Many fluidized bed operations are physical in nature (e.g. drying, coating, classification, granulation, and rapid heat transfer as in quenching or annealing). Other operations involve chemical reactions including the cata lytic cracking of hydrocarbons, the manufacture of acry10nitrite and phthalic anhydride, the roasting of metallurgical ores, and the regeneration of spent catalysts. In recent years fluidized beds have been of special interest because of their potential as the central component in new processes for utilizing coal as a source of energy, notably in coal combustion and gasification processes. The fluidized bed offers a number of advantages over most other methods of contacting, in particular high rates of heat transfer, temperature uniformity and solids mobility. Among the disadvantages are particle losses by entrainment, attrition of solids, limited reactor efficiency due to gas bypassing and gas and solids backmixing, and difficulties in design an | | 出版日期 | Book 1980 | | 关键词 | Metall; dynamics; granular material; liquid; oleum | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4684-1045-7 | | isbn_softcover | 978-1-4684-1047-1 | | isbn_ebook | 978-1-4684-1045-7 | | copyright | Plenum Press, New York 1980 |
