摘　　要：甲醇重整制氢是实现氢能产业化应用的重要发展方向,催化剂作为甲醇重整制氢系统的核心材料,其性能和寿命至关重要。本文选用商业Cu/ZnO/Al_(2)O_(3)催化剂为研究对象,研究了Cu基催化剂反应10h、100h、1000h后的性能,分析了甲醇在不同催化温度下的反应速率,并创新性地提出催化剂寿命的评价和预测方法。系统研究高温失活对Cu基催化剂性能的影响分析,通过对催化剂比表面积、Cu晶粒分散度以及热重(TG-DTG)表征分析,发现高温烧结和积炭是甲醇水蒸气重整反应中导致Cu基催化剂失活的主要原因。该研究对开发设计长寿命甲醇重整制氢系统具有重要意义。Methanol reforming for hydrogen production is an important development direction to realize the industrial application of hydrogen energy.As catalyst is the core material of methanol reforming,it’s performance and life are very important.In this paper,the performance of Cu-based catalysts of commercial Cu/ZnO/Al_(2)O_(3)were studied with reaction for 10h,100h,1000h,the reaction rates of methanol at different catalytic temperatures were analyzed,and the evaluation and prediction methods of catalyst life were innovatively proposed.The influence of high temperature deactivation on the performance of the Cu-based catalyst was systematically studied.Through the characterization of catalyst’s specific surface area,Cu grain dispersion and TG-DTG,we found that high temperature sintering and carbon deposition were the main reasons for the deactivation.This research held significant importance for the development and design of long-life methanol reforming system for hydrogen production.
