Abstract

The invention provides a device for enhancing gas-liquid mass transfer in a bubbling bed hydrogenation reactor, comprising a main pipe and a filling pipe connected to the main pipe, the main pipe contains oil, and the filling pipe The injection tube is used to add surfactant to the oil in the main tube. The present invention can significantly reduce the surface tension between the two-phase interface and enhance the foaming performance of the system by adding surface-active substances to the oil; since the shape of the bubbles affects the instantaneous speed of the bubbles rising, adding surface-active substances to the oil Substances can also effectively regulate the shape of the bubbles and inhibit the deformation of the bubbles. An appropriate amount of surface active substances can stabilize the aspect ratio and shape of the bubbles and reduce the rising speed of the bubbles, thereby increasing the stable time of the bubbles in the oil and strengthening gas-liquid mass transfer.

Description

technical field [0001] The invention relates to the technical field of gas-liquid mass transfer, in particular to a device for strengthening gas-liquid mass transfer in a bubbling bed hydrogenation reactor. Background technique [0002] As one of the most effective ways to lighten heavy oil, hydrocracking is widely used in improving the utilization rate of oil products and upgrading the quality of oil products. Usually, different reactor types and hydrogenation processes are selected according to the differences in the hydrodynamic properties of different reaction materials. At present, the most widely used are fixed bed hydrogenation reactor, moving bed hydrogenation reactor, bubbling bed (suspended bed and ebullating bed) hydrogenation reactor, etc. Among them, the fluidized bed has become one of the important means of lightening heavy oil due to its wide adaptability of raw materials and flexible operation. Since 2000, more fluidized bed residue hydrocracking units have...
