Dehydrogenation of propane was performed on alumina-supported platinum catalysts, catalyst deactivation by coking and deactivation rate was studied. The reaction was conducted at 600 oC, ambient atmosphere, and nitrogen: propane had a molar ratio of 4.3: 1. The method of catalyst preparation was incipient wetness impregnation, and the platinum loading on mesoporous Al2O3 was 0.5, 1.0, 2.0, and 3.0 wt.%. Characterization of catalyst was measured by N2 sorption (BET) and TGA technique. Higher platinum loading leads to higher conversion, higher propylene selectivity, and higher deactivation rate. |
