Preparation of CeO2/SiO2 and Kinetics of Isomerization of Butene
Catalysts, CeO2/SiO2, were prepared by the impregnated method. The activity of the catalysts at calcination temperature of the catalysts in the range 300-500 ℃ was constant and decreased at 600℃. The catalystic activity in the range of ratio of CeO2 to SiO2, 1/5-1/32, increased linearly. The reaction order with respect to t-2-butene or c-2-butene was first proximate1y at low partial pressures of t-2-butene or c-2-butene.At higher partial pressures of t-2-butene or c-2-butene the kinetics of isomerization of 1-butene. The kinetic parameters were estimated by methods of ortho nal design. The estimated values of adsorption of 1-butene, t-2-butene and c-2-butene are coincided with the experimental values by the pulse method.
