Abstract: PROBLEM TO BE SOLVED: To provide a burner block capable of performing a low temperature method for producing an acetylene-synthesis gas mixture and avoiding the existence of these ignitable mixtures in this low temperature method. SOLUTION: By a burner block (1) having a mouthpiece (2), a plurality of hydrocarbon passages (3) for the passage of a hydrocarbon-oxygen mixture used as a reacting material and at least one oxygen passage (4) for the passage of air or an air-oxygen mixture, an achievement is made. An ignition burner (5) can exist, and the combustion of the hydrocarbon for producing acetylene at the temperature under 1400 deg.C is permitted by the burner block.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing acetylene and synthesis gas, capable of obtaining the products with comparatively low consumption of energy. SOLUTION: This method for producing acetylene and synthesis gas comprises thermally treating a starting mixture containing one or more hydrocarbons and further molecular oxygen and/or one or more oxygen element-containing compounds, wherein the starting compounds are heated, reacted in a reactor and subsequently cooled, and the starting mixture is heated up to at most 1400 deg.C.

Abstract: Disclosed is a method for processing naphtha, according to which a) naphtha or a stream generated from naphtha in a preprocessing step is divided into a stream A that is stripped of aromatics and a stream B which is enriched with aromatics in a membrane unit, the aromatics concentration in stream A ranging from 2 to 12 percent by weight (step a); b) partial stream A is directed at least in part into a steam cracker (step b); c) partial stream B is directed at least in part into a unit in which said stream B is divided into a stream C or several streams C' C'', C''',..., which has/have a lower aromatics content than stream B, and a stream D or several streams D', D'', D''',..., which has/have a higher aromatics content than stream B, by means of a thermal process (step c); d) stream C or at least one of the streams C', C'', C''' is delivered as a whole or in part to the feed for the steam cracker or directly to the steam cracker (step d).

Abstract: Process for the work-up of naphtha, wherein a) naphtha or a stream produced from naphtha in a pretreatment step is separated in a membrane unit into a stream A which is depleted in aromatics and a stream B which is enriched in aromatics, with the aromatics concentration in stream A being from 2 to 12% by weight (step a), b) at least part of the substream A is fed to a steam cracker (step b), c) at least part of the substream B is fed to a unit in which it is separated by means of a thermal process into a stream C which has a lower aromatics content than stream B or a plurality of streams C', C'', C''' . . . which each have lower aromatics contents than stream B and a stream D which has a higher aromatics content than stream B or a plurality of streams D', D'', D''' . . . which each have higher aromatics contents than stream B (step c), and d) the stream C or at least one of the streams C', C'', C''', in each case in part or in its entirety, is added to the feed to the steam cracker or fed into the steam cracker itself (step d).
