Definitions
- the present application relates to a physically pretreated biomass composition capable of membrane filtration in a biomass solid-liquid separation process and a method for preparing a sugar therefrom.
- Lignocellulosic biomass consists of a hardly decomposable structure of cellulose, hemicellulose and lignin. In order to use lignocellulosic biomass as a sustainable source such as biofuels and biochemicals, it must be economically converted to useful intermediates such as sugar. Physical pretreatment, chemical pretreatment, and biological pretreatment suitable for lignocellulosic biomass properties can be converted into fermentable sugars.
- the pretreatment process is an essential step in converting lignocellulosic biomass to sugars, but has the highest operating cost of the overall process.
- the pretreatment process is a reaction between a solid biomass and a liquid (water, solvent or enzyme, microorganism), and washing and solid-liquid separation before and after each step are essential. That is, a typical process for the production of ethanol from biomass includes at least two solid-liquid separation steps.
- solid-liquid separation can be a key process step when biomass is used as raw material, which can be a major source of biomass pretreatment costs, and inefficient separation is negative for process economics and final yield.
- Membrane Filtration is widely used because it requires a relatively low energy input, has high selectivity, and can be simply used over a wide temperature range without the addition of chemicals (adjuvant). Membrane filtration is also suitable for solid-liquid separation / cleaning of biomass.
- Herbal biomass has a uniquely low density (below 0.2 g / ml), needle-shaped particles after physical pretreatment (milling), and inherent fibrils, causing membrane clogging during membrane filtration. Due to these characteristics, there are problems of increased investment cost due to over design of the solid-liquid separation system and increased operating cost due to short membrane replacement cycle. In addition, this clogging phenomenon has a problem in selecting centrifugation rather than causing frequent process troubles.
- One object of the present application is to provide a physical pretreated biomass composition comprising a particle size distribution wherein D10 is 1 to 10 ⁇ m, D50 is 10 to 30 ⁇ m and D90 is 30 to 120 ⁇ m.
- Another object of the present application is to (a) a pretreatment step comprising physical pretreatment of biomass; And (b) converting the pretreated biomass composition into sugars and solid-liquid separation by membrane filtration.
- the physically pretreated biomass composition of the present application has a specific physical pretreatment (attrition milling) of herbaceous biomass, thereby improving the passage speed without causing clogging during membrane filtration, thereby improving biomass solid-liquid separation process.
- Membrane filtration can be used, which is very useful for biomass processing processes.
- 1 shows a particle size distribution graph of an attribution milled biomass composition.
- FIG. 2 shows a particle size distribution graph of a grinder milled biomass composition.
- FIG. 3 shows a particle size distribution graph of a hammer milled biomass composition.
- FIG. 5 shows particle morphology of cornstalk biomass composition after physical pretreatment.
- FIG 6 shows the particle shape of the straw biomass composition after physical pretreatment.
- One aspect of the present application for achieving the above object provides a physical pretreated biomass composition comprising a particle size distribution wherein D10 is 1 to 10 ⁇ m, D50 is 10 to 30 ⁇ m and D90 is 30 to 120 ⁇ m. .
- biomass refers to a plant that synthesizes organic matter by receiving solar energy, and an organic organism such as an animal or a microorganism whose food is used, and in terms of ecology, all species or animals belonging to the bioorganism and
- a biomass is a representation of a species of plant in biomass within the unit area or volume of the habitat.
- biomass is generally irrelevant to life and death, and used in a broad sense. It includes firewood, charcoal, gas of living organisms, and the like, and organic waste is included in biomass in the industry.
- the biomass is largely classified into cultivation resources or waste resources biomass according to the raw material, and the cultivation resources biomass is derived from sugars, starches, celluloses, carbohydrates, fats and oils, freshwater, marine Systems, microbial systems, and the like.
- the biomass of the physically pretreated biomass composition of the present application may be a cellulose-based biomass including a tree-based, herbaceous and herbaceous biomass, specifically, but not limited to an herbaceous biomass.
- the term “herbaceous biomass” generally refers to rice plants, legumes, and residues thereof used for food or feed production other than trees grown on grassland.
- the herbaceous biomass is corn. It may be derived from a corn stover, wheat straw, straw, miscanthus sacchariflorus or rice straw, but is not limited thereto.
- pretreatment refers to a process that allows to improve the rate and yield of enzymatic hydrolysis of biomass.
