摘要: Abstract A comprehensive conversion equation was developed to simulate the catalytic reaction conditions (include temperature, pressure, residence time, and composition) in tubular reactors: X M = 1 − exp [ ( + B / T r C ) p n 0 τ ∏ i m y ] . This is based on characteristics of power-exponential function as well “variable order” “virtual reactant” concepts. Its validity verified by fitting experiment data from three different systems such dehydrogenation diethyl benzene, hydrogenation ethylbenzene, hydrodesulfurization thiophene. The results show that influences reactant composition can be determined within a wide range values. By comparison with experimental data, calculated conversions were all found have total average relative deviation less than 2%. suggests not limited specific catalyst system but could suitable for various reactors.
