Effect of Operating Conditions on Divinylbenzene Production in Diethyl Benzene Dehydrogenation Reactor

Diehylbenzene (deb) dehydrogenation reaction was conducted to produce divinylbenzene (dvb) and ethylvinylbenzene (evb). the effects of temperature, catalyst weight, and time factor on the performance of the dehydrogenation reactor were investigated experimentally. temperature varied from 550 ºc to 600 ºc. temperature affects the conversion of deb to dvb significantly. by increasing the temperature from 550 ºc to 580 ºc, the mole fraction of deb at the outlet of the reactor is decreasing; however, a further increase in temperature up to 600 ºc does not decrease the mole fraction of deb at the outlet of the reactor. catalyst weight varied from 10 g to 40 g. the results showed that the trends of evb+dvb production and deb consumption were identical at various catalyst weights. to obtain an optimum time factor for the deb dehydrogenation process, experiments were conducted at various time factors. the results showed that the optimum time factor for dvb as the desired product was 825 g/h.mol. the data and information provided in this research can be used for scale-up and optimization purposes.
