| 摘 要： | 研究了苯甲酸加氢过程中Pd/C催化剂的失活原因，针对CO引起Pd/C活性降低，开发了SRNA－5助催化剂，有效消除了反应中生成的CO对Pd/C催化剂活性的影响。并在石家庄化纤公司完成了工业试验，工业试验表明，在不改变原工业流程的基础上，通过向苯甲酸加氢工业装置中加入SRNA－5助剂，有效提高Pd/C催化剂活性，该厂每年减少催化剂直接费用1500万元。

| Abstract: | Utilizing an improved method for adding promoter to the precious Pd/C in the hydrogenation of benzoic acid,new understanding has been obtained concerning the deactivation Pd/C catalyst,and an improved process has been achieved.A promoter SRNA-5 is deucloped to eliminate effectiacly the CO formed from the reaction,which is the main reason in reducing the activity of Pd/C catalyst.A reduction of cost in buying the catalyst is expected to be around RMB 15 million annually. |
