Abstract

The present invention proposes a multi-element composite adsorption material for removing vanadium, by combining CuO-SnO 2 ‑La 2 o 3 The composite oxide was supported on activated carbon, and an adsorbent material capable of effectively removing vanadium was developed, which has the advantages of large adsorption capacity and low regeneration energy consumption.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a multi-element composite adsorption material for removing vanadium and its preparation method and application. Background technique [0002] In modern industrial production, vanadium is generally contained in the fossil fuels used. For example, hard coal around the world contains about 19ppm of vanadium (126ppm in ash), about 10ppm in lignite (63ppm in ash), and the vanadium content in petroleum can be as high as 36- 114ppm. The vanadium emitted to the atmosphere during the burning of fossil fuels, if the world consumes 2 billion tons of oil every year, assuming that half of the vanadium in the oil enters the atmosphere, this alone will reach 20,000 tons, so the vanadium in the atmosphere mainly comes from oil combustion . Moreover, vanadium in the atmosphere has a strong catalytic effect on SO 2 to SO 3 The ability to transform is one of the key substances in t...
