heal.abstract	Two-phase flow, heat transfer, and reaction in fluid catalytic-cracking riser-type reactors are studied using a 3-D mathematical model. This study was carried out based on the model of Theologos and Markatos, which incorporates a detailed ten-lump reaction kinetics scheme and accounts for gradual feedstock vaporization inside the reactor. Predictions obtained using the new model are compared against industrial reactor operating data. A design study was also carried out to illustrate that the model developed is capable of predicting feed-injector geometry effects on overall reactor performance. It shows that by increasing the number of feed-injection operating nozzles at the bottom of the reactor, selectivity of primary products is improved.	en
