METHOD FOR FEEDING POWDERY CATALYST

摘要

PROBLEM TO BE SOLVED: To minimize an amount of associated fluid to feed intermittently a powdery catalyst to a reactor while changing continuously or uniform by the concentration of the powdery catalyst which discontinuously exists in the associated fluid, from a catalyst feeder. SOLUTION: This method for feeding the powdery catalyst to the reactor while making the concentration of the powdery catalyst uniform to the flow direction has a means for temporarily retaining the flow of the powdery catalyst which intermittently flows accompanied by the fluid in the course of the flow path.
