Description

. 1. one

Изобретение относитс  к области очистки углеводородных газов от ацетилена и его гомологов.The invention relates to the field of purification of hydrocarbon gases from acetylene and its homologues.

Известен способ очистки углеводородных газов от указаииых примесей путем гидрировани  их водородом в ирисутствии известных катализаторов гидрировани , например платиновых и палладиевых. Однако при осуществлении этого способа за счет теплоты реакции гидрировани  температура в конце процесса гидрировани  может повышатьс  до 100°С, что приводит к резкому снижению селективности процесса и потер м содержащихс  в газе этилена и нронилена.A known method of purifying hydrocarbon gases from indicated impurities by hydrogenating them with hydrogen in the presence of known hydrogenation catalysts, such as platinum and palladium. However, when carrying out this process due to the heat of hydrogenation reaction, the temperature at the end of the hydrogenation process can rise to 100 ° C, which leads to a sharp decrease in the selectivity of the process and loss of ethylene and nronylene contained in the gas.

Предлагают процесс гидрировани  осуществл ть в присутствии аммиака.The hydrogenation process is proposed to be carried out in the presence of ammonia.

Пример 1. При пронускании газов пиролиза , содержащих до 0,8% ацетиленовых углеводородов , 15-20,0% водорода, 28-30,0% этилена, над палладиевым катализатором температурный интервал селективной работы катализатора равен 25°С при добавке 0,03 вес. % аммиака температурный интервал селективной работы превышает 50°С.Example 1. With the penetration of pyrolysis gases containing up to 0.8% of acetylene hydrocarbons, 15-20.0% of hydrogen, 28-30.0% of ethylene, over a palladium catalyst, the temperature interval of the selective operation of the catalyst is 25 ° C with the addition of 0.03 weight. % ammonia temperature range of selective operation exceeds 50 ° C.

Пример 2. В газах высокотемпературного пиролиза этана содержитс , об. %: Н 33,0-40,0; С2П4 30,0-35,0; СзНе 0,7-1,5 суммы ацетиленовых углеводородов до 1,Оч./1 млн.Example 2. In the gases of high-temperature pyrolysis, ethane contains, vol. %: H 33.0-40.0; S2P4 30.0-35.0; SzNe 0.7-1.5 amounts of acetylene hydrocarbons to 1, O./1 million

Дл  очистки от иримесей ацетиленовых углеводородов пирогаз нагревают до 50°С и иропускают над катализатором гидрировани . За счет теплоты, выдел ющейс  при реакции гидрировани , температура иа выходе из реактора достигает вьпие 100°С и селективность работы катализаторов понижаетс . В газе, отход щем из реактора, содержитс  об. %: HZ 25; С2Н4 25; СзНц 0,5 ацетиленовых углеводородов менее 10 ч./ млн.For purification of acetylene hydrocarbons from irimeses, pyrogas is heated to 50 ° C and spun over a hydrogenation catalyst. Due to the heat generated by the hydrogenation reaction, the temperature at the reactor outlet reaches 100 ° C and the selectivity of the catalysts decreases. Gas from the reactor contains vol. %: HZ 25; C2H4 25; SzNts 0.5 acetylene hydrocarbons less than 10 hours / million

При добавке к исходному газу указа)1)1ог() выше состава менее 1% ЫПц иодьем температуры выше 100°С ие нриводит к потере селективности процесса каталитической очистки. В отход игем газе после реактора содержитс , об. %: 33,0-40,0; 30,0-35,0; СзН, 0,7-1,5 ацетиленовых углеводородов менее 10 ч. /1 млн.When an edict is added to the source gas, 1) 1 () above the composition is less than 1% LiP and a temperature above 100 ° C and leads to a loss of the selectivity of the catalytic purification process. The waste gas after the reactor is contained in vol. %: 33.0-40.0; 30.0-35.0; SzN, 0.7-1.5 acetylene hydrocarbons less than 10 hours / 1 million
