Kinetic Study for Hydrocracking of Heavy Oil in CSTR

In addition, deeper physicochemical knowledge is required to establish a proper deactivation function however, if reacting conditions in laboratory (pressure, temperature, H2/oil ratio, space velocity) are similar to those at pilot or industrial scale, then a time-dependent deactivation rate is useful to model the reaction kinetics. On the other hand, this deactivation function cannot be extrapolated to different operating conditions and, consequently, new deactivation function parameters should be proposed for each different operating condition. 

In this section, a five-lump kinetic model and a time-dependent nonselective catalyst deactivation expression are used to represent the reactions occurring during hydrocracking of heavy oils.
