preparation example Construction

[0021] A kind of preparation method of diesel oil deacidification agent, this preparation method comprises the steps:

[0022] (1) According to the mass ratio of 1:1:1:1, mix tangerine peel, shelled tea seeds, wheat straw, and rice straw, and grind them to 0.1~5mm to obtain crushed products. According to the mass ratio of 1:7~8, Mix the pulverized matter and ethanol, ultrasonically extract and degrease at a temperature of 40~60°C, filter to obtain a degreased matter, perform rotary evaporation on the degreased matter, add water 3~4 times the amount of the degreased matter, and degrease at a temperature of 30~50°C Naturally ferment for 150-180 hours, filter to obtain filter residue, and set aside;

[0023] (2) Wash the peanut shells and pass through a 30-40 mesh sieve to obtain the sieved product. According to the mass ratio of 1:20, mix the sieved product and a sulfuric acid solution with a mass fraction of 10-15%, and heat it at a temperature of 100-120 Stir for 40-60 minute...

Abstract

The invention relates to the field of petroleum processing, in particular to a preparation method of a diesel deacidification agent. The method also utilizes chitosan as a carrier, and adopts carbodiimide to activate and immobilize lipase; free fatty acid can be directly esterified by means of the lipase, and the introduction of the carbodiimide actually plays a chemical modification effect on enzyme molecules; carbonic acid is converted into amine, so that the affinity is enhanced; furthermore, the electric field on the surface can be changed, so that the activity of the lipase is improved. Therefore, the diesel deacidification agent is prepared by using natural and non-toxic matters as raw materials, thus not corroding equipment and causing environmental pollution.

Description

technical field [0001] The invention relates to the field of petroleum processing, in particular to a preparation method of a diesel deacidification agent. Background technique [0002] At present, with the depletion of crude oil resources in the world and the continuous innovation of mining technology, the output of high-acid crude oil is increasing at a rate of 0.3% per year. During the processing of high-acid crude oil, the acidic substances (mainly naphthenic acid) in it seriously affect its normal processing and oil performance. For this reason, the naphthenic acid in the oil must be removed to meet the industrial requirements. [0003] The acidic substances contained in crude oil are collectively referred to as petroleum acids, including inorganic acids, naphthenic acids, other organic acids, phenols and mercaptans. Among them, the content of naphthenic acid accounts for about 90% of the total acidic substances, and the acidity of oil products is mainly caused by nap...
