Description
Technical field
The present invention relates to a kind of method that under oxygen free condition, prepares the oil tea oil slag liquid biological energy source.
Background technology
Oil tea is a Theaceae Camellia plant, is the main edible woody oil tree species of China, at province establishing in large scale such as China south.The oil tea oil cake claims that again tea is withered, the another name tea dregs of rice, tea bran, oil tea cake, tea seed cake, tea oil residule etc.Being the puce particle, is that the oil tea seed prepares the slag that is left behind the tea oil by methods such as squeezing or extractions, contains a large amount of polysaccharide, protein and tea saponin.Tea saponin is a kind of good tensio-active agent and whipping agent, and stronger soil removability is arranged, and can be used for producing pore forming material in paste shampoo, washing composition, foodstuff additive, scavenging agent and the flash arrestor etc.Because the protein content of oil tea oil cake is higher, can be made into plant protein fodder; The nitrogen of oil tea oil cake, phosphorus, potassium content are higher, therefore still a kind of efficient organic fertilizer.
Yet China at present can only the thick tea saponin of suitability for industrialized production, and saponin content is low, and therefore the foreign matter content height uses to be restricted, and most enterprise does not reach customer requirements and stops production because of production cost height, quality product.There is about 500,000 tons of the remaining oil tea oil cake in oil expression back in the whole nation every year, but is developed fully as yet so far, and part oil tea oil cake is taken as fuel and burns, or cheap outlet causes the significant wastage of resource.Even more serious is that the oil tea oil cake that overstocks is easily mouldy infested, and serious environment pollution, has restricted the sound development of camellia oleiferaindustry.
Comprehensive and the high value added utilization of oil tea oil cake, is carried out in China southern hills mountain area in the oil tea major production areas therefore, is an important channel of develop economy of mountainous terrain, also is simultaneously the effective means that solves three wastes problem, has very positive meaning.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.Therefore, the oil tea oil cake is prepared into the value added applications scope that liquid biological energy source will further improve the oil tea oil cake, can effectively reduces the wasting of resources and environmental pollution simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of operating procedure is simple, and cost is lower, and controllability is better, does not need the preparation method of the oil tea oil slag liquid biological energy source of expensive equipment and instrument.
The liquid biological energy source of oil tea oil cake of the present invention is characterized in that: under oxygen free condition the oil tea oil cake is transformed into liquid biological energy source, transformation efficiency is more than 57%.
In order to solve the problems of the technologies described above, the preparation method of oil tea oil slag liquid biological energy source provided by the invention comprises the steps:
(1), the oil tea oil cake is made 20 orders～80 purpose powder;
(2), under the oxygen free condition, oil tea oil cake powder is carried out the direct heat cracking, the thermo-cracking temperature is 180 ℃～890 ℃, and thermal cracking gas is carried out the room temperature cooling, promptly gets pyrolysis oil;
(3), under 4-115 ℃, 0-0.96MPa vacuum, with oil tea oil cake pyrolysis oil separate, evaporation, after the evaporant cooling, promptly get the oil tea oil slag liquid biological energy source, resistates is a solid state energy sources.
Oil tea described in the above-mentioned steps 1 is meant all kinds of Camellia oil tea group.
Oil tea oil cake described in the above-mentioned steps 1 also claims that tea is withered, the tea dregs of rice, tea bran, oil tea cake, tea seed cake, tea oil residule.
Oil tea oil cake 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 tea oil from the oil tea seed.
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 oil tea oil slag liquid biological energy source of technique scheme, under oxygen free condition the oil tea oil cake is transformed into liquid biological energy source, transformation efficiency is more than 57%.The liquid biological energy source of this oil tea oil cake 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, and cost is lower, and controllability is better, does not need expensive equipment and instrument, and is easy to industrialization.
