摘要
设计了一套实验室加氢反应生成山梨醇的装置,用来测试含钌加氢催化剂的活性,比较了反应过程中温度、压力和搅拌速度对催化剂活性的影响。结果表明,测定含钌加氢催化剂的最佳条件为:温度在120℃￣140℃之间,压力在3MPa￣4MPa之间,搅拌速度在200r/min￣400r/min之间。用氧化还原滴定法测定含钌加氢催化剂的活性是可行的,与国外原有的测试方法相比,测试温度和压力要低得多,且测试时间缩短。
A set of laboratory-seal device in which the sorbierite is formed by hydrogenation is desighned for measuring the activity of ruthenium-hydrogenation catalyzer, and the effects of temperature,pressure and stir speed on the activity of catalyzer are also analyzed.The results show that the appropriate testing condition is as follows： temperature is 120℃～140℃, pressure is 3 MPa～4 MPa, and milling speed is 200 r/min～400 r/min.It is feasible to mensurate the activity of hydrogenation catalyzer by oxidation-reduction titration. As compared with overseas mensuration, the temperature and pressure for mensurating are much lower and the mensurating duration is short.
