DEVICE AND METHOD OF CONVERTING METHANE USING A SUPERSONIC FLOW REACTOR Russian patent published in 2022 - IPC B01J3/00 

FIELD: chemical or physical processes.

SUBSTANCE: invention relates to production of methane by pyrolysis. Device for producing acetylene from a stream of raw material containing methane, including: a supersonic reactor for receiving a methane feed stream and heating the methane feed stream to a pyrolysis temperature; supersonic reactor shell for determining the boundaries of the reactor chamber, wherein the reaction chamber operates at temperature of 1,200 °C to 4,000 °C; supersonic reactor combustion zone for combustion of fuel source to produce high-temperature carrier gas, passing through the reactor space at supersonic speeds to accelerate and heat the flow of methane feedstock to pyrolysis temperature; reactor shell, comprising an inner shell and an outer shell with one or more channels between the inner shell and the outer shell, wherein the inner shell is made of a material, having thermal conductivity from 300 to 450 W/(m·K) to remove heat from the reactor chamber and a melting point of 500 °C to 2,000 °C; wherein the material is at least copper and chromium, or copper, chromium and zinc, or copper, chromium and niobium, or copper and zirconium, or copper, silver and zirconium, or mixtures thereof; and coating containing metallic nickel, nickel alloy, chromium metal, chromium alloy, platinum metal, platinum alloy, palladium or palladium alloy or mixtures thereof, deposited on the inner surface of the inner layer of the reactor shell.

EFFECT: high efficiency of the process of pyrolysis of initial raw material of light alkanes.
