APPARATUS FOR FLUIDIZED-BED REACTIONS

摘要

The invention provides an improved vessel for fluidized-bed reactions, characterized by the provision of metal or nonmetal projections of various shapes at calculated intervals on the internal sidewall of the vessel. The improved vessel results in a substantially reduced wear of the internal wall of the fluidized-bed vessel without detracting from the heat-exchange efficiency between the internal wall and the exterior of the vessel.
