Formation and Properties of Block Vanadium Catalyst from Nanomaterial Based Upon SiO2 for SO2 Oxidation.

A method for producing block vanadium catalyst for oxidation of sulfur dioxide is studied, which includes a stage of preparing a honeycomb structure framework based upon silica raw material in the form of white soot, followed by applying a substrate in the form of amorphous silicon dioxide and an active component to the surface of channels. Data for structural and mechanical properties of the honeycomb catalyst paste are obtained. Aheat treatment regime for molded products with production of mechanically strong blocks as carriers of vanadium catalyst is proposed. Information about the performance of a block vanadium catalyst compared with an industrial catalyst of a granular form is provided. [ABSTRACT FROM AUTHOR]
