Computational fluid dynamics based design of downers with the implementation of detailed chemistry Ghent University
Fluid catalytic cracking (FCC) is one of the major conversion technologies in the oil refinery industry and produces the majority of the world’s gasoline. FCC Is conventionally performed in a circulating rising fluidized bed reactor, however, the usage of down-flow reactors offers several advantages such as less species back-mixing and more narrow residence time distributions. Experimental studies have shown that in both riser and downer ...
