Abstract:Solids inventory is a critical parameter for catalytic reactors: it impacts the geometrical configuration of the reactor, compressor/blower requirements, and the overall economics of the process. Although significant advances have been made for characterizing the hydrodynamic regimes in gas-solid fluidization, empirical relationships for predicting the solids inventory in risers are largely in the developmental stages. Empirical models are either based on the slip velocity, slip factor or the Richardson-Zaki b… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
