采用正交实验法对轻柴油的无碱脱硫醇工艺进行了研究 ,初步探索出脱硫醇反应的较佳工艺条件为 :活性炭固载催化剂的用量 0 .8mg/L ,反应温度 4 0℃ ,空速 2h-1,活化剂 (季胺盐类 )用量 (对油 ) =10 0 μg/g。硫醇脱除率可达 90 % ,通过反应动力学研究得知轻柴油脱硫醇反应级数为 1.2 5级 ;反应速率常数为 7.4 2×10 -2 (mol/m3 ) -0 .2 5/h ;反应活化能 180 .6kJ/mol。

STUDY ON MERCAPTAN REMOVAL FROM LIGHT DIESEL OIL WITHOUT CAUSTIC-SODA

The reaction of mercatan removal from light diesel oil without caustic soda was studied. The preliminary optimum conditions were obtained as follows:the amount of catalyst supported activate carbon(to oil)=0.8 mg/L, reaction temperature 40 ℃,space velocity 2 h -1 , activator(to oil)=100 μg/g. The removal of mercaptan is up tp 90%. The reaction kinetics were studied also, and the results were: reaction order 1.25, reaction rate constant 7.42×10 -2 (mol/m 3 ) -0.25 /h; activation energy 180.6 kJ/mol.
