Description

Separator for wood biomass saccharification reaction apparatus using a supercritical water having a double filter {SEPARATOR FOR TREATMENT DEVICE OF SACCHARIFICATING WOOD BIO-MASSES BY SUPERCRITICAL WATER WITH DOUBLE-FILTER}

The present invention relates to a wood biomass saccharification reaction apparatus using supercritical water, and more particularly, wood residues generated in the process of preparing monosaccharides by decomposing wood biomass into supercritical water can be separated through a separator. And a separator for a wood biomass saccharification reaction apparatus using a supercritical water having a double filter.

As is well known, bio-mass refers to a bioorganism including plants, cells, and animals that eat and live by photosynthesis of plants and microorganisms that receive solar energy.

Biomass resources include starch-based resources, including grains and potatoes, cellulose-based resources, including agricultural, aquatic products such as herbs, wood and rice straw, chaff, and sugar-based resources such as sugarcane and sugar beets, as well as livestock manure, carcasses and It has a variety of properties, including protein-based resources, including microbial mycelium.

At this time, in producing bio-alcohol by fermenting the sugar obtained by saccharifying the starch crop or fiber plant, barley or corn may be used as the starch crop, and wood and rice straw may be used as the fiber plant.

The saccharification process of woody biomass includes acid hydrolysis and biological enzyme saccharification.

Acid hydrolysis of wood biomass mainly uses sulfuric acid to break down the ether bonds between fibrin, such as glucose, mannose, galactose, xylose, arabinose, etc. As a method of producing monosaccharides, corrosion of the process equipment is a problem because the conversion rate of monosaccharides of wood biomass is high but a relatively high concentration of sulfuric acid should be used. In addition, the final product is present under the acid (중) conditions, there is a disadvantage that the neutralization process for the ethanol fermentation.

In addition, the enzyme glycosylation method of wood biomass is a starch-based glycosylation process that converts biomass composed of starch into glucose by amylase or glucoamylase and cellulase by degrading wood cellulose. It can be divided into the wood saccharification process that produces glucose.

However, starch-based saccharification process is relatively generalized, but enzymatic saccharification of wood biomass is still in the research stage due to the structural properties of wood. Cellulase is also expensive and the time for the saccharification reaction is very long. Economic feasibility is evaluated.

Therefore, in order to solve the above problems, it is necessary to study the wood biomass saccharification method using supercritical water.

Here, the supercritical fluid refers to a fluid that exists in a state in which each fluid has its own critical temperature and critical pressure. In this state, new fluids appear, unlike the general properties of each fluid at room temperature and normal pressure.

Therefore, the supercritical water reaching the supercritical state (Water) disappears the neutral characteristics of the water and shows the characteristic of the acid (Acid), and when returned to the normal temperature and normal pressure state, the acid properties seen in the supercritical state disappear.

Here, the time required for saccharification can be shortened by saccharifying the wood biomass by focusing on the properties of super-critical water, and since water is used as a decomposition medium, it is possible to use the conventional sulfuric acid hydrolysis method. It can solve a lot of problems of corrosion of process equipment.

On the other hand, the major constituents of woody biomass are generally made up of three components: cellulose, hemicellulose, and lignin. Therefore, these woody biomass is also referred to as Lignocellulose.

Unlike starch, such as Amylose, which is linked to the α-1,4 bonds of glucose, which can be broken down and absorbed in the body, cellulose, which is the most abundant component of lignocellulosic, has a stable β-1 structure of glucose. In addition, since it is connected by 4 bonds, it has a relatively strong structure that is difficult to decompose physically and chemically.

Therefore, it is very important to break down this stable structure while minimizing sugar loss in order to produce lignocellulosic saccharification liquid in the supercritical water oxidative decomposition device, and timely debris remaining after decomposition in the device in a timely manner. Filtering remains a challenge.

Lignin, on the other hand, is a hydrophobic polymer containing a large amount of aromatic compounds and having a complex structure of a large molecular weight. Lignin is thought to be produced by plants for the purpose of rejecting various types of biochemical attacks and approaches from the outside, that is, microorganisms such as fungi and invasion of insects. It is known to be the most difficult to decompose among the natural compounds.

