摘要：本实验选择了乙烯裂解装置副产脱除异丁烯后的剩余碳四作为原料。分别在1050℃和900℃温度下焙烧4小时制得两种载体A,B，并用含Pd的金属盐溶液进行浸渍。把两种催化剂在实验评价装置上进行评价得出焙烧温度为1050℃的载体A对1-丁烯的选择性较好。继而开始用载体A测定活性组分含量对催化剂性能影响，实验数据表明浸渍0.28（m/m）%的Pd所得到的催化剂是醚化后裂解碳四选择性加氢脱丁二烯制高纯度1-丁烯合适的催化剂。24423
用上述催化剂进行工艺操作条件的研究，针对不同温度，压力，空速，氢比分别进行了几组实验。工艺操作条件研究结果表明，该催化剂的合适工艺操作条件为：压力1.5MPaG~2.0MPaG，温度为50℃~80℃，空速为10h-1，氢比为3mol/mol。
最后为了检验催化剂各种性能的稳定性进行了500小时的稳定性实验。得出结论丁二烯的转化率、1-丁烯的收率均达到指标要求，说明该催化剂的加氢活性及选择性均具有良好的稳定性。

Mixed C4 selective hydrogenation of butadiene removal system 1-butylene catalysts
Abstract : This study selected the ethylene cracker unit byproduct removal of residual carbon after four isobutylene as a raw material .After calcining 4 hours , respectively to obtain two vectors A, B at a temperature of 1050 ℃ 900 ℃, and impregnated with a solution containing Pd metal . The two catalysts in the experimental evaluation of the evaluation means to selectively draw the firing temperature of the carrier A 1050 ℃ preferably 1-butylene . Then start the measurement of the active ingredient content on catalyst performance carrier A, experimental data show that the catalyst impregnated 0.28 (m / m)% of Pd is obtained after ether cleavage selective hydrogenation of carbon four high purity de- butadiene system 1-butylene suitable catalysts.
Research conducted by the above process conditions the catalyst for the different temperature, pressure, space velocity and hydrogen ratio were carried out several experiments . Process operating conditions results show that the catalyst suitable process operating conditions are as follows: pressure 1.5MPaG ~ 2.0MPaG, the temperature is 50 ℃ ~ 80 ℃, space velocity 10h-1, hydrogen ratio 3mol/mol.
Finally, to test the stability of various properties of the catalyst stability experiments conducted for 500h . Concluded that the conversion of the butadiene , 1-butylene closing rate reaches the indicator , indicating the hydrogenation activity and selectivity of the catalysts have good stability.
