Description

TECHNICAL FIELD [0001] The present invention relates to a multi-purpose biomass treatment apparatus for producing useful products derived from biomass, and a method for producing useful products using the biomass treatment apparatus,

TECHNICAL FIELD The present invention relates to a technique for treating biomass to obtain various useful products, and more specifically, to a biomass treatment method for treating biomass introduced in a single reactor to produce biomass-derived useful products including biomass pretreatment products, glycosylated products and bioethanol To a multipurpose biomass treatment apparatus for producing useful products derived from biomass and a method for producing useful products using the biomass treatment apparatus.

A number of techniques for biomass pretreatment have been studied for the purpose of producing a substrate that can be hydrolyzed quickly and efficiently to form fermentable sugars from biomass. Generally, the conventional biomass pretreatment processes include steam explosion, alkali treatment, sulfur dioxide treatment, hydrogen peroxide treatment, supercritical ammonia treatment, weak acid treatment, and ammonia freeze-thawing. Among these pretreatment methods, weak acid pretreatment methods and steam explosion pretreatment methods have been extensively studied and are now considered as excellent pretreatment methods. Both processes can effectively dissolve hemicellulose, but it is somewhat ineffective for lignin removal.

On the other hand, there are many problems in the enzymatic hydrolysis of the pretreated biomass. That is, the conditions necessary for the pretreatment of biomass are different from the optimal conditions for enzymatic hydrolysis. The enzymatic hydrolysis is usually carried out at a pH of about 4 to 6.5 and a temperature condition of about 30 to 55 ° C, but the biomass pretreatment method is generally too acidic and too hot compared to enzymatic hydrolysis conditions. The yeast-based enzyme reaction is typically carried out at a temperature of, for example, about 28 ° C to 40 ° C, and the thermophilic bacterium-based enzyme hydrolysis can proceed at a temperature as high as about 80 ° C and is based on mesophilic bacteria Enzymatic hydrolysis occurs at a temperature of about 20 째 C to about 45 째 C.

Moreover, conventional reactors used for continuous hydrolysis of the enzymes (in which there is an injection stream and a discharge stream and the reaction vessel is kept constant) require a large tank with an expensive and powerful impeller to mix the enzyme with the slurry , Enzymatic hydrolysis or liquefaction of biomass requires tens of hours (typically more than 24 hours) when mixed in large tanks.

In addition, the pretreated biomass must be cooled to a temperature suitable for enzymatic hydrolysis. For example, the pretreated biomass may be removed from the high temperature (e.g., 100 占 폚) to substantially the cooling system temperature (e.g., 20 占 폚 to 65 占 폚) during discharge of the pretreatment vessel prior to entering the reaction vessel for enzymatic hydrolysis Lt; 0 > C).

Due to these various problems, it is almost impossible to obtain a useful product with high efficiency by glycation and fermentation successively after pretreatment of biomass according to the conventional biomass treatment devices.

The first outlet 113a and the first inlet 114a are opened and the circulator 130 is operated to heat the supplied enzyme and the buffer solution to the reaction temperature to transport the enzyme and the buffer solution to the heat exchanger along the first connection member 150 The temperature inside the reactor is raised to the reaction temperature through a circulation process in which the enzyme and the buffer heated in the heat exchanger are re-transported to the reactor 110, and the pre-treatment biomass is subjected to glycation reaction while maintaining the reaction temperature through continuous circulation . After the saccharification reaction is completed, the first outlet 113a of the reactor 110 is closed, and a mixed solution containing an enzyme, a buffer solution, and a biomass saccharified product flowing through the first connection member 150 is supplied through the first inlet 114a The first inlet 114a is closed and the first opening and closing member 152 is closed and then the first outlet 113a is opened so as to obtain a final product through the first discharge member 151c, The final product can be recovered in the tank to yield a biomass saccharified product.

In some cases, when the washing of the pretreatment biomass is completed, the simultaneous saccharification fermentation reaction to the pretreated biomass washed in the reactor 110 can be performed (S7). The simultaneous saccharification fermentation reaction is carried out by opening the flow rate control valve 170 provided outside the enzyme storage tank and the buffer storage tank connected to the buffer storage tank in the reactor 110 in which the pretreated biomass is washed, A flow control valve 170 provided outside the injection port adjacent to the injection port connected to the yeast storage tank is also opened to supply the yeast to the reactor 110 at the same time as supplying the reaction temperature to the reactor 110, ), But the final product can be recovered to the final product-yielding tank to yield a biomass fermentation product, as described above, except that the fermentation temperature is set at a simultaneous saccharification fermentation temperature (about 40 degrees).
