Bubbling reactor
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. See more 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. See more The introduction of gas takes place at the bottom of the column and causes a turbulent stream to enable an optimum gas exchange. Numerous forms of construction exist. … See more • Modeling of mass transfer characteristics of bubble column reactor with surfactant present See more Bubble column reactors belong to the general class of multiphase reactors which consist of three main categories namely, the trickle bed … See more WebJan 27, 2024 · For instance, Steinberg [22] proposed in 1999 a reactor concept which consisted of a molten metal bath of tin/copper, in order to promote the heat transfer from the bath to the upcoming methane (upwards) in a bubbling reactor configuration. He pointed out its benefits in terms of carbon separation, which would be placed on top of the molten ...
