Description
Technical field
The present invention relates under oxygen free condition, prepare the method for tung oil slag liquid biological energy source.
Background technology
Tung oil tree is an Euphorbiaceae tung tree plant, be one of China major industry oil plant seeds,, cultivated more improved seeds at the cultivation history in existing more than 1,000 year of China, in the extensively cultivation of China south, wherein Sichuan, Guizhou, Hunan, Hubei are the four big provinces that China produces tung oil.Tung oil tree seed expressed oil is tung oil, tung oil tree seed oil length 33%-71%, and the per mu yield of 10 years oil generation paulownias can be up to 45 kilograms.And tung oil is difficult for rotting, and its transportation and storage condition is without any restriction.Tung oil golden yellow color or pale brown look, it is good siccative oil, glossy, have waterproof, airtight, do not conduct electricity, characteristics such as antiacid alkali, protection against corrosion, cold-resistant heat, therefore in the industrial production such as system lacquer, plastics, electrical equipment, synthetic chloroprene rubber, imitation leather, synthetic petroleum, printing ink that are widely used in.Tung oil tree is the traditional exporting of China, accounts for 70% of Gross World Product.
The tung oil tree seed is called Chinese wood oil residule by the resistates that squeezing or method such as extraction prepare behind the tung oil, also claims that tung oil tree is withered, the tung oil dregs of rice, tung oil bran, tung cake, tung seed cake, tung pomace etc.Chinese wood oil residule contains amounts of protein and polysaccharide etc., can be made into plant protein fodder; The nitrogen of Chinese wood oil residule, phosphorus, potassium content are higher, therefore also can be used as efficient organic fertilizer.Yet the Chinese wood oil residule that China is a large amount of is developed so far as yet fully owing to lack industrial applications research, and the part Chinese wood oil residule is taken as fuel and burns, and the overwhelming majority goes out of use, and causes the great wasting of resources; Simultaneously, the Chinese wood oil residule that goes out of use easily goes mouldy rotten, produces poisonous solid, liquids and gases material, and severe contamination soil and water body environment are unfavorable for the sound development of tung oil tree industry.
Therefore, carrying out the comprehensive utilization and the high value added product exploitation of Chinese wood oil residule, is tung oil tree industry urgent problem.China is greatly developing particularly forest biomass energy of renewable energy source, and the liquid fuel of biomass transforms and utilization is one of its main mode.Tung oil is exactly good fuel oil among the people from ancient times, and residual in the Chinese wood oil residule more tung oil and other chemicals are arranged, therefore, Chinese wood oil residule is prepared into the value added applications scope that liquid biological energy source will further improve Chinese wood oil residule, can effectively reduces the wasting of resources and environmental pollution simultaneously.
Summary of the invention
It is simple relatively that technical problem to be solved by this invention provides a kind of operating procedure, and controllability is better, and cost is lower, do not need the preparation method of the tung oil slag liquid biological energy source of expensive device.
In order to solve the problems of the technologies described above, the preparation method of tung oil slag liquid biological energy source provided by the invention comprises the steps:
(1), Chinese wood oil residule is made 20 orders～80 purpose powder;
(2), under oxygen free condition, the Chinese wood oil residule powder is carried out the direct heat cracking, the thermo-cracking temperature is 180 ℃～890 ℃, and thermal cracking gas is carried out room temperature cooling, promptly gets pyrolysis oil;
(3), under 9-116 ℃, 0-0.96MPa vacuum, with the pyrolysis oil of Chinese wood oil residule separate, evaporation, after the evaporant cooling, promptly get tung oil slag liquid biological energy source, resistates is a solid state energy sources.
Chinese wood oil residule described in the above-mentioned steps 1 also claims that tung oil tree is withered, the tung oil dregs of rice, tung oil bran, tung cake, tung seed cake, tung pomace.
Chinese wood oil residule described in the above-mentioned steps 1 is meant by squeezing, extraction or both methods such as combine and prepares the formed oil cake of tung oil from the tung oil tree seed that the tung oil tree seed is meant the seed that derives from all tung oil tree kinds of tung tree.
Oxygen free condition described in the above-mentioned steps 2 is helium, carbonic acid gas, nitrogen one of them or arbitrary proportion mixture.
Room temperature described in the above-mentioned steps 2 is 8 ℃～32 ℃.
Adopt the preparation method of the tung oil slag liquid biological energy source of technique scheme, under oxygen free condition Chinese wood oil residule is transformed into liquid biological energy source, transformation efficiency is more than 56%.The liquid biological energy source of this Chinese wood oil residule is environmentally friendly, is with a wide range of applications at forest renewable energy source domain.Method operating procedure provided by the invention is simple relatively, and controllability is better, and cost is lower, does not need expensive device, and easily industrialization.
