Description
The present invention relates to a continuous saccharification apparatus of seaweed biomass which is being watched as a material of biofuel.
Biomass is a renewable organic material extracted from energy-only plants and forests, agricultural and feed crops, agricultural wastes and debris, forest wastes and debris, aquatic plants, animal waste, municipal wastes, industrial wastes, And organic materials that are currently used as energy sources. Such a biomass is a huge energy store that stores solar energy and if it can be effectively used, it will be able to easily solve the energy barriers caused by excessive use of fossil fuels. Such biomass can be used to cultivate as much energy as necessary Because it can prevent excessive accumulation of carbon dioxide in the atmosphere, it can solve the problem of global warming, which is an extremely serious problem today.
Bioethanol, one of the alternative energy sources using biomass, is extracted from plants such as sugarcane and corn. It can be mixed with gasoline or injected into automobile fuel alone. As bioethanol has emerged as an alternative energy source, demand for corn, sugarcane and wheat, which are raw materials, has soared, which is a factor in the surge in grain prices. As described above, the method of obtaining bioethanol from grains is not free from the criticism that the grain resources should be used as food for the hungry population as well as the above-mentioned problem of the sharp increase in the grain price, To the woody system, but the lignin system has not been able to find a breakthrough due to difficult process problems such as lignin removal
Recently, seaweeds have been attracting attention as a raw material for producing bioethanol. The algae are high in growth rate and can be mass-produced. They do not require separate fertilizer or agricultural water. They contain a large amount of sugar and alginic acid, so they are suitable for conversion to energy. The content of carbohydrates And is 1.5 to 2 times higher than wood-based raw materials.
In addition, since these seaweeds have a less dense structure than lignin, they are easier to saccharify than conventional biomass, and the yield is also very large. It also has great potential to utilize relatively abundant marine resources.
The present invention seeks to provide a continuous saccharification apparatus capable of easily saccharifying a large amount of seaweed biomass.
However, the problems to be solved by the present invention are not limited to the problems described above, and other problems not described can be clearly understood by those skilled in the art from the following description.
In order to accomplish the above object, one aspect of the present invention provides a fish processing apparatus comprising: a supply unit for supplying algae; A first pressure holding unit for supplying the algae introduced from the supply unit into the reactor while maintaining a constant pressure in the reactor; A catalyst reservoir connected to the reactor and storing a catalyst to be supplied to the reactor; And a second pressure holding part connected to the reactor and allowing the product obtained by the saccharification reaction performed in the reactor to be discharged to the outside while maintaining a constant pressure in the reactor. Thereby providing a saccharification device.
The present invention can effectively sacrifice a large amount of algae biomass by providing a pressure holding part that keeps the pressure in the reactor constant when the algae are fed into the reactor, by performing the saccharification process continuously. Also, the saccharification conditions of the seaweed biomass can be changed by adjusting the rotation speed of the screw in the reactor.

Thereafter, the algae introduced from the supply part is supplied to the first pressure holding part which supplies the inside of the reactor while maintaining the pressure in the reactor constant.
Conventional algal biomass glycosylation systems are batch glycosylation systems in which a seaweed biomass is fed to a batch reactor and the product formed by the glycosylation of the seaweed is fed to the batch reactor Extracting devices were common. The batch type reactor was able to maintain a constant pressure during the saccharification process, but it was unable to continuously supply the seaweed as a reactant, resulting in a low efficiency of the saccharification process and a large amount of time and labor.
On the other hand, according to one embodiment of the present invention, the saccharification process is continuously performed by connecting the feed section and the reactor through the first pressure holding section and supplying the algae into the reactor while maintaining a high pressure in the reactor . Accordingly, the glycation apparatus of the seaweed biomass of the present invention is a continuous glycation apparatus, and can easily sacrifice a large amount of seaweed biomass.
