Abstract
Many experimental trickle-bed reactors are operated at high temperatures and high pressures with volatile feedstocks which undergo partial vaporization of the liquid phase. The effect of this partial vaporization on the rate of reaction is demonstrated. The hydrodesulfurization of benzothiophene was simulated with the feed consisting of 5%, by weight, benzothiophene and 95% solvent. The pressure was held constant at 68 atm and temperature varied between 546 to 606 K employing isothermal simulations. The results show that the choice of solvent can significantly affect the rate of reaction.
