Abstract
Description
Изобретение относится к способам получения высококремнеземного цеолита типа ZSM-5, применяемого в качестве компонента катализаторов и сорбентов в нефтеперерабатывающей и нефтехимической промышленности. The invention relates to methods for producing high-silica zeolite type ZSM-5, used as a component of catalysts and sorbents in the oil refining and petrochemical industries.
Целью изобретения является повышение степени кристалличности продукта. The aim of the invention is to increase the degree of crystallinity of the product.
П р и м е р. Готовят реакционную смесь со следующим мольным соотношением ингpедиентов: Na2O 50 МЭА 53 C8H3O Al2O3 50 SiO2 535 H2O, где МЭА моноэтаноламин, для чего к 254 мл дистиллированной воды приливают 6,31 мл раствора алюмината натрия (Na2O 272,8 г/л, Al2O3 260 г/л, S 1,45, вносят 0,82 г гидроокиси алюминия (98%) и 90,33 г молотого силикагеля (содержание Al2O3 0,8 мас.), после чего, не прекращая перемешивания, приливают 85,58 г МЭА (99%-ного) и 12,97 г глицерина (98,5%-ного). Полученную реакционную смесь гомогенизируют перемешиванием в течение 0,5 ч при комнатной температуре (мольное отношение глицерина и воды равно 0,01), после чего загружают в автоклав и кристаллизуют в статических условиях при 150оС 150 ч. После окончания кристаллизации при этой температуре смесь подвергают охлаждению в автоклавe до 50оС со скоростью 7оС/ч. Продукт отфильтровывают, промывают дистиллированной водой до рН 7-8 и сушат при 120оС 10 ч. Получают цеолит типа ZSM-5.PRI me R. A reaction mixture is prepared with the following molar ratio of ingredients: Na 2 O 50 MEA 53 C 8 H 3 O Al 2 O 3 50 SiO 2 535 H 2 O, where MEA is monoethanolamine, for which 6.31 ml of aluminate solution is added to 254 ml of distilled water sodium (Na 2 O 272.8 g / l, Al 2 O 3 260 g / l, S 1.45, contribute 0.82 g of aluminum hydroxide (98%) and 90.33 g of ground silica gel (Al 2 O 3 content 0.8 wt.), After which 85.58 g of MEA (99%) and 12.97 g of glycerol (98.5%) were added without stopping stirring, and the resulting reaction mixture was homogenized by stirring for 0, 5 h at room temperature (molar ratio of glyc Erin and water equal to 0.01), and then charged into the autoclave and crystallized under static conditions at 150
Образцы полученных цеолитов подвергают рентгенофазовому анализу (ДРОН-3) с целью определения степени кристалличности, химанализу и определению адсорбционной емкости по парам н-гептана и бензола при Р/Рs 0,4.Samples of the obtained zeolites are subjected to x-ray phase analysis (DRON-3) in order to determine the degree of crystallinity, chemical analysis and determination of the adsorption capacity for pairs of n-heptane and benzene at P / P s 0.4.
Результаты остальных опытов и данные прототипа представлены в таблице. The results of the remaining experiments and the data of the prototype are presented in the table.
Таким образом, предложенный способ позволяет повысить степень кристалличности продукта. Thus, the proposed method allows to increase the degree of crystallinity of the product.
