To represent the catalytic cracking of heavy oil with steam over a zirconia-alumina-iron oxide catalyst, a kinetic model was proposed. The model includes four lumps: heavy oil (boiling point above 350℃), gas oil (boiling points of 250-350℃), gasoline + kerosene (boiling point less than 250℃), and gas. In this reaction, heavy oil fractions reacted with the lattice oxygen in the iron oxide. Active oxygen species generated from steam were incorporated into the iron oxide lattice, and these species reacted with heavy oil fractions. As a result, lighter fractions and carbon dioxide were mainly produced with almost no coke. Kinetic parameters were determined by nonlinear least-square regression of the experimental results. The predicted product distributions were found to be in good agreement with the experimental data.
