abstract

in this research, the selective oxidation of benzene to maleic anhydride (man) in a fixed-bed reactor was studied. the gas phase catalytic oxidation of benzene was carried outin a laboratory scale fixed bed reactor on the catalysts, which were prepared having two different compositions on silica gel. the effects of temperature, flow rates of benzene and air, and catalyst type on the reaction selectivity were investigated at normal atmospheric pressure. the experiments were performed at the temperature range of 300°c to 375 °c, the space-time (w/fb0) range was from 1*106 to 2.5*106 g.sec/mole, and the air/ benzene weight ratio changes were between 16-51. experimental results show that the maximum conversion is obtained at 375°c, at the space-time 1.33*106 g.s/mol and at the benzene/air mol ratio 41.36 by using first catalyst. according to the experimental results, a difference between catalyst 1 and 2, it could not be seen. man conversion was observed for both catalysts and both catalysts are suitable for oxidation of benzene to man in a fixed bed reactor.

Modeling and Simulation a Catalytic Fixed Bed Reactor to Produce Ethyl Benzene from Ethanol

Ethyl benzene used increasingly each year is the raw material of producing styrene monomer. This substanceis produced from benzene alkylation with ethylene or ethanol, depending on the availability and cost of rawmaterials. In this study benzene alkylation in the presence of ethanol in a catalytic fixed bed reactor inthree states of isotherm, adiabatic and non-isotherm-non-adiabatic is mathemat...
