Abstract
Modeling of hydrocracking is a challenging task due to the large number of species and complex reactions involved. Authors present a dynamic, non-isothermal reactor model, constructed using the method of continuous lumping which treats the complex reactive mixture as a continuum.
The model characterizes concentrations in terms of reactivity, which is a monotonic function of the true boiling point of the mixture. They develop material and energy balances in the form of integro-differential equations. They identify and estimate significant modeling parameters using data from an industrial reactor.
