A recently filed patent (Publication Number: US20230313050A1) describes a catalytic cracking additive that can be used in the process of catalytic cracking of feedstock oil. The additive consists of a modified ß zeolite, a clay, and a boron-containing binder. The modified ß zeolite contains copper oxide (CuO) and phosphorus pentoxide (P2O5) and has a micro-activity index of at least 58. The boron-containing binder is composed of aluminum oxide (Al2O3) and boron trioxide (B2O3) and has a pH value of 1.0-3.5.

The catalytic cracking additive is formulated with specific weight percentages of its components. It typically contains 10-50 wt % of modified ß zeolite, 20-85 wt % of clay, and 5-35 wt % of boron-containing binder. The preferred weight percentages are 20-50 wt % for modified ß zeolite, 20-70 wt % for clay, and 10-35 wt % for boron-containing binder. The modified ß zeolite is further characterized by its copper oxide content (0.1-1 wt %) and phosphorus pentoxide content (1-15 wt %). It is also specified that the modified ß zeolite should have a micro-activity index of at least 58, preferably 60-70. The boron-containing binder is characterized by its aluminum oxide content (70-97 wt %) and boron trioxide content (3-30 wt %). It should have a pH value of 1.0-3.5, preferably 1.5-3.0.

The patent also describes a method for preparing the catalytic cracking additive. The method involves several steps, including mixing the components, adjusting the pH value, and drying and calcining the mixture. The specific conditions and ratios for each step are provided in the patent.

The catalytic cracking additive can be used in a catalyst composition along with a catalytic cracking catalyst. The catalyst composition typically contains 1-50 wt % of the catalytic cracking additive and 50-99 wt % of the catalytic cracking catalyst. The catalytic cracking catalyst itself consists of a molecular sieve, a clay, and a binder, with specific weight percentages provided in the patent.

The patent also covers a process for the catalytic cracking of feedstock oil using the catalytic cracking catalyst and the catalytic cracking additive. The catalytic cracking additive is used in an amount of 1-50 wt %, based on the total amount of the additive and the catalyst.

Overall, this patent describes a specific formulation of a catalytic cracking additive and provides a detailed method for its preparation. The additive can be used in the catalytic cracking process to enhance its efficiency and effectiveness.
