在温度580～640℃、压力0.1 MPa、原料气空速1000～6000 h-1条件下,采用Pt-Sn催化剂,在固定床积分反应器中进行了丙烷催化脱氢实验,建立了脱氢反应宏观动力学模型。根据实验数据,采用多元线性回归分析得到宏观动力学模型的参数,丙烷脱氢反应的活化能约为78.4 kJ/mol。经统计检验,结果表明所建立的丙烷催化脱氢宏观动力学方程是可靠的。

The experiment of catalytic dehydrogenation of propane on platinum-stannum catalyst was performed with integral fixed-bed reactor,under the reaction conditions of temperature of 580-640 ℃,pressure of 0.1 MPa and space velocity of 1000-6000 h-1.The rate equation on macro kinetics of catalytic dehydrogenation of propane was obtained.Through fitting experimental results,the parameters of macro kinetic were determined by the method of multiple liner regression.The activation energy of dehydrogenation of propane reaction was about 78.4 kJ/mol.The results of statistic test on macro kinetics model showed that the rate equation was rational and reliable.
