摘要： The invention relates to a process for preparing linear α-olefins, wherein ethylene 1a is conducted into the oligomerization reactor 2 in the liquid phase. The oligomerization reactor 2 has a mechanical stirrer 2a in order to ensure optimal mixing of the liquid ethylene and of the catalyst in the liquid phase. From the top of the oligomerization reactor 2, vaporized ethylene is drawn off together with light α-olefins and a small proportion of the organic solvent. The gas mixture drawn off from the top of the reactor 2 is condensed together with gaseous fresh ethylene 7 by means of heat exchanger 3 and separator 4. The liquid phase drawn off from the separator 4 is conducted by means of circulation pump 5a as liquid ethylene input 1a back into the oligomerization reactor 2. The liquid products of the oligomerization reaction are drawn off 8 laterally from the base of the reactor 2.

摘要： A process for removing impurities, in particular oxides of sulphur (SOx) and/or oxides of nitrogen (NOx) from oxygen-containing gas streams by scrubbing with at least one washing agent is described. In order to achieve effective gas purification in an economical manner even in the case of so-called large “oxyfuel” furnaces which operate with oxygen as fuel gas, it is proposed to convert the impurities at an elevated pressure of at least 2 bar with at least one basic constituent of the washing agent into salts and to wash out said impurities as dissolved salts.
