METHOD OF PRODUCING SYNTHESIS GAS WITH HIGH-TEMPERATURE CATALYTIC OXIDATIVE CONVERSION OF METHANE Russian patent published in 2016 - IPC C01B3/40 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering, namely to high-temperature catalytic oxidative methods of converting methane to produce synthetic gas. Method consists in feeding into the reactor, which holds a catalyst filled with inert head, initial gas mixture containing a mixture of methane and oxygen. Process is carried out at the temperature of catalyst 761-966 °C, the catalyst used is a nickel foam type catalyst, namely nickel foam with PPI - number of pores per linear inch is above 80, nickel foam with nickel hydroxide applied on its surface using electrochemical method, followed by drying of the surface to obtain nickel hydroxide on its surface or with subsequent drying and heat treatment with formation of nickel oxide on its surface, or nickel foam with metal of VI groups of the periodic table of elements applied on its surface by electrochemical process followed by subsequent drying and thermal treatment of the surface. Thermal treatment of the surface is carried out in air at the temperature of 500-600 °C.

EFFECT: technical result consists in improvement of conversion of methane and selectivity of carbon oxide and hydrogen, simplification of technology of method implementation and reduction of costs for the process.
