A pilot plant study and 2-D dispersion-reactor model for a high-density riser reactor

摘要: The radial concentration profiles of reactant concentrations in a pilot plant high-density riser propylene ammoxidation reactor were sampled and analyzed the extreme maldistribution found. A two-dimensional dispersion-reactor model was proposed to simulate selective oxidization that taken place riser, which considered influences axial lateral gas mixing, non-uniformity solids gas-velocity on reactor. can successfully predict plant. Simulation results indicate catalyst distribution as well insufficient mixing result significant loss selectivity yield acrylonitrile. scale-up effect interdependence reaction rate, requirement are discussed details.
