摘要/Abstract

摘要： 以邻苯二甲酸二异丁酯（DIBP，工业级）为原料，采用固定床高压反应器，对DIBP脱硫-加氢制备环己烷-1，2-二甲酸二异丁酯反应的催化剂和工艺进行了研究，增加了DIBP原料中痕量硫的脱除工艺，考察了反应压力、温度、空速、氢油比等工艺参数对DIBP脱硫及加氢反应的影响。试验结果表明：在反应压力14MPa、温度110℃（脱硫段）、温度160℃（加氢段）、空速0.3h^-1、氢油比600：1的最佳条件下，装置稳定运行1000h，DIBP中的硫含量为3.5μg/g，DIBP转化率99.94%，脱硫和加氢性能稳定。

Abstract: Desulfurization-hydrogenation of di-isobutyl phthalate was studied on a fixed-bed reactor,using di-isobutyl phthalate(DEHP,industrial grade)as raw material. The influences of pressure,temperature,liquid hourly space velocity and volumetric ratio of hydrogen to oil on the activity of desulfurizer and catalyst were investigated.The experimental results indicated that the optimal operating parameters were:pressure 14MPa,reaction temperature 110℃(desulfurization part),160℃ (hydrogenation part),liquid hourlyspace velocity 0.3h^-1 and volumetric ratio of hydrogen to oil 600:1,under which,the desulfurizer and catalyst exhibited excellent and stable activity during the 1000h running test,the sulfur content of DIBP was 3.5ppm and the conversion kept above 99.94%.

Key words: di-isobutyl phthalate, di-isobutyl-1,2-cyclohexanedicarboxylate, desulfurization, hydrogenation, environment-friendly plasticizer
