The invention relates to a process for the preparation of acetylene and synthesis gas by thermal treatment of a starting mixture containing one or more hydrocarbons and in addition molecular oxygen and/or one or more compounds containing the element oxygen, in which the starting mixture is heated, brought to reaction in a reactor and subsequently cooled. The process has the special feature that the starting mixture is heated to a maximum of 1400&deg; C. It is then possible to carry out the process with comparatively little expenditure of energy.

Preparation of acetylene and synthesis gas

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.
