发明名称 Fluidization aid including low bulk density fluidization aid
摘要 Tendrillar carbonaceous material is used as a fluidization aid for fluidized beds. The tendrillar carbonaceous material can be used to fluidized cohesive solids. Further, it can be used to improve fluidization of particulate solids by reducing entrainment, eliminating bubbling, and/or eliminating channelling. The tendrillar carbonaceous material can be a fibrous, particulate carbonaceous material comprising carbon fibers and a ferrous group metal component dispersed throughout the carbon fibers as nodules. The tendrillar carbonaceous material has a bulk density of from about 0.01 to about 0.7 g/cm3 and comprises an agglomeration of tendrils having a diameter of from about 0.01 to about 1 micron and a length to diameter ratio of from about 5:1 to about 1000:1.
