【摘要】 用气相色谱仪与二氧化碳激光器组成的微反应系统考察了磷铝分子筛对高级烷烃、烯烃和芳烃的催化裂解和加氢裂解反应,并以Y-7型硅铝分子筛作对照,证明磷铝分子筛作为加氢裂解催化剂很有特色,同时还证明这种与激光发生器组成的微反应系统对于研究石油加工过程的催化裂化很有好处。用色谱技术进行了程序升温脱附法测定磷铝分子筛及Y-7型硅铝分子筛的脱附活化能和脱附速率常数,表明这种方法快速、简便和可靠。更多还原

【Abstract】 A microreactor combined with a gas chromatograph and a carbon dioxide laserwas designed and used to study the reactive capacity of microporous crystallinealuminophosphate on catalytic cracking and hydrocracking of n-tetradecane,n-octadecene and naphthalene.The results are compared with those of zeoliteY,showing that the capacity of hydrocracking of microporous crystallinealuminophosphate is superior to that of zeolite Y.The desorption activity energy and desorption rate constant of the two cata-lysts were determined by temperature programming desorption method with agas chromatograph,indicating that this method is fast,simple and reliable.更多还原
