doi:10.1016/j.cjche.2023.03.015

摘要/Abstract

摘要： The development of intensification technology for spouted beds has become a current research focus, and an effective way to improve the efficiency of spouted beds is to reform their structure. Although numerous studies have been conducted on conventional beds, there are few reviews on the comprehensive application of intensification technology for spouted beds. In this paper, we comprehensively review the role of intensification technology in spouted beds for use in hydrodynamics, drying, desulfurization, pyrolysis, coating, biomass and waste gasification, and biomass drying from the perspective of experiment and simulation. Finally, potential problems and challenges in current spouted-bed research are summarized.

Abstract: The development of intensification technology for spouted beds has become a current research focus, and an effective way to improve the efficiency of spouted beds is to reform their structure. Although numerous studies have been conducted on conventional beds, there are few reviews on the comprehensive application of intensification technology for spouted beds. In this paper, we comprehensively review the role of intensification technology in spouted beds for use in hydrodynamics, drying, desulfurization, pyrolysis, coating, biomass and waste gasification, and biomass drying from the perspective of experiment and simulation. Finally, potential problems and challenges in current spouted-bed research are summarized.
