本文提供了在钯-纤维氧化铝上不可逆吸附乙炔加氢的试验结果。采用程序升温脱附与反应及恒温积分反应器研究反应动力学。参数的求得是通过建立在离散型基础上的、在小值范围内改变拉氏变换中的p 值来实现的。不可逆吸附乙炔在催化剂上有两个吸附部位,其中较弱的部位在室温加氢中只生成乙烷,而较强的吸附部位则在室温下无加氢活性,但在升温脱附时发生聚合。 This paper provides experimental results on the irreversible adsorption of acetylene on palladium-fiber alumina. The reaction kinetics was studied by temperature programmed desorption and reaction and constant temperature integral reactor. The parameter is obtained by changing the value of p in Laplace transform on the basis of the discrete type in the small value range. Irreversible adsorption of acetylene on the catalyst has two adsorption sites, of which the weaker part of the hydrogenation at room temperature only generate ethane, while the strong adsorption site at room temperature without hydrogenation activity, but the polymerization occurs when the temperature desorption .
