[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...
