Characterization of the Contact between Liquid Spray Droplets and Particles in a Fluidized Bed

摘要: The injection of a gas−liquid spray jet into fluidized bed particles is used in many applications such as fluid catalytic cracking or coking. In uniform contact the liquid droplets and entrained essential for high yields. objective this study to measure quality solid−liquid mixing when injected coke particles. A quick method has been developed determine local on short time scale. measuring technique uses temperature characterize mixing. Cold ethanol via two-phase nozzle mixed with heated An assembly fast response thermocouples, located downstream jet, provides instantaneous readings over cross section at different axial positions along length jet. case perfect mixing, temp...
