final ethanol concentration of, for example, about 5% by volume. Specifically, because of the frequent rejection of genetically modified biofuels, no genetically modified material or microorganisms suitable for this purpose should be used here.
- the ethanol- ⁇ / vasergic mixture obtained is then concentrated in a rectification device to about 90 wt .-% ethanol.
- the solution is further concentrated to at least 99.0% by volume of ethanol by means of a further dewatering treatment, for example an entrainer distillation or by molecular sieve technologies or pervaporation.
- the so-called vinasse is taken off at the bottom of the mash column and fed to the biogas plant.
- the entire vinasse in the biogas plant is reacted with the hemicellulosic liquid phase from the lignocellulosic line into biogas.
- the resulting biogas will then continue to be used to generate electricity.
- the process from the biogas production can - as is well known - so discharged or be fed to another, aerobic treatment.
