Abstract
A kinetic model for a catalytic cracking riser reactor is stored in a computer for simulating a hydrocarbon cracking reaction. The stored model describes a reactants, an intermediate, and a product species, which are lumped according to boiling range. Reaction rate constants for cracking the individual components of the lumping scheme are functions of a statistical technique known as "principal components," which are in turn linear combinations of bulk properties characterizing both catalyst and oil and are based on historical operating data for the riser reaction.
