Embodiment 1

[0018] 1. Esterification: Get 3000Kg of brownish black corn oil with acidity AV=152, add concentration as 450Kg of 98% industrial methanol and 27Kg of 98% industrial sulfuric acid, pump the above-mentioned waste oil, methyl alcohol and sulfuric acid into 5000 In the rising esterification tank, open the reflux cooling water and hot oil heating valve to heat up. After about 1 hour, methanol reflux appears in the methanol reflux cup, and the gas phase temperature is 70°C; the gas phase temperature is 70-73°C Under the condition of temperature, methanol was refluxed for 5 hours; under the condition of gas phase temperature of 73-85°C, methanol was refluxed for 3 hours and 15 minutes; AV≤15, the cumulative reflux time is 11 hours and 15 minutes, the reflux time is more than 10 hours, and the reflux time is preferably 10-12 hours to obtain qualified crude ester.

[0019] Close the reflux valve, open the methanol distillation valve, distill the remaining methanol, and collect the dis...

Abstract

A process for preparing biologic diesel oil from waste plant or animal oil includes alcoholysis and esterifying reactions under the existance of acidic catalyst, separating out the excessive non-product part to obtain coarse product, adding saturated equeous solution of edible salt containing sodium carbonate (10%), neutralizing reaction, adding industrial sodium carbonat4e, heating distillation and collecting the gas-phase fraction at 22-320 deg.C to obtain biologic diesel oil. Its advantages are high performance no pollution, and simple preparing process.

Description

(1) Technical field: [0001] The invention relates to a process for producing biodiesel from waste animal and vegetable oil. (two) background technology: [0002] Experts predict that oil resources will be exhausted in the 21st century. All countries in the world are using oil resources more economically and effectively, and are actively developing new energy sources or developing alternative fuels. In recent years, many countries in Europe have developed a fuel oil similar to diesel produced by methyl esterification of vegetable oil with methanol. This oil is called "biodiesel" abroad. Because the oil can completely replace diesel oil, and because the exhaust gas after combustion does not contain sulfur dioxide and produces less nitrogen oxides, it greatly reduces the environmental pollution caused by burning fuel oil. This biodiesel is a new type of green and environmentally friendly fuel. Take the United States as an example. In 1999, the sales volume of biodiesel was onl...
