摘要
Ｃｒ２Ｏ３／Ａｌ２Ｏ３催化剂用稀土助剂处理后，提高了其对脱氢反应的稳定性，并在此基础上进行了丙烷脱氢反应实验和宏观反应动力学研究。在温度８７３～８９３Ｋ，空速５１０ｈ１的反应条件下，丙烷脱氢转化率约为５０％，丙烯选择性约为９０％，其宏观动力学方程可用ｒＣ３Ｈ６＝ｋ（ｐＣ３Ｈ８－ｐ２Ｃ３Ｈ６／Ｋ）来描述。
The property of
Cr2O3/Al2O3 catalyst was improved by rareearth aids On this catalyst the experiment of propane
dehydrogenation was carried out and macrokinetics was studied At temperature of 873893K and
spacevelocity of 510 h1, the conversion rate of propane was about 50% and the selectivity for
propene was about 90% The macrokinetics equation was expressed as rC3H6=k(pC3H8-p2C3H6/K)
