Embodiment 1

[0039] Add 50g of algae fat, 450g of methanol, and 5g of ion-exchange resin into the transesterification device, apply ultrasonic stirring, heat to 50-65°C and react for 30-35 minutes, and measure the conversion rate to be over 96% to complete the reaction. Separating the mixed solution in a separating funnel, separating the glycerol layer, and then performing atmospheric distillation to recover excess methanol, and the remaining fatty acid methyl ester liquid fuel.

Embodiment 2

[0041] Take 20g of the above fat, 180g of methanol, and 5g of ion exchange resin, add them to the transesterification reaction device, control the reaction temperature at 40-50°C, and react for 30-40 minutes under ultrasonic stirring, and measure the conversion rate to reach more than 96%. The separator separates the lower layer of glycerin, and then distills excess methanol, and the rest is biodiesel.

Abstract

The invention relates to a production method of biodiesel, which comprises the following steps: using algae capable of generating fat in the algae comprising chlorella, haematococcus pluvialis and halophila, and using the algae as raw materials; performing algae culture first, and then extracting the fat from the algae; and performing ester exchange reaction, standing, demixing and redistillationon the fat to obtain the biodiesel. The production method has the advantages of simple process, short reaction time, high efficiency and no pollution to the biodiesel, can reduce the environmental pollution and the greenhouse effect, has wide resources of the raw materials, is suitable for mass production, and can produce huge economic benefits and social benefits.

Description

technical field [0001] The invention relates to a production method of alternative energy, more particularly to a production method of biodiesel. Background technique [0002] Energy shortage and environmental degradation have become major issues of worldwide concern, and they are also the primary issues that plague the sustainable economic and social development of countries all over the world. With the rapid increase of my country's automobiles, the large demand for energy in various industries, and the rise in world crude oil prices, my country's energy supply continues to be tight. It has been reported that 82% of CO, 48% of NOx, 58% of HC and 8% of particulate matter in the urban atmosphere come from automobile exhaust. In addition, cars emit a large amount of CO 2 exacerbated the greenhouse effect. Therefore, the development of new environmentally friendly renewable energy sources to replace conventional automotive fuels has been increasingly valued by various count...
