A process for the preparation of acetylene and synthesis gas by partial thermal oxidation in a reactor which has a burner having passages, wherein the starting materials to be reacted are rapidly and completely mixed only immediately before the flame reaction zone in the passages of the burner, a mean flow rate which exceeds the flame propagation velocities under the given reaction conditions being established in the mixing zone within the passages.

Method and device for producing acetylene and synthesis gas by rapidly mixing the reactants

The invention relates to a process for the scale-up of a reactor () having a supply of a reaction mixture via channels () of a burner block () to a reaction chamber (), a high temperature reaction having a short residence time taking place in the reaction chamber () and the reaction mixture subsequently being rapidly cooled in a quench area (). For a throughput enlargement the internal diameter of the reactor () is enlarged, the transition of the reaction chamber () to the quench area () being designed in the form of a gap, which is restricted to a width in the range from 2 to 200 mm.

Process for the scale-up of a reactor for carrying out a high-temperature reaction, reactor and use

The invention relates to a reactor () having a supply of a reaction mixture via channels () of a burner block () in a reaction chamber (), a high temperature reaction having a short residence time taking place in the reaction chamber () and the reaction mixture then being rapidly cooled in a quench area (). In the reactor (), all surfaces delineating the reaction chamber () are formed from a fire-resistant ceramic having an alumina content of at least 80% by weight, which is stable at reaction temperature.

Reactor for high-temperature reactions and use

The present invention relates to a process for the continuous preparation of methoxyamine hydrochloride by cleavage of acetone oxime methyl ether by means of hydrogen chloride and water, wherein the cleavage is carried out in a reaction column having less than 20 theoretical plates and the amount taken off at the top is set to at least 30% of the amount of feed.

Method for the continuous production of methoxyamine hydrochloride

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.