A catalyst supplied from the catalyst reservoir may be supplied to the reactor together with the seaweed supplied to the reactor via the first pressure holding portion. In one embodiment, the catalyst reservoir may additionally be connected to a means capable of regulating the concentration and amount of the catalyst supplied to the reactor, for example, a feed pipe, a valve, a flow meter or a high pressure metering pump, But is not limited to. In addition, the means for regulating and supplying the concentration and amount of the catalyst may also serve to maintain the pressure of the reactor constant when the catalyst is supplied to the reactor.
In one embodiment, the catalyst may include, but is not limited to, a hydrolysis catalyst and / or a hydrolase. The hydrolytic enzyme may be, for example, an amylase, a glucoamylase, an endoglucanase, a cellulase, a xylanase, a beta-glucosidase, a-agarase agarase, beta-agarase I, beta-agarase II, beta-galactosidase, neoagarobiose, neoagarotetraose, neoagarohexaose, neoagrohexaose, neoagrobiose hydrolase, and the like, but the present invention is not limited thereto. The hydrolysis catalyst is an acid or base hydrolysis catalyst, and any catalyst capable of forming a monosaccharide or a polysaccharide by saccharifying a seaweed can be used without limitation.
The reaction vessel of the present invention is connected to the first pressure holding portion and the catalyst reservoir, and the saccharification reaction is caused by the catalyst supplied through the catalyst reservoir through the first pressure holding portion. In one embodiment, the glycation process in the reactor can be carried out at a reaction temperature of 80 ° C to 200 ° C, a reaction pressure of 1 bar to 10 bar for 0.5 hours to 5 hours, but is not limited thereto.
The saccharification process is carried out by hydrolysis using the catalyst, for example, a hydrolysis catalyst and / or a hydrolase. In addition, the saccharification step may include direct saccharification using seaweed as a raw material, or indirect saccharification using raw materials such as cellulose and wool extracted and / or extracted from the seaweeds.
In one embodiment, a hydrolysis catalyst may be added to the seaweed supplied through the first pressure holding section to obtain only a single-stranded body, or both monosaccharides and polysaccharides may be obtained. At this time, the polysaccharide can be converted into a monosaccharide by hydrolysis again using a hydrolysis catalyst or a hydrolase. The monosaccharide or polysaccharide may vary depending on the type and composition of the seaweed biomass, and the polysaccharide may be selected from the group consisting of agar, cellulose, starch, carrageenan, alginic acid and fibrin But the present invention is not limited thereto.

The reactor may include a screw that transfers the seaweed supplied to the reactor by the first pressure holding unit in a predetermined direction in the reactor by a transfer driving force by axial rotation. The screw not only facilitates the movement of algae with high viscosity in a certain direction but also facilitates agitation of the algae and the catalyst to improve the efficiency of the saccharification reaction.
In one embodiment, the screw may further include a driving unit connected to an end of the screw to supply power to the screw, but the present invention is not limited thereto. The screw connected to the driving unit can adjust the moving speed and the movement amount of the algae by adjusting the rotation speed of the screw. The faster the rotational speed of the screw, the faster the moving speed of the seaweed in the reactor, the shorter the residence time of the seaweed in the reactor, and consequently the saccharification reaction time is shortened. On the contrary, the slower the rotation speed of the screw, the slower the moving speed in the reactor of the seaweed, and the longer the residence time of the seaweed in the reactor, the longer the saccharification reaction time becomes. The saccharification apparatus of the present seaweed biomass can control the degree of saccharification of the seaweed as a result of adjusting the rotational speed of the screw as described above.
Thereafter, the product obtained by the glycation reaction is discharged to the outside through the second pressure holding part connected to the reactor. The second pressure holding portion may include all of the contents described with respect to the first pressure holding portion, and redundant description is omitted for the sake of necessity.
The glycosylation device of the present seaweed biomass is not shown in the figure, but can be controlled by a control system connected to the device. The control system can control, for example, the rate of injection of algae, the rotational speed of the screw, the temperature and / or pressure in the reactor, the amount of catalyst supplied, and the like.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
