Description
Technical field
The present invention relates to a kind of method that under oxygen free condition, prepares the draft oil slag liquid biological energy source.
Background technology
The draft oilseed plant is the important cash crop of China, and is in China's extensively plantation of most of area, huge to relevant industries influences such as the agricultural of China, industry, oil plants.The main application of draft oilseed plant is to utilize preparation oil plants such as its seed, seed or embryo, and this oil plant also is called the draft oil plant, has higher economic value, and is closely bound up with people's life, for significant contribution has been made in the development of China's agricultural and related industries.Particularly Viscotrol C, sesame oil, oleum lini, Oleum Helianthi, corn wet goods draft oil plant occupy an important position.The draft oil cake is draft oil grain, seed or embryo etc. by squeezing, extraction or both remaining resistatess behind the method system oil such as combine, and also can be described as the dregs of rice, bran, oil cake, slag etc.The draft oil cake generally contains amounts of protein and polysaccharide etc., can be made into plant protein fodder preferably; Constituent contents such as the nitrogen of draft oil cake, phosphorus, potassium are generally higher, therefore also can be made into the high-quality fertilizer.
Yet at present a large amount of draft oil cake of China is because shortage system, deep scientific research and high value-added product exploitation are developed particularly large-scale industrialization application so far as yet fully.Most draft oil cake goes out of use, and causes the great wasting of resources; Simultaneously, the draft oil cake that goes out of use is easily gone mouldy rotten, and contaminated soil and water body environment.These all suppress the quick of China's draft oil cake industry and develop in a healthy way.Therefore, carrying out the comprehensive utilization and the high value added product exploitation of draft oil cake, is draft oil plant industry urgent problem.
The draft oil cake is residual more grease, contains a certain amount of chemicals with higher fuel value simultaneously, is expected to make bioenergy.At present, China is greatly developing the plant renewable energy source, and the oil plant herbaceous plant is recent main support direction.At present, the conversion of the liquid fuel of biomass is one of its main mode with utilization.Therefore, the draft oil cake is prepared into liquid biological energy source, will improves value added applications scope, the minimizing wasting of resources and the environmental pollution of draft oil cake, the process of industrialization that promotes the draft oil cake is with healthy, fast-developing.
Summary of the invention
It is comparatively simple 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 draft oil slag liquid biological energy source of expensive device.
In order to solve the problems of the technologies described above, the preparation method of draft oil slag liquid biological energy source provided by the invention comprises the steps:
(1), the draft oil cake is dried, decon is made 10 orders～200 purpose oil cake powder;
(2), draft oil cake powder placed carries out the direct heat cracking under the oxygen free condition, the thermo-cracking temperature is 230 ℃～830 ℃, the cooling of thermal cracking gas room temperature, draft oil cake pyrolysis oil;
(3), under 15-110 ℃, 0-0.85MPa vacuum, with the pyrolysis oil of draft oil cake separate, evaporation, after the evaporant cooling, promptly get the draft oil slag liquid biological energy source, resistates is a solid state energy sources.
Draft oil cake described in the above-mentioned steps 1 is meant castor-oil plant oil cake, sesame oil cake, flax oil cake, Semen Helianthi oil cake or corn oil cake.
Oxygen free condition described in the above-mentioned steps 2 is carbonic acid gas, helium, nitrogen one of them or arbitrary proportion mixture.
Room temperature described in the above-mentioned steps 2 is 6 ℃～28 ℃.
Adopt the preparation method of the draft oil slag liquid biological energy source of technique scheme, under oxygen free condition, by thermal-cracking method the draft oil cake is transformed into liquid biological energy source, transformation efficiency is more than 46%.The liquid biological energy source of this draft oil cake is environmentally friendly, is with a wide range of applications at the renewable energy source domain of draft oilseed plant.Method operating procedure provided by the invention is comparatively simple, and controllability is better, and cost is lower, does not need expensive device, and easily realizes industrialization.
