Abstract: The application relates to a process for the preparation of synthesis gases by partial autothermal oxidation of liquid fuels and/or solid fuels in the presence of oxygen or oxygen-containing gases with the addition of a temperature moderator such as steam and/or CO2, in an empty reactor space without baffles at temperatures of 1000 to 1500 DEG C at a pressure of 1 to 100 bar, the reactants fuel and oxygen-containing gas being fed separately to the reactor, characterised in that the steam or CO2 is fed in simultaneously with the feed of the fuel and, immediately before the orifice for the fuel, the steam is let down through one or more nozzles into the fuel stream, the let-down step being carried out with 30 to 250%, preferably 80 to 140%, of the critical pressure ratio. The application furthermore relates to an apparatus for carrying out the process.

Abstract: O.Z. 32,091 The invention relates to a process for rapidly letting-down the pressure in continuous high pressure polymerization systems for the polymerization of ethylene. In this process, the let-down hot reaction mixture is passed into an expansion vessel in such a way that the jet of let-down hot reaction mixture issuing from the let-down line is led into the partially water-filled expansion vessel at an angle of from 0 to 45.degree. to the water surface, so that the jet does not enter below the surface but must touch or strike it. The method described makes it possible to let the mixture down partially and thus to slow down the decomposition in the case of explosive decomposition reactions occurring in the polymerization system.
