Изобретение относитс к носител м .дл катализаторов .This invention relates to a carrier for catalysts.
Известный носитель, состо щий из каолина, глины и кварцевого песка, с удельной поверхностью 1 -10 , объемом пор 0,17- 0,50 , преобладающим радиусом порThe known carrier consisting of kaolin, clay and quartz sand, with a specific surface area of 1-10, a pore volume of 0.17-0.50, the prevailing radius of pores
оabout
больще 2000 А, механической прочностью на истирание (остаток) 25-30% не находит широкого применени . Цель изобретени - получение носител сmore than 2000 A, the mechanical abrasion resistance (residue) of 25-30% is not widely used. The purpose of the invention is to obtain a carrier with
преобладающим радиусом пор 100-1000 А - достигаетс тем, что в него дополнительно ввод т кремниевую кислоту при следующем соотнощении между компонентами (вес. %):the predominant pore radius of 100-1000 A is achieved by the addition of silicic acid to it at the following ratio between the components (wt.%):
Каолин20-40Kaolin 20-40
Глина20-30Clay20-30
Кварцевый песок15-29Quartz sand 15-29
Кремниева кислота10-40Silicon acid 10-40
Примеры 1-5. Смесь порощка тонкого помола (остаток на сите 0060 составл ет 3- 5 вес. % в расчете на сухие компоненты), содержащего каолин прос новский, глину дружковскую , кварцевый песок люберецкий и кислоту кремниевую водную (Si02-nH2O), затвор ют водой до пастообразной консистенции. Из пасты формуют цилиндрики диаметром 3- 4 и высотой 4-5 мм, которые сущат 4 часExamples 1-5. A fine grinding powder mixture (residue on a 0060 sieve is 3–5 wt.% Based on dry ingredients) containing prosinnian kaolin, Druzhkovsky clay, Lyubertsy quartz sand and silicic acid water (Si02-nH2O), is water-cooled to paste-like consistency. Cylinders with a diameter of 3-4 and a height of 4-5 mm, which exist for 4 hours, are formed from the paste.
при 200-250°С с последующим обжигом на воздухе в течение 15-20 мин при 1150°С.at 200-250 ° С with subsequent roasting in air for 15-20 minutes at 1150 ° С.
Состав исходных порошков п свойства полученных носителей приведены в таблице.The composition of the initial powders and the properties of the obtained carriers are given in the table.
Таким образом, измен количество вводимой кремниевой кислоты, получают механически прочные (механическа прочность на истирание 97-90%) и термостойкие носители с удельной поверхностью 5,5-61 , радиусомThus, by changing the amount of injected silicic acid, mechanically strong (mechanical abrasion resistance of 97-90%) and heat-resistant carriers with a specific surface area of 5.5-61, with a radius of
пор 100-1000 А н объемом пор 0,25-0,52 . Остато на сите 0,60 составл ет 3-then 100-1000 And n pore volume of 0.25-0.52. The residue on the 0.60 mesh is 3-
