PP-<strong>III</strong>-71Operation at high volumetric rates leads to decrease of reactor overall dimensions and toinvestments lowering.For optimization of reactors of propane catalytic dehydrogenation with fluidized catalystbed mathematical model of reactor was developed. It takes into account features ofhydrodynamics and thermophysics of fluidized bed sectioned with horizontal grids and withdirected catalyst circulation. Process scheme provides for maximum using of heat streams.Process meets the strictest environmental requirements. Comparing with world knowncommercial processes the new one requires less construction investments. The technologyallows using high-power units (more than 400 000 MTPY of propylene).At OAO NII “Yarsintez” there is catalyst production for fluidized bed dehydrogenationprocesses with capacity of 1000 MTPY.603
