Abstract
Аморфный микро/мезопористый алюмосиликатный гель с контролируемым размером пор, имеющий площадь поверхности по крайней мере 500 м/г, и с молярным отношением SiO: AlOпо крайней мере 30 : 1 получают, гидролизуя и заставляя тетраалкиламмоний гидроксид, триалкоксид алюминия и тетраалкилортосиликат образовывать гель путем обработки при атмосферном давлении, при температуре, равной или выше, чем температура кипения, любыми спиртами, которые образуются в виде побочного продукта в указанной реакции гидролиза, не удаляя указанные спирты, или, в основном, удаляя из реакционных сред, полученный таким образом гель сушат и прокаливают. Полученный таким образом гель является активным катализатором в реакциях превращения углеводородов, в частности, в способах изомеризации и олигомеризации легких олефинов, например в способах олигомеризации пропилена с получением полезных жидких углеводородов для формуляции бензина и топлива для реактивных двигателей.
