Description
Увеличение активности алюмосиликатных катализаторов крекинга имеет большое промышленное значение, так как каталитический крекинг вл етс са.мым многотоннажным каталитическим процессом.The increase in the activity of aluminosilicate cracking catalysts is of great industrial importance, since catalytic cracking is a very large catalytic process.
В литературе в последние годы (1959, 1961) по вились указани о модифицировании алюмосиликатных катализаторов путем предварительного облучени их нейтронами, электронами и улучами.In the literature in recent years (1959, 1961), there have been indications of the modification of aluminosilicate catalysts by pre-irradiating them with neutrons, electrons, and upgrades.
По предлагаемому способу облучение алюмосиликатных катализаторов производ т Y-лучами Со или протонами.According to the proposed method, the irradiation of aluminosilicate catalysts is carried out with Y rays of Co or protons.
При облучении алюмосиликатного катализатора, содержаш,его 12,8 вес % и 87,1 вес. % SiO2 -лучами , активность катализатора по крекингу кумола при 400° возрастает по сравнению с необлученным катализатором на 80-110%, а при облучении протонами на 25-30%.Upon irradiation of the aluminosilicate catalyst, it contains 12.8 wt% and 87.1 wt. % SiO2 -radiation, the activity of the catalyst for the cracking of cumene at 400 ° increases compared with the non-irradiated catalyst by 80-110%, and when irradiated with protons by 25-30%.
Облучение у-лучами производ т на кобальтовой установке К-18000 с помощью ускорител протонов ЭГ-2,5.Irradiation with y-rays was carried out on a cobalt K-18000 installation using an EG-2.5 proton accelerator.
Дл облучени протонами слой алюмосиликатного катализатора помещают в кювету, из которой выкачивают воздух и охлаждают жидки.м азотом. Катализатор облучают в течение 1 час; энерги протонов равна 1,5 мэв, интенсивность пучка протонов 20 мка.For proton irradiation, a layer of aluminosilicate catalyst is placed in a cuvette, from which air is pumped out and cooled with liquid nitrogen. The catalyst is irradiated for 1 hour; proton energy is 1.5 meV, proton beam intensity is 20 μA.
Дл облучени уЛучами ката тизатор помещают в стекл нную ампулу .For irradiation with cells, the catalyst is placed in a glass ampoule.
Доза облучени равна 48 млн. рентген (по ферросульфатному методу ) .The radiation dose is 48 million X-rays (by the ferrosulfate method).
Активность полученных катализаторов провер ют при крекинге очищенного от гидроперекиси изопропилбензола (кумола); крекинг провод т при температуре 400° в проточном реакторе при различных скорост х подачи кумола. Об активности катализатора суд т по степени превращени кумола.The activity of the resulting catalysts was tested during the cracking of isopropylbenzene (cumene) hydroperoxide purified; the cracking is carried out at a temperature of 400 ° in a flow reactor at different cumene feed rates. The activity of the catalyst is judged by the degree of cumene conversion.
Результаты испытаний видны из таблицы.The test results are visible from the table.
Таким образом, в указанных услови х облучени и пределах скорости подачи изопропилбензола степень превращени изопропилбензола при применении катализатора, облученного у-лучамн , возрастает на 80-ПО вес. %, а облученного протонами - ка 25-35 вес. %.Thus, under the specified irradiation conditions and the limits of the feed rate of isopropylbenzene, the degree of conversion of isopropylbenzene when using a catalyst irradiated with γ-rays increases by 80% by weight. %, and irradiated with protons - ka 25-35 weight. %
