乙炔的选择性催化加氢

STUDY OF SELECTIVE HYDROGENATION OF ACETYLENE

本文考察了不同ｐＨ值下铜、银、金负载型催化剂对ＫＢＨ４催化放氢速率的影响；在同一ｐＨ值下，对乙炔在各催化剂上的加氢过程的动力学行为进行了初步探讨，从而进一步证实乙炔的原子态氢加成的活性中心是零价的金属催化剂表面。

In this paper,the effects of metal catylysts such as Cu、Ag、Au on the dehydrogenation rate of KBH4 have been studied,and catalytic hydrogenation kinetics of acetylene on the surface of Cu、Ag、Au has been discussed at the same pH value.In this way,the demonstraction of the hydrogenation reaction taking place on the surface of zero valent metal catylysts is further confirmed.
