Embodiment 1

[0031] Embodiment 1 utilizes mountain pepper to prepare biological vegetable oil

[0032] A kind of mountain pepper biomass diesel oil production process, its concrete steps are as follows:

[0033] (a) using petroleum ether as a solvent, under the action of an ultrasonic instrument, carry out ultrasonic extraction to the mountain pepper powder under normal temperature conditions, the ultrasonic frequency is 40kHz, the ultrasonic extraction time is 40min, and crude oil is obtained;

[0034] In this example, the mass ratio of peppercorn powder and petroleum ether is 1:8. In actual operation, the mass ratio of peppercorn powder and petroleum ether is controlled within the range of 1:6-10, and the purpose of the invention can be achieved. .

[0035] (b) Use a rotary evaporator to rotary steam the crude oil, add 250-300ml of crude oil each time, work at a temperature of 60-70°C and a rotation speed of 60rpm for 45-60min, and steam out the residual petroleum ether;

[0036] Then ...

Abstract

The invention discloses a lindera glauca biomass diesel manufacturing process, and relates to the technical field of biofuel. The process flow comprises the following steps: by using petroleum ether as solvent, performing ultrasonic extraction on lindera glauca powder; then performing rotary evaporation, condensation reflux, hydration degumming, alkali refining and deacidification, thermal dehydration and other operation; adding methanol and a catalyst, and reacting together; and washing with water to remove residual glycerol, thereby obtaining the biodiesel. According to the invention, the biodiesel is directly obtained by using lindera glauca fruit as a raw material. Tests of a national certification body show that key indicators cetane number, cold filter plugging point, pour point, flash point, sulfur content, carbon residue and ash content as well as other indicators meet the requirements of the Chinese Standard GB/T20828-2014. The product has the characteristics of safety, cleanness and renewability.

Description

technical field [0001] The invention relates to the technical field of biofuel (Biofuel), in particular to a production process of mountain pepper (Lindera glauca) biomass diesel. Background technique [0002] With the continuous acceleration of human social and economic development and industrial modernization, the demand for energy represented by oil has increased sharply, while the global oil reserves are limited, and natural resources are gradually decreasing. The deterioration of the environment and climate has made energy and environmental issues increasingly prominent. [0003] In order to alleviate the pressure of relatively serious air pollution, combined with the development trend of vehicle diesel standards in Europe, America and Japan, my country is currently implementing the GB19147-2013 "Vehicle Diesel oil (Ⅴ)" standard. The standard meets the requirement that the mass fraction of sulfur in diesel oil be below 10 μg / g. The transition period is until December 3...
