Technical progress of uidized-bed reactor
Abstract:Coal gasication and catalytic cracking of petroleum are
representatives of recent industrial applications of uidization Current
theoretical studies of uidized bed reactor technologies are focused on
quantitative prediction and optimum control , involving multi—scale
heterogeneous structures consisting of gas bubbles , particle
agglomerates , and liquid drops distributed in size and in concentration ;
modeling for predicting relationships between heterogeneous structure and
transport of momentum , heat , mass , as well as chemical reactions ; and
puter simulation for the prediction and optimization of process operation and
scale—up for uidized bed reactor technologies in the process
industries , such as chemicals , metallurgy , energy , new materials,
pharmacy, foodstu', and environment.
Key words: Fluidized-bed reactor; uidization; technologies; application
