METHOD OF PRODUCING CATALYTIC CONVERTER BASED ON AlO FOR DEHYDROGENATION OF C-C HYDROCARBONS Russian patent published in 2024 - IPC B01D71/02 B01J21/12 B01J23/36 B01J21/14 B01J23/30 C07C5/333 

FIELD: chemistry.

SUBSTANCE: invention relates to production of catalytic converters for producing unsaturated olefin and diene hydrocarbons. Disclosed is a method of producing a catalytic converter based on Al₂O₃ for dehydrogenation of C₈-C₉ hydrocarbons, comprising preparing a mixture of powders, pressing the mixture into a workpiece, carrying out synthesis, characterized by that the initial components are taken in the following ratio, wt.%: α-Al₂O₃ - 71–85, MgO - 3–6, SiC - 6–12, SiO₂ - 3–6, Re₂O₇ - 1.5–2.5, WO₃ - 1.5–2.5, pressing the mixture is carried out at pressure of 25–70 MPa, and synthesis is carried out by sintering at a maximum temperature of 1200–1300 °C.

EFFECT: simplifying the process of creating a catalytic converter (obtaining a converter in one step) for dehydrogenating C₈-C₉ hydrocarbons, reducing carbonisability of converter to 0,5 % by weight.
