METHOD OF PRODUCING SYNTHESIS GAS Russian patent published in 2015 - IPC C01B3/28 B01J38/04 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the field of petrochemistry and more specifically to a method of producing synthesis gas which is used as the feedstock, for example, for the synthesis of methanol, dimethyl ether, hydrocarbons by Fischer-Tropsch method. The method of producing synthesis gas comprises oxidative conversion of methane-containing gas at a temperature more than 650°C in through-flow riser, using as oxidant the microspherical or crushed catalyst based on metal oxides, capable of multiple redox transitions, at that the catalyst is continuously passed through the riser upwards in the methane-containing gas flow with a residence time of the feedstock in the reaction zone of 0.1-10 s, separating the catalyst passing from the reactor from the product and regeneration of the catalyst by oxidation with carbon dioxide in the regenerator from which the regenerated catalyst enters the reactor. The oxidative conversion of methane-containing feedstock and regeneration of regenerated catalyst is carried out simultaneously and continuously.

EFFECT: invention enables to improve the removal rate of the product, to reduce energy consumptions for transportation of oxygen-containing agent, to reduce the risk of explosion and ignition, as well as to adjust the composition of the synthesis gas.
