Kinetics deep desulfurization

The objective of this process is the deep desulfurization of middistillate types of feedstocks. Exxon licensed hydrotreating units in the past, but decided that a new technology had to be developed for deep desulfurization of diesel oil. Main differences from the existing technology is the different desulfurization kinetics for deep desulfurization and the importance of a good... [Pg.108]

The effect on catalyst activity of process variables such as LHSV, temperature, hydrogen partial pressure, hydrogen sulfide partial pressure and gas/oil ratio can be predicted by a suitable kinetic expression. It was found that the expression shown in equation 1 could be used to describe the kinetics of CoMo and NiMo catalysts for very deep desulfurization of diesel. ... [Pg.300]

Reactions that require elimination of trace quantities of certain compounds (hydro-desulfurization reactions in refineries, deep hydrogenation, or other intrinsically slow reactions) are normally kinetic controlled. The trickle bed reactor in the cocurrent downflow mode is a popular multiphase reactor for such apphcations. The... [Pg.49]
