Problems solved by technology

The fuel oil treated by the traditional acid-alkali refining method is difficult to meet the new low-sulfur standard, and the process itself has problems such as pollution and serious corrosion; because the biological desulfurization technology has not been well resolved in terms of desulfurization speed and stability , so biological desulfurization has not yet shown its obvious advantages; catalytic oxidation desulfurization technology is very popular in small and medium-sized refineries because of its mild operating conditions and low production costs

Embodiment 1

[0023] Hawthorn is a commonly used Chinese medicinal material, also known as Shanliguo and Shanlihong, a small deciduous tree in the Rosaceae family. Its fruit contains chemical components such as flavonoids, flavans, triterpenoids and organic acids, among which hyperin and ursolic acid are The main components of flavonoids and triterpenoids are the active components of hawthorn for lipid-lowering. Hawthorn contains a large amount of fruit acid, maslinic acid, citric acid, lipase and lipase, which can promote fat decomposition and degrade cholesterol and triglyceride. In addition, it also contains organic amine chemical components such as choline and acetylcholine, which are also effective components for lowering fat.

Abstract

The invention discloses a method of applying insulin to coking diesel oil desulfurization. The method comprises the following steps: (1) adding medicinal dried hawthorn powder or hawthorn water into coking diesel oil, heating and stirring in a magnetic stirring machine, conducting reaction for 60-100 min, taking out the coking diesel oil, and cooling to the room temperature; (2) adding insulin into the coking diesel oil obtained in the step (1) according to the mass-to-volume ratio of (0.05-1):1, then placing in a thermostatic water bath environment, heating at constant temperature while stirring for 1-24 h; (3) adding a catalyst and an oxidant into the coking diesel oil in sequence, and conducting catalytic oxidation reaction in the magnetic stirring machine for 50-100 min; (4) cooling to the room temperature, adding an extracting agent according to the volume ratio of 1:1, stirring in the magnetic stirring machine for 5-10 min, then pouring the mixture into a separating funnel, leaving the mixture to stand for 20 min, and collecting the diesel oil layer. According to the method, the reaction conditions of desulfurization and refining are mild, environment can be protected, the desulfurization rate is high, the yield of the coking diesel oil is obvious, and the color and smell of the coking diesel oil are light.

Description

technical field [0001] The invention relates to desulfurization technology of coked diesel oil, in particular to a method for desulfurizing coked diesel oil with high desulfurization rate. Background technique [0002] With the enhancement of people's awareness of environmental protection, people have increasingly strict requirements on the sulfur content of fuel oil. All countries in the world have formulated stricter new regulations on the sulfur content in fuel oil. In 2006, the United States stipulated that the sulfur content of diesel oil should be reduced from 500 μg / g to 15 μg / g; while Europe has implemented the Euro V standard with a sulfur content of 10 μg / g in 2009; Japan is an advanced country that produces clean gasoline, and the JISK 2202 gasoline standard implemented According to regulations, in 2005, the sulfur content of gasoline in Japan was limited to 50ppm, and in 2009, the ultra-low sulfur gasoline standard with a sulfur content of 10ppm was uniformly imp...
