METHOD OF PRODUCING A CATALYST FOR OXIDISING METHANOL TO FORMALDEHYDE Russian patent published in 2019 - IPC B01J23/881 B01J21/16 B01J21/04 B01J37/04 B01J35/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a catalyst for oxidising methanol to formaldehyde and can be used in producing formaldehyde. Method of obtaining a catalyst for oxidising methanol to formaldehyde, containing mixture consisting of Fe₂(MoO₄)₃/MoO₃ at atomic ratio Mo/Fe = 2.5 and clay or boehmite in amount of up to 15 wt%, includes stages of catalyst grains molding and their subsequent thermal treatment. According to invention to Fe₂(MoO₄)₃/MoO₃ dry clay and / or boehmite is added; water is added to the obtained mixture to obtain a molding paste with moisture content of 10–20 %; the catalyst grains are molded by extrusion.

EFFECT: low complexity of the technology of producing catalysts, enabling production of catalysts with high strength properties and broader functional capabilities.
