Unresolved Questions and Future Research

The following are some issues that are still necessary to investigate  

The exact nature of model parameters and their explicit correlation with the activity and composition of catalyst. Correlating model parameters of the continuous kinetic approach against operation variables could be a good approach although empiric. 

The possibility of better resolution of the model by addition of new peaks to the yield distribution function (multimodal distribution) that, in addition to hydrocracking continuum description, can also give more information on the mechanism of such a process. 

Modeling of Processes and Reactors for Upgrading of Heavy Petroleum 

It is necessary to explore the multiplicity of solutions of the model and the validity of extrapolation for predicting the maximum boiling point, although this last fact could not be a critical issue.
