Webb20 juli 2024 · 1. Introduction. Bubble columns are often used as gas-liquid reactors, especially for reactions with slow kinetics such as oxidation, chlorination, alkylation, hydroformylation, hydrogenation, Fischer-Tropsch synthesis, coal liquefaction, desulfurization and fermentation (Chaumat et al., 2007, Ranade, 2002).These reactors … http://www.iaeng.org/publication/WCECS2007/WCECS2007_pp163-168.pdf
Webb28 mars 2013 · Numerous experimental and computational studies have been performed to investigate the flow behavior of bubble column reactors for a proper design and scale-up. Experimental techniques vary from simple visual observation to more advanced noninvasive diagnostic techniques. Bubble column reactors are used in various types of chemical reactions like wet oxidation, or as algae bioreactor. Since the computerized design of bubble columns is restricted to a few partial processes, experience in the choice of a particular type column still plays an important role. Visa mer A bubble column reactor is an apparatus used to generate and control gas-liquid chemical reactions. It consists of a vertically-arranged cylindrical column filled with liquid, at the bottom of which gas is inserted. Visa mer The introduction of gas takes place at the bottom of the column and causes a turbulent stream to enable an optimum gas exchange. Numerous … Visa mer • Modeling of mass transfer characteristics of bubble column reactor with surfactant present Visa mer Bubble column reactors belong to the general class of multiphase reactors which consist of three main categories namely, the trickle bed reactor (fixed or packed bed), fluidized bed reactor, and the bubble column reactor.