In addition, lignin forms a covalent bond with hemicellulose, and hemicellulose is linked with cellulose through hydrogen bonding, and as a whole, hemicellulose is surrounded by hydrogen bonding around a linear cellulose microfibril. It is attached, and hemicellulose is surrounded by lignin through covalent bonds.

Lignin is a substance whose overall structure is irregular and its composition and binding form are not yet fully understood. It is a major cause of blocking the inside of the device when decomposing cellulose in the oxidative decomposition device using supercritical water to produce saccharified liquid. do. Therefore, like cellulose degradation products, degradation products of lignin also have a problem that must be removed from the inside of the device in the saccharification liquid production.

An object of the present invention for solving the above problems is to physically remove the wood residue in the separator, to prevent the inside of the device from being discolored by the wood residue to more stably to the monosaccharide which is a raw material of bioethanol from the wood biomass It is to provide a wood biomass saccharification reaction apparatus using supercritical water to produce.

The saccharified wood fraction (saccharified liquid + woody residue) can be obtained, including saccharified liquid.

The heat exchanger 70 recovers heat from the saccharified wood powder flowing from the reactor 50, and the recovered heat is reused in the preheater 30 or the line heater 40.

Then, the separator 80 is configured to separate the saccharified liquid by separating the wood residue from the saccharified wood powder flowed from the heat exchanger (70).

2 is an enlarged side cross-sectional view of the separator of FIG. 1, FIG. 3 is a plan view of the first filter plate of FIG. 2, and FIG. 4 is a side view of the strainer of FIG. 2.

2 to 4, the separator 80 includes a separation tank 86, a first filtering plate 88, and a filtering net 87.

Separation tank 86 is formed in a substantially cylindrical shape having an inner accommodating space, and is formed to have a sufficient inner accommodating space for separating the wood residue for saccharifying liquid extraction from the saccharified wood liquor introduced from heat exchanger 70.

The first filtering plate 88 is formed of a lattice disk having a predetermined mesh and is installed inside the separation tank 86 to divide the inner receiving space into the first space 83 and the second space 84. do.

In the present embodiment, the first space portion 83 and the second space portion 84 are partitioned in the vertical direction by the first filter plate 88, and the second space portion 84 is the first space portion 83. It is preferable to be partitioned below.

Meanwhile, an end portion of the inlet pipe 75 connecting the heat exchanger 70 and the separator 80 passes through the first space portion 83 and passes through the through hole 88a formed at the center of the first filter plate 88. It is connected to the second space portion 84 through, so that the saccharified wood powder is supplied from the heat exchanger 70 to the second space portion 84.

The drawing pipe 85 penetrates the separation tank 86 at one side of the drawing pipe 84 and is installed to connect the first space 83 and the storage tank 90 to the wood residue through the first filtering plate 88. The filtered saccharified liquid is discharged and stored in the storage tank 90.

Accordingly, the saccharified wood powder introduced into the second space portion 84 of the separation tank 86 through the inlet pipe 84 is filtered by the first filtering plate 88 and the first space portion 83 is filtered out of the wood residue. Saccharified solution introduced into the) to be discharged to the storage tank 90 through the withdrawal pipe (85).

In addition, the strainer 87 is installed to protrude in a mesh form at the inlet side of the withdrawal pipe 85 inside the first space 83 of the separation tank 86.

Here, the mesh of the sieve (87) is formed larger than the mesh of the first sieve plate 88, and serves to secondaryly filter the wood residue passing through the first sieve plate (88).

Referring back to FIG. 1, a second safety valve 71 is installed on an inlet pipe 75 connecting the heat exchanger 70 and the separator 80, and connects the separator 80 and the reservoir 90. On the withdrawal pipe 85, the negative pressure regulator 81 is installed so that the pressure inside the apparatus can be kept constant without lowering the saccharified solution.

Therefore, the wood biomass saccharification reaction apparatus using the supercritical water of the present embodiment, by filtering the wood residue through the separator 80 from the saccharified saccharification liquor through the reactor 80, the inside of the device is blocked by wood residue It is possible to stably produce monosaccharides, a raw material of bioethanol, from woody biomass.

Hereinafter, a part of the wood biomass saccharification reaction apparatus using the supercritical water according to the second embodiment of the present invention will be described with reference to FIGS. 5 and 6 attached thereto, and the same and similar parts as those of the first embodiment will be described. The same reference numerals are used and repeated descriptions are omitted.

