Description
Technical field
The invention belongs to the biomass energy field, relate in particular to a kind of biological enzyme and produce 2 in stalk (rice straw, maize straw, wheat stalk) resource, the utilisation technology in the 3-butyleneglycol clean fuel.
Technical background
2,3-butyleneglycol fuel can be inexhausted as renewable energy source, and can not cause Greenhouse effect.Microbial fermentation sugar can produce 2,3-butyleneglycol fuel.In industrial production, be used for fermentation at present and produce 2, if the microbial host bacterium-klebsiella (Klebsiella) of 3-butyleneglycol or Bacillussubtilis genus (Bacillus) etc.The biomass that contain glucide that comprise stalk all may be as 2, the raw material of 3-butyleneglycol fermentation, and the utilization of macromolecular substance needs the degraded of process enzyme earlier.Biology 2,3-butyleneglycol are as the surrogate of oil, and its industrial chain is also continuing extension.There is development Mierocrystalline cellulose system 2 in China, the favourable condition of 3-butyleneglycol, every year, only rice straw just had more than 300,000,000 ton (dry weight), and China's grain resource is not abundant, therefore agriculture and forestry organic waste material is converted into 2,3-butyleneglycol fuel, the formation industrialization utilizes, be fit to very much the national conditions of China, also be very favourable from the energy security angle, and can eliminate the environmental problem that causes by crop straw burning.
Existing stalk (rice straw, maize straw, wheat stalk) resource produces 2, and no matter the cleaning technique of 3-butyleneglycol fuel as being raw material with full stalk, adopt acid hydrolyzation or enzymolysis process to produce 2,3-butyleneglycol clean fuel; Wherein a large amount of hemicelluloses, xylogen and ash content remain in the fermented liquid, bring the difficult problem of follow-up liquid waste disposal to be difficult to so far solve.
Summary of the invention
The objective of the invention is with paper industry after alkalizing or the Mierocrystalline cellulose that obtains of liquefaction process be main raw material, handle through biotechnology, produce biological cheaply 2,3-butyleneglycol fuel.Though and the present invention is characterized in that it selects stalk for use is raw material, but wherein a large amount of hemicellulose, xylogen and ash separation gone out by alkaline process or liquefaction process, and the Mierocrystalline cellulose (hexosan) that obtains is converted into glucose, insert bacterium-Klebsiella (Klebsiella) or Bacillussubtilis and belong to (Bacillus), the fermentation of saccharification limit, limit carries out 2, the 3-butyleneglycol is produced, and fermentation ends extracts 2 through underpressure distillation, 3-butyleneglycol and obtain novel clean fuel.Use grass to replace provisions, turn waste into wealth, reduced by 2,3-butyleneglycol production cost; Have only a spot of residual hemicellulose, lignin and ash content in the waste liquid, even the raw water hydrolysis and fermentation is incomplete, solid-liquid separation is easy in the waste liquid, and is also recycling, therefore reduced environmental pollution.This 2, the production of 3-butyleneglycol fuel has the low characteristics of production cost, playing exploit natural resources the protection environment double effects.The present invention adopts solid state fermentation, thereby has reached the purpose of water saving.
The objective of the invention is to realize by following technical proposal:
