- W1762722720 abstract "Abstract In this study, a series of PtSnK/Al 2 O 3 catalysts were prepared by an impregnation-reduction method and employed as a catalyst in an isobutane dehydrogenation reaction. In order to improve the dehydrogenation performance of isobutane, the preparation conditions of the PtSnK/Al 2 O 3 catalysts were optimized by the Taguchi method of experimental design. The effects of four variables, mass ratio of platinum to tin, concentration of H 2 PtCl 6 , calcination temperature, and K loading (mass fraction) at four levels were investigated. The results revealed that the order of the affecting factors was mass ratio of platinum to tin > K loading > calcination temperature > concentration of H 2 PtCl 6 . The optimum preparation conditions were as follows: mass ratio of platinum to tin 1:1, concentration of H 2 PtCl 6 7.72 × 10 −4 mol/L, calcination temperature 500 °C, and K loading 0.8%. The optimized PtSnK/Al 2 O 3 catalysts exhibited good catalytic performance for isobutane dehydrogenation. The average isobutane conversion, selectivity toward isobutene, and deactivation parameter were 46.59 ± 0.83%, 95.37 ± 0.49%, 1.45 ± 0.74%, respectively." @default.
