APPARATUS FOR STRENGTHENING GAS-LIQUID MASS TRANSFER OF BUBBLING BED HYDROGENATION REACTOR

摘要

An apparatus for strengthening the gas-liquid mass transfer of a bubbling bed hydrogenation reactor, mainly comprising a main body tube (1) and a filling tube (4) which is in communication with the main body tube (1), wherein oil is contained in the main body tube (1), and the filling tube (4) is used for filling surface active substances into oil in the main body tube (1). By filling a surface active substance into an oil, the surface tension from the two-phase interface can be remarkably reduced, and the bubbling properties of a system are strengthened; since the shapes of air bubbles affect the instantaneous rising velocity of the air bubbles, when the surface active substance is filled into the oil, the shapes of the air bubbles further can be effectively controlled, and the air bubbles are inhibited from being deformed; and a height-width ratio and the shapes of the air bubbles tend to be stable due to a proper amount of the surface active substance, so that the rising velocity of the air bubbles is reduced, thereby increasing the stabilization time of the air bubbles in the oil, and strengthening the gas-liquid mass transfer.
