Preparation of catalyst by spray evaporation method
Jun 26, 2017

Catalyst for producing fluidized bed with particle diameter of tens of microns to hundreds of microns. Such as m-xylene ammoxidation system between two fluidized bed dichlorobenzonitrile catalyst manufacturing, first given the concentration and volume of vanadate and chromium salt solution mixing, then silica gel mixed with new quantitative system, the pump into the spray dryer, the nozzle, water flow in the dry in the hot air. The material is formed microsphere catalyst, drawn from the bottom of continuous spray dryer.
