Investigation of diethylbenzene (DEB) dehydrogenation reactor performance at different temperature, catalyst weight and time factor: An experimental approach

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 was varied from 550º C up to 600 º C. By increasing the temperature from 550 º C to 580 º C, the mole fraction of DEB in the outlet of the reactor is decreasing, but further increase in temperature up to 600 º C does not decrease the mole fraction of DEB in the outlet of the reactor. The results showed that the trends of EVB+DVB production and DEB consumption are identical at various catalyst weights. To obtain 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 a desired product is 825 gr/hr.mole. . The data and information provided in this research can be used for scale-up and optimization purposes.
