Embodiment 1

[0039] Weigh 100 g of cottonseed oil into a three-necked flask equipped with a stirring device, a condensation reflux device and a thermometer, and place it in a constant temperature water bath device with a preset temperature of about 65°C. Take about 1% NaOH of oil weight, dissolve in anhydrous methanol, the molar ratio of anhydrous methanol and cottonseed oil is 6:1. Mix anhydrous methanol in which NaOH is dissolved with coconut oil, and stir for about 2 hours at a rotation speed of about 600r / min. After the reaction is completed, transfer it to a separatory funnel to stand still for more than 8 hours, and the upper layer is the crude biodiesel product. Take the crude biodiesel in the upper layer, and evaporate excess methanol at 80°C. Wash the evaporated biodiesel several times with distilled water until the washing water is clear and transparent. Finally with anhydrous NaSO 4 The excess water is removed, and the biodiesel product is obtained after filtration.

Embodiment 2

[0042] Get 30 parts by volume of coconut oil biodiesel, 15 parts by volume of rapeseed oil biodiesel, 20 parts by volume of cottonseed oil biodiesel, 15 parts by volume of tung oil biodiesel and 20 parts by volume of waste oil biodiesel Mix well in tube 1. This blended biodiesel is denoted B100. Take the mixed biodiesel in test tube 1 and mix them with mineral diesel respectively at mixing ratios of 30%, 20%, 10%, and 0% to form a blended oil. The blended oils are correspondingly expressed as B30, B20, B10, B0.

[0043] Follow GB380-77 to measure the sulfur content of blend oil B100, B30, B20, B10 and B0 respectively; follow GBT5538-2005 to measure the peroxide value of blend oil B100, B30, B20, B10 and B0 respectively; follow SH / T0248 to measure the blend Cold filter point for oils B100, B30, B20, B10 and B0. The measurement results of sulfur content, peroxide value and cold filtration point are shown in Table 1-3.

Embodiment 3

[0045] 20 parts by volume of coconut oil biodiesel, 30 parts by volume of cottonseed oil biodiesel, 20 parts by volume of tung oil biodiesel and 30 parts by volume of waste oil biodiesel of Example 1 were placed in test tube 2 and fully mixed. This blended biodiesel is denoted B100. Take the mixed biodiesel in test tube 2 and mix them with mineral diesel respectively at mixing ratios of 30%, 20%, 10%, and 0% to form a blended oil. The blended oils are correspondingly expressed as B30, B20, B10, B0.

[0046] Follow GB380-77 to measure the sulfur content of blend oil B100, B30, B20, B10 and B0 respectively; follow GBT5538-2005 to measure the peroxide value of blend oil B100, B30, B20, B10 and B0 respectively; follow SH / T0248 to measure the blend Cold filter point for oils B100, B30, B20, B10 and B0.

[0047] The measurement results of sulfur content, peroxide value and cold filtration point are shown in Table 1-3.

Abstract

The invention discloses blended biodiesel, which mainly comprises cotton oil biodiesel, tung oil biodiesel and sinking fat biodiesel, wherein, the volume ratio of the cotton oil biodiesel to the tung oil biodiesel to the sinking fat biodiesel is equal to 15-35 to 10-60 to 15-35. The blended biodiesel has low cost and simple and easy operation process, is environment-friendly, integrates the advantages of various raw material biodiesel and petrochemical biodiesel, and can improve the performance of the biodiesel better.

Description

technical field [0001] The invention belongs to the technical field of green and renewable energy, and in particular relates to an optimized biodiesel blended from various biodiesels. Background technique [0002] As a kind of green energy, biodiesel has the advantages of good combustion properties, renewability, and environmental friendliness, and has become the most promising petroleum substitute. Today, with the depletion of oil resources and the improvement of people's awareness of environmental protection, more and more attention has been paid to biodiesel, and the development of biodiesel has become the focus of research in various countries. At present, countries including the United States, the European Union, Japan and China are vigorously developing biodiesel. However, compared with the development of relatively mature petrochemical diesel, there are inevitably some problems in the commercialization of biodiesel, mainly manifested in high raw material cost, high v...
