METHOD AND DEVICE FOR PRODUCING ACETYLENE AND SYNTHESIS GAS Russian patent published in 2016 - IPC C01B3/36 C07C2/78 B01J4/00 F23D14/62 

FIELD: chemistry.

SUBSTANCE: invention relates to improved method of producing acetylene and synthetic gas. Disclosed is method of producing acetylene and synthetic gas by partial oxidation of hydrocarbons with oxygen, wherein initial gases, which enter stream containing hydrocarbon, and flow containing oxygen, first, preliminary heated separately, then mixed in mixing zone, and after flowing via burners cause their reaction in combustion chamber, then quickly cooled. At that, to block of burners surface facing combustion chamber stream of washing gas flow is added. this washing gas is introduced via several holes through burner unit, wherein averaged ratio of effective area of unit of burners surface to number of these holes for gas flushing flow in burners ranges from 5 to 100 cm², wherein averaged ratio of unit of burners effective surface to number of these holes for gas flushing flow in burners is calculated from ratio of total effective surface of unit of burners to total number of holes for gas flushing and carried out through holes for washing flow to gas distributing devices so that 70-100 vol% of supplied washing gas flow is directed parallel to surface of burners unit side facing combustion chamber.

EFFECT: invention allows to produce synthesis gas and acetylene using improved method of partial oxidation of hydrocarbons, which prevents deposits on surface of unit of burners without using mechanical treatment.
