Abstract

The invention discloses a magnetic response nanorod-shaped desulfurization adsorbent which has a stirring function under the action of a magnetic field and can improve mass transfer rates in macroscopic and microscopic solid-liquid / liquid-liquid / gas-liquid systems. The magnetic response nanorod-like desulfurization adsorbent is composed of a magnetic nanorod and a coated porous shell layer, the length range of the magnetic nanorod is 1-30 [mu] m, the magnetic saturation susceptibility is 1000-15000 Oe, and the thickness range of the coated porous shell layer is 50-300 nm.

Description

technical field [0001] The present invention relates to an adsorbent, a preparation method and application thereof, and more particularly to a magnetically responsive nanorod-shaped desulfurization adsorbent, preparation method and application thereof. Background technique [0002] The mass transfer rate is extremely important for the adsorption and catalytic process, so a good adsorption rate is the premise to ensure the adsorption separation efficiency and the effect of heterogeneous catalytic reaction. In the traditional adsorption process, mechanical stirring or magnetic stirring is the most common means to increase the mass transfer rate. Therefore, a stirring paddle or a stirring bar is required in the liquid phase adsorption separation process, and the adsorbent itself does not have the controllable ability to Improve mass transfer. In addition, in vessels such as microchannels, the limitation of stirrer bar size renders the application of mechanical or magnetic stir...
