As the demand for light olefins increases and the oil becomes heavier, higher requirements for catalytic activity, anticoking performance, and stability of catalyst have been brought forward. Basic catalyst has attracted much more attention in recent years due to its excellent performance in heavy oil utilization. This review highlights the research progress of catalytic cracking over basic catalyst for olefin production and heavy oil utilization. The catalytic mechanism along with attractive functions of basic catalyst are summarized. The optimized condition of operation is discussed as well. Several processes and technologies of catalytic cracking over basic catalyst are introduced to advance future development. This review attempts to benefit new researchers in this field by helping them to understand basic-catalyzed cracking characteristics for preparing a suitable catalyst.

“…The traditional steam cracking process can provide abundant C4 olefin resources, but it has the outstanding defect of large energy consumption. The catalytic cracking process [3] can only produce a small amount of C4-olefin resources. Given the above problems, when studying the relationship between ethanol conversion, C4 olefin selectivity, and temperature, Wang et al conducted thermodynamic calculations [4] to analyze the equilibrium conversion of ethanol, the equilibrium uptake rate of ethylene, the equilibrium uptake rate of ether, and the equilibrium uptake rate of C4 under different reaction temperatures, pressures, and water-alcohol ratios.…”

“…The process is designed to maximize olefin production while lowering the fuels products yields. Due to the high conversion and selectivity, this technology is considered to be the key technology for future refineries 2 . In general, the high‐quality feedstock for the catalytic pyrolysis to chemicals process is paraffin‐based petroleum, rather than naphthene‐based.…”

Petroleum catalytic pyrolysis to light olefin technology has received wide‐ranging research interest in the refining industry. This work built a molecular kinetic model for the catalytic pyrolysis of a heavy gas oil from bitumen synthetic crude oil (SCO) to light olefins. A feedstock compositional model was constructed containing 1311 molecules using bulk properties information. A variety of reaction rules was summarized and digitized, and from which, a reaction network involving 2631 substances and 6793 reactions was generated via a reaction network autogeneration algorithm. The reaction network for the catalytic pyrolysis was transformed into reaction rate equations. Systematical pilot‐scale catalytic pyrolysis experiments were carried out, which were used to regress the molecular kinetic model parameters. The tuned model is able to predict the product yield and molecular distribution. Moreover, a range of sensitivity analysis was performed, revealing the dependence of light olefins yields on the reaction conditions.
