研究了乙炔加氢制乙烯Pd/Al_2O_3催化剂钯含量及助剂与起始反应温度及反应温度、加氢活性和选择性之间的关系.在此基础上研制出高选择性(≥98%)的CHC-1型催化剂.500h连续实验结果表明:其活性、选择性均稳定.
The relationship between the palladium content of Pd / Al 2 O 3 catalyst and the initial reaction temperature, reaction temperature, hydrogenation activity and selectivity of hydrogenation from acetylene to ethylene was studied. On the basis of this, high selectivity (≥98%), Of CHC-1 type catalyst .500h continuous experimental results show that: its activity and selectivity are stable.
