AB - <p class="a">Using the experimental and numerical methods, the kinetics of deep methane oxidation on a fiber-like oxide catalyst with honeycomb structure is studied. ALSIFLEX-KT1600 fibers are used as a carrier, and spinel (% of mass) is used as a catalytic contact: MgAl<sub>2</sub>O<sub>4</sub> – 22.07 %; NiO – 2.02 %; Cr<sub>2</sub>O<sub>3</sub> – 3.49 %. Si+SiO2 adhesive – 18.97 % and organic glue – 1.72 are used to impart a stable honeycomb structure.</p><p class="a">To complete the numerical analysis of kinetic data, a complete two-phase mathematical model is developed. The microchannel model is adopted as a basis. This model is characterized by the equality of the total area of the cross-sections of the microchannels and the area of the free section of the catalyst, and the total surface area of heat and mass transfer is equal to the specific surface area of the catalyst.</p><p class="a">As a result of the work, the values of similarity, mass and heat transfer coefficients, the effective working surface of the catalyst, participating in the heterogeneously catalytic reaction of complete oxidation of methane S<sub>w</sub> = 7640±150 m²/m³ are calculated.</p>The experimental kinetic data of methane oxidation on the catalyst have been confirmed by mathematical calculations, a refined microkinetic equation has been derived, the flow areas of the process have been established, and the performance of the synthesized catalyst has been established
