摘要： The laughing-gas-containing gas (1) is diluted by means of a diluting gas (2). The diluting gas (2) is virtually free from water fractions in the dryer (3). After feed of the diluting gas (2) via the feed line (13), exhaust gas (8) from the catalytic decomposition (7) is added (4) to the laughing-gas-containing feed gas (12). After addition (4) of the exhaust gas (8) from the catalytic decomposition of laughing gas (7), the laughing-gas-containing feed gas (12) is compressed (5) and passed to the heat exchanger (6). In the heat exchanger (6) the laughing-gas-containing feed gas (12) is preheated by heat exchange with the exhaust gas (8). The exhaust gas (8) is cooled in the heat exchanger (6) in this process. The preheated laughing-gas-containing feed gas (12) is passed via a further optional heater (11) as a feed to the catalytic laughing gas decomposition (7). In order to avoid a concentration build-up, some of the exhaust gas (8) is passed out (9) of the process. The exhaust gas (8) is further cooled by a further optional heat exchanger (10). The additional cooling by means of the heat exchanger (10) ensures that subsequent appliances such as the compressor are protected against overheating. By means of the heat exchanger (10), the permissible temperature of that part of the exhaust gas (8) which is released (9) to the atmosphere can also be controlled here. For optimal control of the intake temperature of the laughing-gas-containing feed gas (12) into the catalytic decomposition (7), at least some of the laughing-gas-containing feed gas (12) can bypass the heat exchanger (6) using a bypass (14).

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.
