摘　　要：以邻苯二甲酸二异丁酯为原料,采用固定床高压反应器,对用于制备六氢化邻苯二甲酸二异丁酯的自制催化剂进行了性能研究,并与市售催化剂进行对比。试验结果表明:自制催化剂具有良好的低温加氢活性及大空速加工能力。在反应压力为4.5 MPa、温度为80~140℃、空速为0.37 h^(-1)、氢油体积比为500∶1条件下,工业装置稳定运行超过10000 h,加氢性能稳定,产品中DIBE的质量分数高于市售催化剂0.56个百分点,催化剂使用寿命是市售催化剂2倍以上。Using diisobutyl phthalate as raw material,performance of the self-prepared catalyst for the preparation of diisobutyl hexahydrophthalate was studied and compared with the commercial catalyst in a fixed-bed high-pressure reactor.The experimental results indicated that the self-prepared catalyst possessed good low-temperature hydrogenation activity and high space velocity reaction ability.Under the following parameters:reaction pressure was 4.5 MPa,reaction temperature was 80-140℃,the space velocity was 0.37 h^(-1) and volumetric ratio of hydrogen to oil was 500∶1,the industrial unit could operate stably for more than 10000 h,and the hydrogenation performance was stable.DIBE content in the product was 0.56 percentage points higher than that of the commercial catalyst.The service life of catalyst was more than 2 times of the market catalyst.
