Some literature on collective dynamics Fdfcc

Thread Content

In recent years, while there is a demand for clean gasoline produced by catalytic cracking with low levels of olefins and aromatics, there is also a pursuit of chemical feedstocks that yield large amounts of propylene and butylene to achieve maximum economic benefits. Therefore, the optimized design and operation of the device have become increasingly important. The FDFCC process features two independent lift tube reactors, and to optimize this process, both reactors must be optimized. In the FDFCC process, the purpose of the heavy oil riser reactor is to convert heavy oil. Through extensive research efforts, many kinetic models for the catalytic cracking of heavy oil have been developed and used to guide the design and operation of industrial plants. The gasoline riser reactor in the FDFCC process is primarily used to modify gasoline and increase the production of chemical feedstocks such as propylene. To optimize gasoline riser reactors, it is urgently necessary to study the secondary reaction kinetics of catalytic cracking gasoline. The secondary reactions of catalytic gasoline involve hundreds of compound molecules, with multiple reactions being highly interconnected. Discussing only a few typical reactions such as hydrogen transfer and isomerization is insufficient to elucidate the reaction mechanism of the entire process, nor can a complete kinetic model of the process be established. At the same time, the conventional methods for solving kinetic models of complex reaction systems are far from sufficient to meet the practical needs of analyzing the complex network associated with gasoline secondary reactions. Based on the experimental data and characteristic analysis of the secondary reactions of catalytic cracking gasoline, this chapter will develop a kinetic model for these secondary reactions using a lumped kinetics approach, in order to predict the PONA composition of the gasoline. A hybrid genetic algorithm is then used to solve the model, thereby laying a foundation for the kinetic analysis of the secondary reaction process in catalytic cracking gasoline.