- the ultimate purpose of the pretreatment is to reduce the crystallinity of the hardly decomposable structures such as cellulose, to increase the accessibility of the enzyme, and to increase the specific surface area of the biomass to increase the amount of the effective enzyme. Since production costs are determined, the pretreatment process is considered an essential step in converting biomass to biofuels.
- the pretreatment method can be largely divided into physical and chemical biological methods depending on the treatment method. Typical physical methods include milling or steam explosion, chemical methods such as dilute acid pretreatment, soaking in Aqueous Ammonia (SAA) and ammonia recycled leach. Percolation, ARP), and biological methods include methods using microorganisms such as molds.
- the physical pretreatment method in the present application may be the milling of the biomass, the milling of the attrition milling, grinder milling, hammer milling or cutter milling ( One or more milling processes of the cutter milling may be performed.
- the physical pretreatment may include, but is not limited to, an attrition milling process using an attrition mill.
- the biomass composition may mean the physical pretreatment, and may then provide a composition suitable for membrane filtration in a solid-liquid separation process.
- the average particle size and particle size distribution of the attrition mill treated biomass composition are significantly lower than those of the physically pretreated biomass composition, so that the passage speed is high during membrane filtration.
- the term "particle” refers to the size of the granular material, and unlike the particle size (particle diameter) which usually indicates the size of the particle as a diameter, the particle size also includes an indirect indication such as a specific surface area. Doing. In the case of a perfect sphere, a simple relationship is established between the particle diameter and the other particle size, but in general, the particle size is difficult to determine in one word, and the average diameter (mean value of the length in two or more directions) or the equivalent diameter (polyhedra As a representative representative length, assuming a simple shape).
- the particle size distribution may be measured by measuring the minimum size, the maximum size, the average value of the sample using a particle size analyzer to determine the distribution of the particles.
- the particle size distribution of the sample cannot be accurately determined only by the average value of the particle size, so that the particle size values corresponding to 10%, 50%, and 90% for the largest particle size in the cumulative distribution of the particle size are D10, D50, and D90, respectively. If the particle size distribution curve is defined based on the above values, the particle size distribution of the sample can be accurately represented.
- D10 may be 0.5 to 20 ⁇ m, 0.5 to 15 ⁇ m, 0.5 to 10 ⁇ m, 1 to 20 ⁇ m, 1 to 15 ⁇ m or 1 to 10 ⁇ m
- D50 may be 5 to 40 ⁇ m, 5 to 35 ⁇ m, 5 to 30 ⁇ m, 10 to 40 ⁇ m, 10 to 35 ⁇ m, or 10 to 30 ⁇ m
- D90 may be 20 to 130 ⁇ m, 20 to 125 ⁇ m, 20 to 120 ⁇ m, 30 to 130 ⁇ m, 30 to 125 ⁇ m or 30 to 120 ⁇ m, but is not limited thereto.
- the average particle size of the physically pretreated biomass of the present application is specifically 5 to 80 ⁇ m, 5 to 70 ⁇ m, 5 to 60 ⁇ m, 5 to 50 ⁇ m, 10 to 80 ⁇ m, 10 to 70 ⁇ m, 10 to 60 ⁇ m, 10 to 50 ⁇ m or 15 to 50 ⁇ m, but is not limited thereto.
- the physically pretreated biomass composition through the attrition milling treatment has a low average particle size and a narrow particle size distribution, which is different from the physically pretreated biomass composition. Can be increased.

- D10, D50, and D90 are the particle sizes of the points where the cumulative curves are 10%, 50%, and 90%, respectively, when the cumulative curve of the particle size distribution is obtained with 100% of the total weight.
- Flux was measured to evaluate the passage rate in MF treatment of physically pretreated herbal biomass. Specifically, 20 g of the physically pretreated biomass composition and 300 g of water were mixed, and then reacted at 90 ° C. for 1 hour, followed by solid-liquid separation using MF (F1091, 47 mm, chm by CHMLAB GROUP, USA) and a flat membrane module. Flux was measured using the amount of liquid passing through MF for 10 minutes to confirm the MF passing performance of the physically pretreated biomass composition (Table 4). In addition, 40 g of the physically pretreated biomass composition and 200 g of water were mixed, and then reacted at 190 ° C.
- the attrition milling composition under both conditions did not cause clogging when passing through the MF, it was confirmed that the MF pass flux is higher than the grinder, hammer, cutter milling composition. Therefore, it was confirmed that the use of the attrition milled biomass composition of herbal biomass resulted in a significant increase in treatment speed due to no MF clogging phenomenon during solid-liquid separation after chemical pretreatment, so that MF can be used in the biomass process.
