SAPO-11 molecular sieve samples differing in the acid properties, crystal morphology and size, and secondary pore structure characteristics were obtained by crystallization of reaction gels with the SiO2/Al2O3 molar ratios of 0.1 and 0.3, prepared using aluminum isopropoxide or boehmite as an aluminum source. Platinum (0.5 wt %) was deposited onto the molecular sieves prepared, and the catalytic properties of the resulting samples in n-hexadecane hydroisomerization were studied. The hydrocarbon conversion on these samples varies from 76.8 to 87.7 wt %, and the isoparaffin formation selectivity, from 76.7 to 91.2 wt %.

Кристаллизацией реакционных гелей с мольными соотношениями SiO2/Al2O3, равными 0.1 и 0.3, приготовленных с использованием в качестве источника алюминия изопропоксида или бёмита, получены образцы молекулярного сита SAPO-11, различающиеся кислотными свойствами, морфологией, размерами кристаллов, характеристиками вторичной пористой структуры. Каталитические свойства синтезированных образцов после нанесения на них 0.5 мас. % Pt изучены в реакции гидроизомеризации н -гексадекана. Установлено, что конверсия углеводорода на этих образцах изменяется от 76.8 до 87.7 мас %, а селективность образования изо -парафинов - от 76.7 до 91.2 мас %.
