Title:
【発明の名称】流動床法における粒状材料の処理方法ならびにこの方法を行うための反応容器およびプラント
Document Type and Number:
Japanese Patent JP2000510908
Kind Code:
A
Abstract:
In a method for treating particulate material in the fluidized bed method, the particulate material is maintained in a fluidized bed by a treating gas flowing from bottom to top and thereby is treated. To minimize the consumption of treating gas and to reduce entrainment of fine particles by the treating gas, a particulate material having a wide grain distribution and a relatively high portion of fines is used for treatment and the treating gas in the fluidized bed is maintained at a superficial velocity less than the velocity required for fluidizing the largest particles of said particulate material.
