摘要

中文摘要: 采用WO3/ZrO2固体超强酸作为催化剂，研究了H2O2/WO3/ZrO2体系催化氧化柴油深度脱硫性能，考察了氧化剂用量、催化剂用量、反应温度、反应时间等工艺参数对脱硫率的影响；在此基础上，引入功率超声进一步强化反应，并考察了超声频率、超声功率、超声时间等因素对脱硫效果的影响。实验结果表明，在反应温度60 ℃，反应时间90 min，氧化剂加入量V(H2O2)∶V(柴油)= 1∶10，催化剂用量15 g/L柴油的最佳氧化脱硫条件下，氧化柴油经萃取后脱硫率可达91.0%。超声强化后，氧化反应时间缩短为40 min，柴油脱硫率提高至95.6%。

Abstract

Abstract:Using WO3/ZrO2 solid superacid as catalyst

the performance of H2O2/WO3/ZrO2 system on the catalytic oxidative deep desulfurization of diesel were studied. The technical parameters

such as the amount of oxidant

the dosage of catalyst

the reaction temperature and the reaction time were investigated.Furthermore

the power ultrasound was introduced to enhance the process.The effects of ultrasonic frequency

intensity and time on the desulfurization were investigated.The experiment results revealed that under the optimum oxidative desulfurization conditions of oxidation temperature 60 ℃，reaction time 90 min，the oxidant dosage V(H2O2)∶V(diesel)= 1∶10 and the catalyst dosage 15 g/L diesel，after extraction of oxidized diesel the removal efficiency of sulfur compounds was up to 91.0%.The oxidation time with ultrasound were shortened to 40 min and the removal efficiency of sulfur compounds was increased to 95.6%.
