摘要: Abstract The functioning of the riser catalytic cracking units was simulated using a new kinetic model reactions and an accurate description gas catalyst hydrodynamics in section. is based on molecular hydrogen transfer reactions. It may be seen as intermediate between simple lumping cuts ‘single events’ method. Chemical lumps, such alkanes, alkenes, cycloalkanes, alkenic cycloalkanes aromatics, are defined different cuts. Kinetic constants determined from experimental results obtained laboratory scale tubular reactor (M.A.T). data solid flow assessed by various techniques: isokinetic sampling, Pitot probe, γ-ray tomography tracing cold set-up or industrial risers. were compared with yields.
