A new empirical kinetics of novel catalyst for high temperature water–gas shift (HT-WGS) at the pressure of 2.5 MPa was developed in the study. Using gradientless reactor a set of kinetics data for catalyst in form of 5 × 5 mm tablet operating at diffusion regime was collected, studied and fitted to classic power-law kinetic equation. Simple power-law equation fits the experimental data with sufficient accuracy. The reaction with respect to CO is close to first order and the apparent activation energy of ca. 51.5 kJ mol⁻¹. The equation is believed to be applicable to modeling of HT-WGS at the temperature in the range of 300–400 °C and the pressure ca. 2.5 MPa corresponding to synthesis gas production for ammonia and methanol plants.

研究了新型催化剂在2.5 MPa压力下的高温水煤气变换（HT-WGS）的新的经验动力学。使用无梯度反应器，收集，研究和研究了一组催化剂的动力学数据，这些催化剂以5×5 mm片的形式在扩散状态下运行，并进行了拟合，并符合经典的幂律动力学方程。简单的幂律方程可以足够准确地拟合实验数据。关于CO的反应接近一级，并且表观活化能约为1。51.5 kJ mol ^-1。该方程被认为适用于在300–400°C的温度范围内和压力ca的HT-WGS建模。2.5 MPa，对应于氨和甲醇装置的合成气产量。
