Embodiment 1

[0017] Add 20g of soybean oil and 5g of sodium oxide into a four-necked flask equipped with a mechanical stirrer, a condenser, and a thermometer. When the temperature was raised to 420°C, a condensed liquid appeared. Afterwards, the remaining 80 g of soybean oil was added dropwise, and the dripping was completed within 2 hours. Continue to maintain catalytic cracking at 420°C until no fraction is generated. Catalytic cracking to obtain liquid 71g, residual carbon 5g, non-condensable gas 24g.

Embodiment 2

[0019] Add 20g of rapeseed oil and 5g of sodium oxide into a four-necked flask equipped with a mechanical stirrer, a condenser, and a thermometer. When the temperature was raised to 420°C, a condensed liquid appeared. After that, the remaining 80 g of rapeseed oil was added dropwise, and the dripping was completed within 2 hours. Continue to maintain catalytic cracking at 420°C until no fraction is generated. Catalytic cracking to obtain liquid 73g, residual carbon 6g, non-condensable gas 21g.

Embodiment 3

[0021] Add 20g of gutter oil and 5g of sodium oxide into a four-necked flask equipped with mechanical stirring, a condenser, and a thermometer. When the temperature was raised to 420°C, a condensed liquid appeared. After that, the remaining 80 g of waste oil was added dropwise, and the dripping was completed within 2 hours. Continue to maintain catalytic cracking at 420°C until no fraction is generated. Catalytic cracking to obtain liquid 70g, residual carbon 8g, non-condensable gas 22g.

Abstract

The invention discloses a method for preparing liquid fuel oil by catalyzing and cracking triglyceride, which comprises: a first step, according to a proportion of the triglyceride to a catalyst by mass being 100:1-10, weighing the triglyceride and the catalyst, and adding 5 to 30 percent of the triglyceride and the catalyst into a reaction kettle simultaneously; and a second step, heating the reaction kettle to between 350 and 500 DEG C, dropwise adding the rest 70 to 95 percent of the triglyceride into the reaction kettle, and condensing the generated vapor to obtain dark brown liquid, wherein the acid value is 16.4 mg KOH / g, the density is 0.84 g / cm3, the water content is 0.31 percent, the thermal value is 43.0 kilojoules per gram, and the viscosity is 3.1 mm2 / s.

Description

technical field [0001] The invention belongs to the technical field of biomass energy conversion, and mainly relates to a new method for preparing liquid fuel oil by catalytic cracking of triglyceride. Background technique [0002] The primary energy sources dominated by petroleum and coal are increasingly depleted, while biomass energy uses renewable or recycled organic substances, including crops, trees and other plants and their residues, as raw materials to produce bio-based products, biofuels and Bioenergy production industry. Among them, the catalytic cracking of triglyceride is an effective method for preparing liquid fuel. However, the conventional fuel oil obtained by using alumina as a catalytic cracking catalyst is not suitable for use as a high-quality fuel oil in terms of properties and composition, mainly because the catalytic cracking product contains a large amount of higher fatty acids, and the acid value is relatively high, up to 100mgKOH / g , so that soli...
