一、前言用脉冲微反色谱数据求一级反应动力学参数,可用Bassett 方程。对于反应物或/和产物在催化剂上有较强吸附的情况,色谱峰严重拖尾,给测量带来困难。为解决这类问题,Lane 和Phillips 曾提出用断流气相色谱法。近年臧雅茹等曾用微型断流催化色谱研究了醇类脱水反应动力学。他们都采用氢焰离子化检测器。本文采用脉冲微反—断流色谱联合装置,以热导池为检测器,研究了TNZ—Y 分子筛上异丙苯裂解反应动力学。
First, the foreword Using pulsed micro-chromatography data to find a reaction kinetic parameters, available Bassett equation. For reactants or / and products with strong adsorption on the catalyst, the chromatographic peak is severely tailored, making it difficult to measure. To address this type of problem, Lane and Phillips proposed using a cut-off gas chromatograph. In recent years, such as Zang Yaru micro-cut catalytic chromatography has been used to study the alcohol dehydration reaction kinetics. They all use hydrogen flame ionization detectors. In this paper, pulsed micro-reverse-flow chromatography combined device, with the thermal conductivity of the pool as a detector to study the TNZ-Y zeolite cleavage reaction kinetics.
