Abstract
The invention belongs to the field of preparing ethanol, phenol, toluene and the like by utilizing straw plants, and particularly relates to a method for extracting glucose and/or xylose for preparing ethanol by utilizing straw plants such as rice straws and the like. Mixing the straws and the dilute acid solution at room temperature according to the weight ratio of the straw plants to the dilute acid solution of 1: 4.5-8.5, heating to 90-100 ℃, keeping the temperature constant, rapidly hydrolyzing hemicellulose in the straws, extracting sugar solution, and fermenting the sugar solution to prepare ethanol. The sugar solution can be further added with cellulase to hydrolyze undissolved cellulose in the sugar solution. When the hemicellulose in the straws of rice straws and the like is hydrolyzed by dilute acid, the sensitivity of the fibers in the straws of rice straws and the like to cellulase is improved.
Description
Technical field
The invention belongs to and utilize the stalk plant to prepare fields such as ethanol, phenol, toluene, specially refer to the method with glucose and/or wood sugar such as the straw plant extract system ethanol that utilizes straw.
Background technology
Main chemical compositions is xylogen, hemicellulose, Mierocrystalline cellulose (the 6th page of the vegetable fibre chemistry third edition in the stalk plant; China is through industrial press) hemicellulose, cellulose degradation are become glucide (but prepare liquid fuel ethanol), lignin conversion based on wood sugar, glucose is that the industrial chemicals and the energy are one of desirable approach of higher value application stalk plant.
The domestic utilization extracted the existing history for many years of fiber papermaking in the stalk plants such as straw, wheat straw, reed.Because problems such as the pollution in the sepn process, pollution difficult treatment, expense height, be forced to stop production in a lot of paper mills, and a large amount of stalks go out of use, and cause the pollution (" vegetable fibre chemistry " China Light Industry Press 2001.1 third editions) of environment equally.
The utilization of the renewable matter of plant has several different methods, and the researcher that has (ProcessBiochemistry 37 (2002) 937～941) earlier with the xylogen alkali dissolution, has improved the susceptibility of Mierocrystalline cellulose to enzyme, and the plain enzymic hydrolysis of reprocess fibre prepares glucose; People (Enzyme and Microbial Technology 24 (1999) 667～674) under＞160 ℃ condition is also arranged, and is glucose with the plain enzyme liberating Mierocrystalline cellulose of reprocess fibre behind the processing stalks such as sulfuric acid, hydrochloric acid, alkali.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing stalk plant extract system ethanol such as straw with glucose and/or wood sugar.
The present invention utilizes the method for stalk plant extract system ethanol with glucose and/or wood sugar:
Under the room temperature, according to the stalk plant: the weight ratio of dilute acid soln is that 1: 4.5～8.5 ratio is mixed stalk with dilute acid soln, be warmed up to 90～100 ℃ of constant temperature then, hemicellulose in the quick hydrolyzing straw, extract sugar soln (with the straw be example sugar extraction yield be the straw nt wt net weight 15～20%), sugar soln is used for alcohol prepared by fermenting.This sugar soln is based on wood sugar basically, is outside the main sugar soln extracting wood sugar, and this method also effectively raises the susceptibility of stalk inner cellulose such as straw to cellulase.
In the above-mentioned sugar soln of preparing, can further add Mierocrystalline cellulose not molten in the cellulase hydrolysis sugar soln (is that example sugar extraction yield can be enhanced about more than once with the straw), wherein, the add-on of cellulase and the weight ratio of stalk are 1: 10～1: 100, with yellow soda ash, lime carbonate, sodium hydroxide or their adjust pHs such as mixture 4.5～5.5, be warmed up to 45～60 ℃ then, obtain containing the aqueous solution of glucose and wood sugar, sugar soln is used for alcohol prepared by fermenting.
Described dilute acid solution is the aqueous solution of dilute sulfuric acid aqueous solution, diluted hydrochloric acid aqueous solution or sulfuric acid and mixed in hydrochloric acid.Dilute acid concentration 0.5～1.5wt%.
Stalk of the present invention comprises straw, wheat straw, reed, cornstalk, beanstalk etc.
The present invention utilizes hemicellulose, Mierocrystalline cellulose in the stalk plant to put forward sugar preparation alcoholic acid method, has following characteristics:
One. the method for stalks such as dilute acid hydrolysis straw
1. prepare the sugar soln that contains wood sugar and glucose with the hemicellulose in the stalks such as dilute acid hydrolysis straw.
2. with in the stalks such as dilute acid hydrolysis straw hemicellulose the time, improved in the stalks such as straw fiber to the susceptibility of cellulase.
