TWO-ZONE FLUIDIZED BED REACTOR (TZFBR) AS A POTENTIAL TOOL FOR PROCESS INTENSIFICATION IN CATALYTIC REACTIONS

摘要

The state-of-art of Two-Zone Fluidized Bed Reactor (TZFBR) technology is here reviewed. TZFBR potentials and hurdles are discussed. Recent advances in the TZFBR field and some experimental applications in gas-solid catalytic reactions are presented. These examples illustrate the reactor performance in processes where catalyst coking represents a thread for the process feasibility and in catalytic oxidations where the separation of the catalyst oxidation and the catalyst reduction can provide some advantage.
