摘　　要：自制了六通道固定床反应器,以蒽醌加氢为测试反应研究了该反应器的实用性。测试结果表明,该反应器各平行反应通道的相对误差小于3%。利用该反应器进行了蒽醌加氢Pd/Al2O3催化剂研究,考察了浸渍浓度、焙烧温度对催化剂加氢性能的影响,得到Pd粒子最佳浸渍浓度为1.2g/L,适宜焙烧温度为450℃,催化剂氢效8.29g/L,选择性97.2%。A six-channel fixed-bed high-throughput reactor was designed and the hydrogenation of anthraquinone was used as the test reaction to verify the feasibility.The results showed that the relative error of each parallel channel was less than 3%.And Pd/Al2O3 catalyst for anthraquinone hydrogenation was studied in this reaction system.Different Pd concentrations and calcinations temperature were investigated,under optimal Pd concentration 1.2 g/L and temperature 450℃,the catalyst hydrogen efficiency and selectivity were 8.29 g/L and 97.2%,respectively.
