Abstract

The invention relates to a process for the production of acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, wherein the gaseous reactants are separately preheated, intimately mixed in a mixing zone, reacted after passing a burner block and rapidly quenched with an aqueous quench medium after reaction, further characterized in that the aqueous quench medium is recirculated in a closed system. Preferably the ratio of the gaseous reactants is selected in such a way that acetylene and soot produced in the reaction are obtained in a weight ratio of 50 to 500.