5 is a side cross-sectional view illustrating a separator of a wood biomass saccharification reaction apparatus using a supercritical water according to a second embodiment of the present invention, and FIG. 6 is a plan view of the second filter plate of FIG. 5.

Referring to FIGS. 5 and 6, the separator 180 of this embodiment further includes an outlet 82 and a second filter plate 89 as compared to the separator 80 of the first embodiment. .

The discharge port 82 is formed in communication with the second space portion 84 at the lower portion of the separation tank 86, and withdraws the saccharified liquid that is not discharged through the withdrawal pipe 85 and filled inside the separation tank 86. Do it.

On the other hand, the outlet 82 may be further provided with an on-off valve (not shown) for controlling the amount of the saccharified liquid withdrawal and to prevent the pressure inside the device is lowered when the saccharified liquid is withdrawn.

In addition, the second filter plate 89 is formed in a disc shape having a predetermined mesh like the first filter plate 88 described above, and the first filter plate 88 and the discharge port are formed in the second space 84. It is provided to partition the space between 82.

Unlike the first filtering plate 88, the second filtering plate 89 does not have a through hole 88a formed in the center thereof, so that the wood residues filtered by the first filtering plate 88 are separated from the first filtering plate 88. It is stacked between the second filtering plate (89).

On the other hand, the mesh of the second sieve plate 89 is formed larger than or the same as the mesh of the first sieve plate 88, it is preferable to be formed smaller than the mesh of the sieve (87).

The mesh applied to the first filtering plate 88, the second filtering plate 89 and the filtering network 87 is the Korean Industrial Standard KS A 5101, and customarily in accordance with the Korean Law on Measurement and the Enforcement Decree and the Enforcement Regulations. Depending on the unit of mesh used in the British Inch standard (BS 40) and the United States (ASTM E11-61) standard, wood residues, that is, lignobiomass residues, are to be filtered out or not. The degree of particle size is according to the following Table 1.

In Table 1, the larger the number of meshes, the larger the unit scale number, and the smaller the grain size of the wood residues to be filtered.

Therefore, the mesh of the 1st filtering board 88, the 2nd filtering board 89, and the filtering net 87 can be suitably selected from Table 1 according to the unit scale | number number, and can be determined according to the order. .

On the other hand, the second filter plate (89) in addition to supporting the wood residue filtered between the first filter plate 88, when drawing out the saccharified liquid remaining in the separation tank 86 through the discharge port (82) It filters out woody residue.

As such, the saccharified solution in which the wood residue having a relatively large particle size is first filtered out of the saccharified wood powder drawn into the second space portion 84 of the separator 180 through the inlet pipe 75 is It flows into the first space portion 83 of the separation tank 86.

In addition, the wood residue having a relatively small particle size introduced together with the saccharified solution introduced into the first space portion 83 of the separation tank 86 is secondly filtered by the strainer 87 and then stored through the storage pipe 85. 90).

On the other hand, the relatively large particle size wood residue filtered by the 1st filtering board 88 accumulates between the 1st filtering board 88 and the 2nd filtering board 89 of the 2nd space part 84, and the strain screen 87 The relatively small particle size of the wood residues filtered by) are accumulated in the first space portion 83.

In this case, the second filtering plate 89 serves to support the wood residues filtered between the first filtering plate 88 and when the saccharified liquid remaining in the separation tank 86 is discharged through the discharge port 82. Filter out woody residue.

Hereinafter, the comparative experiment results of the wood biomass saccharification reaction apparatus using the supercritical water to which the separator of the second embodiment is installed and the separator without the conventional filter plate, respectively, will be described.

Experimental Example

As a sample used in this experimental example, wood powder, that is, lignocellulosic powder (Powder) was used.

In a typical experiment, the injection amount of the sample is 100 ml per minute, which is 50 ml of liquor cellulose powder mixed with 50 ml of lignocellulosic powder in 1000 ml of distilled water supplied from the distilled water tank 20, followed by preheating and The supercritical water 50ML having reached the critical state is passed through the reactor 50 in a supercritical wood powder (wood powder + supercritical water) state, respectively, mixed through a line heater.

