In the design of a chemical process, both chemical thermodynamics and chemical kinetics matter. The article is devoted to solving the problem of finding the relation between these approaches. The effects of the nature and composition of solvents onto the thermodynamic characteristics of the adsorption states of hydrogen adsorbed on nickel and onto the activity of the nickel catalyst were studied. For these purposes, the following was done: (i) differential heats of hydrogen adsorption in a wide range of surface coverage and maximum quantity of adsorbed hydrogen were determined by adsorption calorimetry on partially deactivated nickel catalyst from solutions; (ii) the activity of the catalyst for the corresponding systems was measured from kinetic experiments. The correlation between a catalyst activity and an adsorption energy distribution of hydrogen adsorbed was reported, it will subsequently predict the activity of the catalyst without experiment.

水溶液中镍催化剂的氢吸附分布函数与马来酸二钠加氢活性的相关性

在化学过程的设计中，化学热力学和化学动力学都很重要。本文致力于解决发现这些方法之间的关系的问题。研究了溶剂的性质和组成对吸附在镍上的氢的吸附状态的热力学特性以及镍催化剂活性的影响。为了这些目的，进行了以下操作：（i）通过在部分失活的镍催化剂上通过吸附量热法测定溶液在广泛的表面覆盖范围内的氢吸附差热和最大的氢吸附量；（ii）通过动力学实验测量催化剂在相应系统中的活性。
