Embodiment 1
[0018] The acidified rapeseed oil of 1000 kilograms of edible oil production plants is heated to 70 ℃ and then adds the aluminum sulfate of 1% by weight of raw material oil ester weight and is 30% aluminum sulfate, stirs 30 minutes, static precipitation 24 hours, collects supernatant liquid, and deposit can For biological fertilizer, the supernatant is filtered to remove impurities to obtain relatively pure raw materials.
[0019] Put the above-mentioned 1000 kilograms of pretreated raw oil esters, 150 kilograms of methanol and 10 kilograms of sodium formate into the heating kettle, stir and react, the stirring speed is 30 revolutions / min, the reaction temperature is 65 ° C, reflux for 1 hour, and then Stand still for 1 hour to separate layers, discharge acid water, reclaim methanol, wash with water, and obtain crude methyl ester with a weight of 95%;
[0020] Then add 1 kg of boric acid, stir evenly, pump into the distillation kettle to heat up to 220°C, and the vacuum degree...
Embodiment 2
[0024] Put 800 kg of roast duck oil, 120 kg of methanol and 4 kg of sodium formate into the esterification kettle, heat it to 70°C under normal pressure, reflux for 2 hours, and recover excess methanol by steaming. After the reaction, stand still for 1.5 After 1 hour, discharge the acidic water, then wash with water to obtain 760kg of crude methyl ester, then add 0.8kg of boric acid, stir evenly, pump it into the distillation kettle and heat it to 220 ° C ~ 280 ° C, and distill it under the condition of a vacuum of 0.09 MPa to obtain 684 kg of biodiesel.
[0025] Refer to GB / T17411~1998, ISO 8217:1996 standard for detection and testing, the test results are as follows:

Abstract
The invention discloses a bio-diesel and the preparation method, which comprises the following steps, first, raw materials like oil, methyl alcohol and sodium formate are stirred together for reaction, a reaction product of crude methyl ester is gathered, the oil comprises one or more of acidic oil in an edible oil producing factory, foot oil, hogwash oil in an animal butchery, restaurants and food manufacturers and sewerage oil, second, boric acid is added into the gathered crude methyl ester for vacuum distillation to get target products, bio-diesel. The bio-diesel produced through the method is the fuel prepared by waste materials, which can be in combined use with OWM tripropellant and further improve the quality of OWM tripropellant and reduce the exhaust amount of harmful gas, the products can also be put into light diesel oil, which can reach the same effect or be used separately, and the products can completely replace light diesel oil and be much better than light diesel oil, which is real green diesel oil, the method provided by the invention is characterized by no exhaust of waste water, waste gas and waste liquor, no environmental pollution and filter materials being regarded as biofertilizer.
Description
technical field [0001] The present invention relates to a biodiesel and its preparation method, in particular to a biodiesel prepared from acidified oil from edible oil production plants, oil feet, animal slaughter plants, restaurants, food processing plants, swill oil, sewer oil, etc. diesel fuel. Background technique [0002] Acidified oil, oil feet from edible oil production plants, animal slaughterhouses, restaurants, food processing plants, swill oil, sewer oil, etc. are waste materials that seriously pollute the environment and must be treated before they can be discharged. [0003] Whether the above-mentioned waste materials can be processed and recycled in a suitable way is a matter of great concern to people. Contents of the invention [0004] The technical problem to be solved in the present invention is to disclose a kind of biodiesel and its preparation method, which is to recycle the acidified oil, oil foot from edible oil production plant, swill oil and sewe...
