Abstract

The reaction kinetics of direct synthesis of ethylene to propylene on PdO-Re2O7/B2O3-Al2O3 in liquid solvent (heptane) was studied. Ethylene changes in the direct synthesis of ethylene to propylene are occurring in the following order: dimerization, isomerization and metathesis. The stage of dimerization and metathesis are kinetically controlled but the stage of dimerization is equilibrium. In direct synthesis of ethylene to propylene on PdO-Re2O7/B2O3-Al2O3 in liquid solvent was advantaged than the gas phase: the yield of by-products (C5+) is decreased when the process is in liquid solvent
