| Abstract: | The intrinsic kinetic behavior of acetic anhydride hydrogenolysis to vinyl acetate via syngas is investigated over a 5wt% palladium/active carbon catalyst. The kinetic model is shown as -dN AdW R=7 32×10 7×exp(-5 76×10 4R·T)×p 0 11 A×p 0 057 (H 2) (molkg·h) Abstract: The result of the study provides a scientific basis for enlarging and designing in the future. |