That is, a flow meter or scale is installed in the sample tank 10 and the distilled water tank 20 at the same time, and the flow rate of the wood powder injected into the reactor 50 from the sample tank 10 and the distilled water tank 20 is reduced per minute. Normal operation time was performed for 40 minutes by making it total 100ML by 50ML.

Reactor (50) used a normal sliding type reactor and performed a catalyst-free reaction to measure pure wood residue.

Therefore, wood flour, that is, lignocellulosic powder decomposes and passes through the separator 80, and then passes through the sound pressure regulator 81 without a driving problem when the time is close to 40 minutes. Is considered to be normally separated inside the separator 80.

At this time, the flow rate of the fluid supplied from the sample tank 10 and the distilled water tank 20 is fixed to the dial (Dial Gauge) of the piston type compression pump (not shown) so that the desired constant flow rate is injected.

The supercritical wood powder passed through the reactor 50 was introduced into the separator 180 having the filter plate and the separator not installed with the filter plate, respectively, and the saccharified solution stored in the storage tank 90 was passed through the negative pressure controller 81. The time taken until was measured by comparison experiment.

On the other hand, the separator with no filter plate is applied to the sieve of the 200 mesh scale in the same way, so that the wooden residue, that is, lignocellulosic residue, directly enters the negative pressure controller 81, thereby avoiding the risk of blocking the device. .

In addition, in the separator 180 to which the filter plate is applied, the first filter plate 88 and the second filter plate 89 are applied to 180 meshes in the same manner.

The following Table 2 shows the production time, the amount of wood biomass input, and the residue in the separator, which take 4 L of saccharified liquid obtained by applying the conventional separator without the filter plate and the separator 180 with the filter plate, respectively.

In Table 2, in the case of the conventional separator without the filter plate, the time required to produce 4L of saccharified solution was 41.7 minutes on average, and the separator 180 having the first filter plate 88 and the second filter plate 89 installed thereon The average time was 39.3 minutes.

The dispersion value of decomposed residues of wood flour, ie, the weight of lignobiomass, into which both the separator without the filter plate and the separator 180 with the filter plate were put was not significantly different in the significance level, but in the case of the separator with the filter plate. The dispersion value of the time required for producing saccharified solution was smaller.

On the other hand, in the case of a separator installed with only one sieve mesh 87 of 200 mesh size, wood residue having a smaller size than the unit scale of the sieve 87 flows into the sound pressure regulator 81 as it is or with a saccharified liquid, or has a larger particle size distribution. If the residue blocks the periphery of the strainer 87, the normal saccharified liquid flow is disturbed.

In addition, the conventional sound pressure regulator 81 includes a backup-ring made of polytetrafluoroethylene (PTFE) material, an O-ring made of BUNA-N, and a chloro tree. 235 ± 5 ATM under pressure to reach a supercritical state while water, which is the medium of the reaction, adheres in order using a sheet of fluorotrifluoroethylene (CTFE) material in order to closely adhere to the path of the medium. The temperature condition was to endure 380 ± 5 ℃.

Therefore, when only pure saccharified liquid passes through the backup-ring, the O-ring, and the sheet of the negative pressure regulator 81 in sequence, and flows out to the final distal end, no serious problem occurs in operation. When a part of the wood residue inside the inflow into the sound pressure regulator 81, they are filled and fixed during long time operation, thereby preventing the normal saccharified liquid flow inside the sound pressure regulator 81.

When the flow of saccharified liquid in the supercritical water saccharification reaction unit starts to be disturbed, a problem arises in that the pressure rises instantaneously at 235 ± 5 ATM, and an additional reactor (50 The internal temperature rises and the carbonization occurs with lignocellulosic decomposition, accelerating the problem of clogging the conduit inside the reactor.

Therefore, as in the present embodiment, the separation plate (88, 89) is installed in addition to the sieve (87) inside the separator (80, 18) to remove the wood residue, that is, lignocellulosic residue from the saccharified wood powder By filtering, the amount of lignocellulosic residues introduced into the sound pressure controller 81 together with the saccharification solution can be reduced to increase the operating safety of the saccharification reaction apparatus of wood biomass using supercritical water.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications or changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. In addition, it is natural that it belongs to the scope of the present invention.
