FCC riser; Computational fluid dynamics (CFD); Cracking reaction kinetics; Hydrodynamics; 4-Lump kinetic model; k-Epsilon turbulence model Abstract Fluid catalytic cracking (FCC) is an essential process for the conversion of gas oil to gasoline. This study is an effort to model the phenomenon numerically using commercial computational fluid dynamics (CFD) software, heavy density catalyst and 4-...

the catalytic cracking of a fuel oil over fluid catalytic cracking (fcc) catalyst has been investigated applying different additives. catalyst mixtures consisting of a equilibrium fcc catalyst (e-cat) blended with zsm-5, mcm-41 and mordenite additives were examined at the additive levels of 25 wt.%. the catalytic performance of the matrix was studied in a fixed bed micro-activity test unit (mat...

Gas-particle flows are involved in various industrial applications in the energy, oil and gas fields, like coal gasification, production of light hydrocarbons by fluid catalytic cracking, catalytic combustion and different treatments aiming to reduce or eliminate pollutants. In addition, gas-particle flows take part to interesting natural phenomena, like volcanic eruptions, and their understand...
