Background technology
Environmental pollution, Global warming and energy shortage have made Sustainable development become the ultimate challenge that various countries, the world today are faced.In order to break away from gradually to the depending on unduly of oil, reduce greenhouse gas emission, many countries seek the substitute energy-renewable energy source of oil one after another.The research and development of the renewable energy resources is subjected to the whole world and pays close attention to, and the popularization of the renewable energy resources has become the direction of international energy policy.The renewable energy resources comprise biomass energy (biomass alcohol, biodiesel etc.), wind-force, sun power, underground heat, tidal energy etc., but present regeneration biological mass-energy source main raw material derives from cassava, sugarcane, Ipomoea batatas, sweet sorghum, corn etc., all be subject to yield poorly, all unfavorable factors such as cost height, do not meet the industrial development principles that country " does not strive grain with the people; do not strive ground with grain, promotes the energy and grain doulbe-sides' victory " yet.Thereby to utilize source non-grain raw material production biomass energy more extensive, the cheaper rich cellulose of cost be the direction of fuel industry development, and one of final solution of biomass energy can fundamentally realize the Sustainable development of energy industry especially.
Summary of the invention
Purpose of the present invention is exactly that a kind of not only method that provides for the deficiency that solves prior art is simple; can effectively reduce energy consumption; and can also improve ethanol production; realize extensive chemical industry production, help advancing the High Temperature High Pressure Mierocrystalline cellulose of Mierocrystalline cellulose alcohol industrialization process to change sugared technology.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of High Temperature High Pressure Mierocrystalline cellulose changes sugared technology, it is characterized in that it comprises the steps:
A, elder generation cut into the sheet plant fiber material with plant fiber material by slicing machine;
B, sheet plant fiber material are sent into rough grinding machine and are roughly ground, and produce the flocculence plant fiber material;
C, will roughly grind vegetable fibre, half fiber and add dilute sulphuric acid, and send into the steaming and decocting under high pressure jar with feeding machine;
D, boiling are finished vegetable fibre, half fiber and are entered fine grinder and wear into that sending into behind the pulpous state sizes mixing jar sizes mixing;
E, size mixing and by interchanger, condenser required temperature adjustment is finished after finishing, enter the saccharifying tank saccharification.
As further specifying of such scheme, in described processing step c process, the sulfuric acid amount that adds dilute sulphuric acid transforms each ton sugar by Mierocrystalline cellulose, hemicellulose, and sugar per ton adds sulfuric acid 2-5kg.
At described processing step c, in fiber, half fiber adding dilute sulphuric acid process, send into steaming and decocting under high pressure jar 3-15min with feeding machine, the temperature in the digester is 160-280 ℃, pressure is 1.5-2.5MPa; Send into fiber in the digester and half fiber at high temperature, high pressure, finish breaking and transforming of fiber and half fiber in the time.
In the process of sizing mixing of described processing step d, add starch (not needing boiling when adding starch), add amount of starch by producing ton sugar 80-200 kg, Ye Huamei 20ku/g produces ton sugar meter 0.5-1.5 kg.
At described processing step e saccharifying, add saccharifying enzyme 100 ku/g and produce ton sugar meter 1-2.5 kg, the saccharification liquid that comes out from saccharifying tank contains sugar 18-25% and sends into follow-up sweathouse.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, the present invention can effectively decompose xylogen and robust fibre in the vegetable fibre by grinding, steaming pressure, three processes of saccharification, helping cellulose conversion is fermentable sugars such as glucose, D-seminose, D-semi-lactosi, D-wood sugar and L-arabinose, help the follow-up fermentation and the operation of still-process, improve ethanol production.
2, the present invention can realize that high-level efficiency, high yield, low cost are carried out Mierocrystalline cellulose, hemicellulose is converted into fermentable sugar, has improved raw material greatly and has gone out sugared rate and liquid glucose quality, makes more biomass carbon change bioenergy into.
3, heat energy of the present invention repeats repeatedly to use and can effectively reduce energy consumption, and each step all can realize extensive chemical industry production continuously simultaneously, helps advancing Mierocrystalline cellulose alcohol industrialization process.
