Изобретение относитс к способам приготовлени катализаторов крекинга углеводородов .This invention relates to methods for preparing hydrocarbon cracking catalysts.
Известен способ приготовлени катализатора крекинга углеводородов путем обработки алюмосиликатного катализатора крекинга водным раствором NaCl до содержани его 0,05-0,15 вес. %.A known method of preparing a catalyst for cracking hydrocarbons by treating an aluminosilicate cracking catalyst with an aqueous solution of NaCl to a content of 0.05-0.15 weight. %
Недостатком указанного способа вл етс его относительно низка крекирующа активность .The disadvantage of this method is its relatively low cracking activity.
С целью повышени крекирующей активности катализатора, в качестве нромотора используют азотнокислый кальций в количестве 0,05-0,15 вес. %. При этом крекирующа активность катализатора возрастает в среднем на 35%.In order to increase the cracking activity of the catalyst, calcium nitrate in the amount of 0.05-0.15 weight is used as the nromotor. % At the same time, the cracking activity of the catalyst increases on average by 35%.
Пример. На часть свежего образца алюмосиликатного катализатора, содержащего 10% АЬОз, нанос т методом пропитки из раствора петролейного эфира 10 вес. % хинолина . После удалени петролейного эфнра на катализатор методом однократной нропиткц водным раствором нанос т 0,05-0.15 вес. % азотнокислого кальци . Затем катализатор сушат и прокаливают в муфельной нечп при 550-600°С. Хино.шн удал ют в процессе прокалки за счет десорбции и за счет окислени кислородом воздуха.Example. A portion of a fresh sample of an aluminosilicate catalyst containing 10% AO3 is applied by impregnation from a solution of petroleum ether to 10 wt. % quinoline. After removing petroleum refinery, 0.05-0.15 weight is applied to the catalyst using a single impregnation method with an aqueous solution. % calcium nitrate. Then the catalyst is dried and calcined in a muffle chamber at 550-600 ° C. The hino.shn is removed during the calcination process due to desorption and oxidation by atmospheric oxygen.
На другую часть образца алюлюсиликатного катализатора нанос т 0,05-0,15 вес. % азотнокислого кальци путем цропитки водным раствором той же соли.0.05-0.15 weight is applied to another part of the sample of the aluminosilicate catalyst. % calcium nitrate by impregnation with an aqueous solution of the same salt.
Операцпю сушки и нрокалки провод т в тех же услови х. Перед проппткой раствором Са()2 на катализатор хинолин не нанос т. Данные по промотированию алюмосиликатi;oro катализатора с азотнокислым кальциемDrying and nanocale are carried out under the same conditions. Before propping, a solution of Ca () 2 is not applied to the quinoline catalyst. Data on the promotion of aluminosilicate; oro catalyst with calcium nitrate
приведены ц таблице.are shown in the table.
Из таблицы видно, что активность катализатора , промотированного азотнокислым кальцием увеличиваетс с 44% до 71,5 вес. % илиThe table shows that the activity of the catalyst promoted with calcium nitrate increases from 44% to 71.5 wt. % or
Предмет изобретени Subject invention
Способ приготовлени алюмосиликатного катализатора крекинга углеводородов путем обработки алюмосиликатного катализатора крекинга водным раствором промотора, отна 60 отн. % по сравнению с исходным катализатором и пор дка 35 отн. % с образцом, промотироваииым хлористым натрием.A method for preparing an aluminosilicate catalyst for cracking hydrocarbons by treating an aluminosilicate cracking catalyst with an aqueous solution of a promoter, 60 rel. % compared to the original catalyst and in the order of 35 rel. % with sample, promoted with sodium chloride.
личающийс тем, что, с целью повышени крекирующей активности катализатора, в качестве промотора используют азотнокислый кальций в количестве 0,05-0,15 вес. %.characterized in that, in order to increase the cracking activity of the catalyst, calcium nitrate in an amount of 0.05-0.15 weight is used as a promoter. %
