Research Proggress on the Influence of Internals on Gas-Solid Flow Characteristics in Riser
The natural characteristic of non-uniform distribution of gas-solid along axial and radial direction in the riser is an important factor affecting gas-solid contact efficiency and reaction selectivity.This paper provides a review of experimental research on the effect of internal components on the particle concentration distribution,gas-solid mixing and heat transfer behavior along axial and radial directions in a riser.The research results show that the appropriate internals can improve the gas-solid distribution,improve the gas-solid mixing,mass and heat transfer effect,and help to improve the reaction rate and selectivity.
