Abstract
The invention discloses a manufacturing method for green environment-friendly biodiesel, which comprises the following steps: by taking animal and plant oil, recycled cooking oil, and animal oil leftovers of leather factories and slaughterhouses as raw materials, carrying out impurity removal, purification and dehydration, adding into a reaction kettle and heating to 40DEG C-55DEG C; according to the weight of active ingredient oil, adding 2% of composite catalyst, 3% of cosolvent and 10%-20% of methanol, and carrying out fast esterification reaction and replacement to obtain fatty acid methyl ester; preserving heat, agitating for 30-60 minutes, standing for three hours for layering, taking upper-layer liquid and adding 5% lightweight oil, thus obtaining the biodiesel. The manufacturing method has no emission of three wastes in the production process, is low in reaction temperature, fast in reaction speed, energy-saving and high-efficiency, and simple in production technique, and the problems that an existing biodiesel production method is low in output, long in period, high in energy consumption, and easily causes environmental pollution are well solved.
Description
Technical field
The invention belongs to biodiesel technology field, relate in particular to a kind of manufacture method of green environment protective biological diesel oil.
Background technology
Biofuel abroad receives much concern again, and is widely used.In the country such as European, German, French, Italian, biofuel is taked to support policy.Germany takes fiscal subsidy to peasant planting biofuel crop, and Fa Guodui production of biodiesel factory not only fiscal subsidy also exempts from the various expenses of taxation.The U.S. promotes the development of biofuel to take strong subsidies measures, therefore, and the national Jun Shi world main producing countries of biofuel such as U.S., moral, method.Biofuel, as the clean renewable energy resources of high-quality, also receives much concern at home.Utilize sewer oil, edible oil leftover bits and pieces acidification oil, tannery, butcher leftover bits and pieces animal grease etc. for raw material production biofuel, can reduce atmospheric pollution, alleviate the discharge of PM2.5, development diversification energy system, also can reduce the dependence to petroleum.The at present domestic and international universal method three major types of the production of biofuel: esterification, transesterify, High Temperature High Pressure cracking.Esterification class yields poorly, and esterification time is long, has three waste discharge.High Temperature High Pressure cracking class, high to equipment requirements, invest large big energy-consuming, there is three waste discharge.Transesterify class, energy consumption is high, has three waste discharge.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of manufacture method of clean biofuel, is intended to solve yielding poorly that the production method of existing biofuel exists, and the cycle is long, and energy consumption is high, easily causes the problem of environmental pollution.
The embodiment of the present invention is achieved in that a kind of manufacture method of green environment protective biological diesel oil, and the manufacture method of this green environment protective biological diesel oil comprises the following steps:
Step 1, animal-plant oil, sewer oil, tannery slaughterhouse leftover bits and pieces animal grease are raw material, through removal of impurities, purification, dehydration, add and in reactor, are heated to 40 degree～55 degree;
Step 2, adds 2% composite catalyst of stock oil weight, and composite catalyst is sodium sulfate and sodium hydroxide, 3% cosolvent, and cosolvent is dme, carries out esterification fast and is replaced into fatty acid methyl ester;
Step 3, insulation, stirs 30 minutes～60 minutes, and standing 3 little layereds are got supernatant liquid and are added 5% light oil and close, and obtain biofuel.
Further, in step 2, the add-on of methyl alcohol the best is 15% of stock oil weight.
Further, in step 3, light oil can be condensate oil, petroleum naphtha, lightweight oil.
Further, the manufacture method of this green environment protective biological diesel oil is: adopt sewer oil, edible oil leftover bits and pieces acidification oil, tannery, slaughterhouse's leftover bits and pieces vegetable and animals oils or animal-plant oil, one or several all can, carry out in advance, after removal of impurities, purification, dehydration, getting stock oil 1000g, methyl alcohol 150g, under the stirring velocity of 300 revs/min, insulated and stirred 40 minutes, standing 3 little layereds, upper strata adds 50g light oil and is biodiesel for automobile.
The manufacture method of green environment protective biological diesel oil provided by the invention, adopts discarded animal and plant grease, sewer oil, edible oil leftover bits and pieces acidification oil, tannery, slaughterhouse's leftover bits and pieces animal grease, all can do raw materials for production.Raw material is first through removal of impurities, purification, processed.Then add reactor, be heated to 40 degree～55 degree, add composite catalyst, cosolvent, low-carbon alcohol, keep temperature with the stirring velocity reaction of 300 revs/min 30 minutes-60 minutes, stratification, gets supernatant liquid and refuels heavy 5% light oil blending.Obtain startability, dynamic property is good, waste gas, the low biofuel of PM2.5 discharge level.Production process three-waste free discharge of the present invention, temperature of reaction is low, and speed of response is fast, efficient energy-saving, the simple biofuel making method of production technique, preferably resolves yielding poorly that the production method of existing biofuel exists, cycle is long, and energy consumption is high, easily causes the problem of environmental pollution.
