Description
Изобретение относитс к снособам пропитки пористых носителей каталитическими платиносодержащими соединени ми.This invention relates to methods for impregnating porous supports with catalytic platinum-containing compounds.
Недостатком известных способов пропитки пористых носителей платиновыми соединени ми дл каталитического риформинга бензинов при определенном значении рН раствора вл етс необходимость многократной пропитки и сушки носител дл получени нужной концентрации в нем платины.A disadvantage of the known methods of impregnating porous carriers with platinum compounds for the catalytic reforming of gasolines at a certain pH of the solution is the need to repeatedly impregnate and dry the carrier to obtain the desired concentration of platinum in it.
Описываемый способ пропитки носителей позвол ет достигнуть нужной концентрации платины при однократной пропитке и отличаетс от известных способов тем, что в пропитывающий раствор добавл ют соединени , образующие с платинохлористоводородной кислотой или с платиновыми сло ми устойчивые, хорошо растворимые в воде, комплексные соединени или соли.The described method of carrier impregnation allows to achieve the desired concentration of platinum in a single impregnation and differs from the known methods in that the impregnating solution is added to compounds that form with platinum hydrochloric acid or platinum layers stable, readily soluble in water, complex compounds or salts.
Дл таких добавок служат моно-, ди- и триэтаноламины, моно-, дии триэтиламины, а также моно-, ди- и триметиламины или их смеси.For such additives, mono-, di- and triethanolamines, mono-, dii triethylamines, as well as mono-, di- and trimethylamines or mixtures thereof are used.
Описываемый способ по сн етс следующими примерами.The described method is illustrated by the following examples.
Пример 1. Из активного глинозема с зернами диаметром 4 мм, способного поглотить 44% воды и дающего при прокаливании до 1200° остаток в 96%, необходимо приготовить катализатор, содержащий 0,5% Pt в расчете на AljOs.Example 1. Of active alumina with grains with a diameter of 4 mm, capable of absorbing 44% of water and giving a residue of 96% during calcination to 1200 °, it is necessary to prepare a catalyst containing 0.5% Pt per AljOs.
На 2700 г глинозема берут 542 см раствора нлатинохлористоводородной кислоты с 24 2 Pt в литре с добавкой 17 см триэтаноламина и с помощью индикаторной бумаги устанавливают значение рН равное 3,5. Раствор разбавл ют дистиллированной водой до объема 1,19 л, что соответствует способности глинозема поглощать влагу.On 2700 g of alumina, 542 cm of hydrochloric acid 24 24 Pt per liter with 17 cm of triethanolamine are added and the indicator paper is set to a pH of 3.5. The solution is diluted with distilled water to a volume of 1.19 L, which corresponds to the ability of alumina to absorb moisture.
Глинозем обрызгивают приготовленным раствором и затем его подвергают сушке в электрической печи при 110° в течение 12 час., а затем в течение 6 час. выдерживают при 500°.Alumina is sprayed with the prepared solution and then it is dried in an electric oven at 110 ° for 12 hours and then for 6 hours. maintained at 500 °.
Пример 2. Получение катализатора с содержанием 0,5% Pt в расчете на безводный носитель AbOa/SiOa, который содержит SiOj в количестве 4%, и сформованного в щарики диаметром 3-3,5 мм- Способность носител поглощать влагу - 56%. Его остаток по,сле прокаливани при 1200° 93%. Пропитка хлоридом платины при рН 4,5.Example 2. Preparation of a catalyst with a content of 0.5% Pt calculated on anhydrous carrier AbOa / SiOa, which contains 4% of SiOj, and molded into balls 3–3.5 mm in diameter — The carrier’s ability to absorb moisture is 56%. Its residue is after calcination at 1200 ° 93%. Impregnation with platinum chloride at pH 4.5.
