The apparent kinetic model of the hydrogenation of the alkylation reactor effluent mixture for removal of olefin impurities was studied. Hydrogenation experiments over Pd/Al2O3 catalyst were carried out. On the basis of reactor phase structure, the characteristic equation of the reactor was determined. The apparent kinetic model equation of olefin conversion was determined. By thermodynamic analysis, the mathematical models of the hydrogen solubility coefficient and hydrogen solubility were determined through the correlation of hydrogen solubility coefficient with temperature and the molar mass of the liquid medium. The apparent kinetic model of olefin hydrogenation was established through model parameter estimation. The order of hydrogen concentration in liquid was close to 1, and the order of olefin was significantly higher than that of hydrogen. The olefin concentration had greater influence on the hydrogenation reaction rate than hydrogen. There was an hydrogenation activity distribution of olefin mix...
