Abstract
A promoted gamma-Al2O3 catalyst impregnated with 7 wt% HCl and 7 wt% H 3BO3 has been recommended for the manufacture of diphenylamine (DPA) f rom aniline in vapour phase process. The catalyst selection has been b ased on the comparison of activity and selectivity among gamma-Al2O3 c atalysts treated with different chemicals. It has been observed that H 3BO3 has the characteristics of arresting the rapid deactivation of ga mma-Al2O3 catalyst and improving the DPA selectivity. A kinetic model based on dual site adsorption has been found suitable for kinetics of the catalytic system.
