Single step hydrocracking

Figure 8. Single Step Hydrocracking. Residue Recycle at 2nd Reactor.

In the final step, the waxy heavy paraffin is catalytically hydrogenated, isomer-ized, and hydrocracked in a single trickle-bed reactor over a proprietary catalyst to... 

The present paper has outlined an approach for the detailed kinetic modeling of both thermal cracking and catalytic hydrocracking. The parallelism between the two cases is remarkable. Expressing the rate equations in terms of elementary steps and single events of either radical or carbenium ion chemistry keeps the number of rate parameters within practical limits. The approach should stimulate the commitment of oil and petrochemical companies to the improvement and refinement of their analytical means.
