摘　　要：研究了碱性条件下温度、反应时间、模拟燃料油和氧化剂的比例对模拟燃料中苯并噻吩的去除效果的影响。结果表明,最佳脱硫反应条件为:反应温度为50℃,燃料与氧化剂的比为1∶1,反应时间为40 min。碱性条件下模拟燃油脱硫中苯并噻吩的去除率达到77.7%。与中性条件下的脱硫反应相比,模拟燃料油中苯并噻吩的脱硫率提高了48.8个百分点。铂碳本身具有一定的吸附脱硫能力,经过3次再生脱硫反应,铂碳的脱硫性能略有下降。The effect of temperature,reaction time,and the ratio of simulated fuel oil and oxidates on the removal effect of benzothiophene in simulated fuel under alkaline condition were investigated.The result showed that the optimal desulfurization reaction conditions is as follows:reaction temperature is 50℃,the ratio of fuel and oxidate is 1∶1,the reaction time is 40 min.The removal effect of benzothiophene in simulated fuel oil desulfurization under alkaline condition is acceptable and the removal rate reaches 77.7%.Compared to the desulfurization reaction under neutral condition,the desulfurization rate of benzothiophene in simulated fuel oil increased 48.8 percentage point;platinum carbon itself has a certain adsorption desulfurization capacity;the desulfurization performance of platinum carbon slightly decreased after three times of regenerated desulfurization reaction.
