Embodiment 1-12

[0036] Embodiment 1-12: The component contents in the following embodiments are all by weight.

Embodiment 1

[0038] The improver includes the following components: TBHQ, JN-2000 pour point depressant (produced by Tianjin Perfect Petroleum Technology Co., Ltd.). The preparation method is as follows: Weigh 6g of TBHQ by weight, add 100g of better quality RME, heat to 40°C while stirring to completely dissolve TBHQ, then add 10g of JN-2000 pour point depressant, stir and mix to prepare the improver. The content of TBHQ in the improver is 5.17%, and the content of JN-2000 pour point depressant is 8.62%. The addition and application process is as follows: Weigh 0.58g of improver, add 50g of RME, stir and mix well, so that the content of TBHQ in the RME sample is 0.06%, and the content of JN-2000 pour point depressant is 0.1%. Table 1.

Embodiment 2

[0040] The improver includes the following components: TBHQ, VE, T818 pour point depressant (produced by Shanghai Renyinglian Economic and Trade Development Co., Ltd.). The preparation method is as follows: Weigh 2g TBHQ and 2g VE by weight, add 100g of better quality RME, heat to 40°C while stirring to completely dissolve TBHQ and VE, then add 10g of T818 pour point depressant, stir and mix well to prepare an improved agent. The content of TBHQ and VE in the improver is 1.75%, and the content of T818 pour point depressant is 8.77%. The process of adding and applying is as follows: weigh 0.57g of improver, add 50g of RME, stir and mix well, so that the content of TBHQ and VE in the RME sample is 0.02%, and the content of T818 pour point depressant is 0.1%, and the test results of IP value and CFPP value of the sample See Table 1.

Abstract

The present invention relates to one kind of biodiesel oil modifier and its preparation process. The biodiesel oil modifier is compounded with antioxidant 1-10 weight portions, antioxidant synergist 0-5 weight portions, biodiesel oil of rape seed oil 50-100 weight portions, and low temperature flow improver 5-50 weight portions. The biodiesel oil modifier can raise the stability of biodiesel oil and improve its low temperature flow performance effectively, and has convenient use, wide adaptability, long storage period, capacity of being used in low temperature and low cost.

Description

technical field [0001] The invention relates to a biodiesel improver for improving biodiesel oxidation stability and low-temperature fluidity and a preparation method thereof. The improver can effectively prolong the oxidation induction period (IP value, 110°C, h) of biodiesel, obviously Its cold filter point (CFPP, ℃) is lowered, and it belongs to the application field of oil chemistry and chemical industry. Background technique [0002] Biodiesel is a mixture of fatty acid alkyl esters obtained by transesterifying animal oil, vegetable oil, waste cooking oil, etc., with low-carbon alcohols under certain conditions, usually a mixture of fatty acid methyl esters. Biodiesel is environmentally friendly, biodegradable and renewable, and is a good substitute and important supplement for petrochemical diesel. However, compared with petrochemical diesel, the oxidation stability of biodiesel is poor, which limits the content of unsaturated fatty acid esters, especially highly unsa...
