Abstract

Abstract:

Sulfur was removed from diesel oil by using the ultrasonic oxidation process to reduce the sulfur content in diesel fuel. The effect of different oxidation temperature, oxidation time, oxidant dosage and catalyst dosage on diesel desulfurization were studied by experiments. Experimental results showed that using the formic acid mixture with sulfuric acid as catalyst, catalyst amount 2% (the volume ratio of formic acid and sulfuric acid in the catalyst was 3∶2), oxidant amount 9%, reaction temperature 70 ℃, reaction time 60 min, removing the sulfur in heavy oil catalytic cracking diesel oil by using ultrasonic oxidation, then through DMF extraction and oxidation, the diesel oil desulfurization rate could reach 83%， And cetane value was increasing, thus the quality of diesel oil was refined.

摘要： 采用超声氧化法脱除柴油中硫化物,降低了柴油的硫含量。实验考察了氧化温度、氧化时间、氧化剂体积分数、催化剂体积分数等条件对柴油脱硫效果的影响。结果表明,选用甲酸与硫酸混合物作为催化剂,催化剂体积分数为2%(催化剂中甲酸与硫酸体积比为3∶2)、氧化剂体积分数为9%、反应温度为70 ℃、反应时间为60min时,采用超声氧化法脱除重油催化裂化柴油中的硫化物,再经N,N-二甲基甲酰胺(DMF)萃取氧化,柴油脱硫率达到83%,十六烷值有所升高,提高了柴油的质量。
