METHOD AND DEVICE FOR OBTAINING ACETYLENE AND SYNTHESIS-GAS Russian patent published in 2016 - IPC B01J4/00 

FIELD: chemistry.

SUBSTANCE: subject of claimed invention is method for obtaining acetylene and synthesis-gas by partial oxidation of hydrocarbons with oxygen, with initial gases, composition of which includes hydrocarbon-containing flow and oxygen-containing flow, first being preliminarily heated separately, then being mixed in mixing zone, with initiation of their reaction in burning chamber after flowing through unit of burners, with the following fast cooling; method characterised by the fact that flow of washing gas is supplied on internal wall of combustion chamber, said flow of washing gas is introduced by some supplying pipelines, with said supplying pipelines being made inside combustion chamber in such a way that orientation of vector of main direction of emitted washing gas flow deviates by not more than 10° from orientation of vector of main direction of gas, supplied through unit of burners, and supplying pipelines are characterised by width of slot of output opening in 1/1000-3/100, preferably 1/500-1/100 of combustion chamber diameter, and if considered with respect to main direction of gas flow, realised is supplied through unit of burners, multi-stage supply of washing gas flow in points, located one after another, with free section of combustion chamber, accessible for flowing of gas flow, output from unit of burners at the level of supplying pipelines for washing gas flow, being approximately constant.

EFFECT: increase of method efficiency.
