An Algorithm for Predicting the Hydrodynamics and Mass Transfer Parameters in Slurry Bubble Column Reactors for Fischer-Tropsch Synthesis

摘要

Since its discovery in 1920's, Fischer-Tropsch synthesis (FTS) has been carried out in a fixed bed reactor (ARGE), a circulating fluidized bed (Synthol), and a "Fixed Fluidized bed" reactor, which is commercially known as the "Sasol Advanced Synthol Reactor" (SASR). Slurry bubble column reactors (SBCRs) for Fischer-Tropsch synthesis were reported to have several advantages over fixed bed reactor technology. For instance, SBCR enjoys a much higher "online factor" when compared with the ARGE reactor, which operates in short cycles due to catalyst deactivation and the consequence drop of wax yield and quality. Also, recent studies have shown that the SBCR is the most cost effective FTS technologies directed towards the production of middle distillates.
