    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.

    Abstract: Process for carrying out a high temperature reaction comprises feeding educts to a reaction chamber through channels of a burner block. The high temperature reaction is carried out at temperatures of at least 1500[deg] C with a short dwell time in the reaction chamber and the reaction mixture is rapidly cooled in a quenching region. Process for carrying out a high temperature reaction comprises feeding educts to a reaction chamber (4) through channels (2) of a burner block (3). The high temperature reaction is carried out at temperatures of at least 1500degrees C with a short dwell time in the reaction chamber and the reaction mixture is rapidly cooled in a quenching region (5). Direct cooling to 650-1200degrees C is carried out in the quenching region by introducing a vaporizing quenching medium and indirect cooling is carried out in a heat exchanger. Independent claims are also included for: (1) Reactor for carrying out the process; and (2) Process for scaling up a reactor.
