Abstract
The invention belongs to the technical field of organic matter decomposition, in particular to a method for efficiently decomposing a macromolecular organic compound. The macromolecular organic compound can be decomposed through treatment under a closed environment at a saturated humidity, a temperature of not lower than 180 DEG C and the pressure of not lower than 18MPa. The method can realize efficient decomposition of the macromolecular organic compound; and materials obtained from the decomposition can be used as nutrients of animals and plants without causing further pollution, and can be recycled.
Description
(1) technical field
The invention belongs to organism decomposition technique field, particularly a kind of method of efficiently decomposing macromolecular organic compound.
(2) background technology
In the modern life, macromolecular organic compound is extensive use of.The rubbish that these materials use the back to form is very difficult to dispose, and at present, generally the method for Shi Yonging mainly is to burn, bury etc., but these methods of disposal have formed secondary pollution to atmosphere, soil and water.From the angle of environmental protection and Sustainable development, study a kind of simple and macromolecular organic compound decomposition method environmental protection and be necessary very much.
(3) summary of the invention
The object of the present invention is to provide a kind of method of efficiently decomposing macromolecular organic compound, can overcome the defective that existing treatment process is easy to generate secondary pollution.
The technical solution used in the present invention is as follows:
A kind of method of efficiently decomposing macromolecular organic compound is under closed environment, in saturated humidity, be not less than 180 ℃ temperature and be not less than under the pressure of 18MPa macromolecular organic compound is handled.
Treatment time generally is controlled to be 60-75min.
Described temperature generally is controlled to be 180-240 ℃, and pressure is 18-24MPa.
Further, described macromolecular organic compound is protein, fat or polysaccharide, and Controllable Temperature is made as 180-200 ℃, and pressure is 18-20MPa.
Described macromolecular organic compound is the high molecular polymer except protein or polysaccharide, and described temperature is 200-230 ℃, and pressure is 20-23MPa.
Present method adopts High Temperature High Pressure to decompose under the condition of saturated humidity to macromolecular organic compound, provide sufficient energy to break the intermolecular chemical bond of macromolecular organic compound, can be decomposed to form the small molecules polymkeric substance after the processing, as the nutrient of animal and plant, for garbage as resource provides an effective way.For example become glucose behind the amylolysis, the protein decomposition obtains amino acid, and the grease decomposition obtains higher fatty acid and glycerine or higher alcohols, and superpolymer decomposes acquisition gac and water.
The present invention has following advantage with respect to prior art:
The inventive method can realize the efficient decomposition of macromolecular organic compound, and the material that decompose to obtain can be used as vegeto-animal nutrient, not only can not cause further pollution, can also resource reutilization.
