Abstract

A method for producing a block vanadium catalyst for the oxidation of sulfur dioxide has been studied, which includes the stage of preparing a honeycomb structure framework based on silica raw materials 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 the channels. Data on the structural and mechanical properties of the honeycomb catalyst paste have been obtained. A mode of heat treatment of molded products with the production of mechanically strong blocks as carriers of the vanadium catalyst is proposed. Information about the performance of a block vanadium catalyst in comparison with an industrial catalyst of a granular form is given. Ill. 4. Ref. 14. Tab. 1.
