Abstract: The invention relates to a process for the scale-up of a reactor (1) having a supply of a reaction mixture via channels (2) of a burner block (3) to a reaction chamber (4), a high temperature reaction having a short residence time taking place in the reaction chamber (4) and the reaction mixture subsequently being rapidly cooled in a quench area (5). For a throughput enlargement the internal diameter of the reactor (1) is enlarged, the transition of the reaction chamber (4) to the quench area (5) being designed in the form of a gap, which is restricted to a width in the range from 2 to 200 mm.

Abstract: The invention relates to a process for carrying out a high-temperature reaction, in which starting materials are supplied to a reaction chamber (4) through channels (2) of a burner block (3), where in the reaction chamber (4) the high-temperature reaction having a short residence time takes place at a temperature of at least 1500° C. and the reaction mixture is subsequently rapidly cooled in a quench area (5). The cooling takes place first as a direct cooling to a temperature in the range from 650° C. to 1200° C. by supply of an evaporating quench medium and subsequently as an indirect cooling in a heat exchanger.

Abstract: A method and apparatus for generating acetylene gas by reacting water and calcium carbide wherein a tank containing water is pressurized by a pump in a manner feeding the water to another vessel wherein it reacts with particulate calcium carbide to generate acetylene gas. A portion of the acetylene gas is returned through a pressure regulator to the water tank in a manner maintaining regulated system operating pressure on the water to sustain the reaction without overproduction of the gas. The apparatus can be located in a vehicle for on board generation of acetylene gas as fuel for the internal combustion engine thereof.
