Kinetics of the Catalytic Vapor Phase Reduction of Nitrobenzene

摘要: The kinetics of the catalytic vapor phase reduction nitrobenzene to aniline over copper-magnesia catalyst in temperature range from 175°C 220°C was studied using a differential reactor. rate reaction measured at atmospheric pressure with high mole ratio hydrogen nitrobenzene. From analysis experimental data, it concluded that rate-controlling step adsorption process on surface. According Langmuir-Hinshelwood mechanism, final equation r for obtained as follows;r=kPH/1+KNPN+KAPA+KWPWwhere k; constantPH, PN, PA and PW; partial hydrogen, nitrobenzene, waterKN, KA KW; equilibrium constant waterThis will be useful if can used predict wide reactions hence, suitable reactor design.
