3-甲基吡啶氯氟化反应积炭失活催化剂的烧炭动力学模型
Kinetic Models for Coke Combustion of Deactivated CrO-Al from 3-Picoline Chlorofluorination Reaction
摘要
Abstract
TPO-MS was used to characterize deactivated CrO-Al catalysts from chlorofluorination of 3-picoline. Results indicate that coke formed on the catalysts is composed by carbon, hydrogen and nitrogen. The coke can be removed when temperature reaches to 500℃. TG results show the combustion behavior of the deactivated catalyst CrO where coke mass increases and coke species change from light to heavy ones when reaction time increases. Therefore, two models are proposed to describe the combustion behavior of the catalysts after reacting for 5 h and 10 h, respectively. The developed kinetic models are in good agreement with experimental results and the linear correlation coefficient is over 0.97.关键词
