CATALYST FOR DEHYDRATION OF C-C HYDROCARBON MIXTURE TO OLEFINS AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2022 - IPC B01J23/28 B01J27/22 B01J32/00 B01J37/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst for dehydration of a C₁-C₄ hydrocarbon mixture to olefins, containing a molybdenum compound and a carrier. The catalyst is characterised by containing, as a molybdenum compound, a nanostructured coating of molybdenum oxycarbide with a thickness of 5 to 50 nm, and containing, as a carrier, multi-walled carbon nanotubes with an average outer diameter of 70 nm, a length of 1 to 500 mcm, a specific surface of 38±2.2 m²/g, and a bulk density of 0.1 to 0.2 g∙cm^-3. The invention also relates to a method for producing the catalyst.

EFFECT: provided are one-stage process for producing a catalyst, improved environmental friendliness of the process, increased total yield of olefins such as ethylene and propylene, absence of coke formation.
