METHOD OF ACETYLENE AND GAS-SYNTHESIS PRODUCING Russian patent published in 1999 - IPC

FIELD: chemical technology. SUBSTANCE: invention describes two variants of the method. The first variant: method of acetylene and gas-synthesis producing by partial oxidation of hydrocarbons with oxygen characterizing in that gaseous reagents are heated preliminary separately, mixed in the mixing zone up to homogeneity, subjected for interaction after passing through the combustion chamber and cooled rapidly with an aqueous medium for an abrupt cooling after reaction termination. Method provides for recirculation of an aqueous medium for an abrupt cooling in the closed system. The second variant: method of acetylene and gas-synthesis producing involves preliminary separate heating gaseous reagents, their mixing in the mixing zone up to homogeneity and an interaction after passing through the combustion chamber followed by rapid cooling with an aqueous medium for an abrupt cooling after reaction termination. Ratio between gaseous reagents is taken so that acetylene and carbon black formed in reaction are obtained at weight ratio 50-500. Method provides an elimination of defects of the known methods using an abrupt cooling with water or oils. EFFECT: improved method of producing. 20 cl, 1 tbl, 7 ex
