Claims (7)
1. Способ каталитической изомеризации C8-ароматических соединений, а именно, неравновесной смеси сырья из ксилолов и этилбензола, включающий контактирование смеси сырья в присутствии водорода в зоне изомеризации с каталитической системой, содержащей молекулярное сито, отличающийся тем, что используют каталитическую систему, содержащую эффективное количество кристаллического силикоалюмофосфатного молекулярного сита СМ-3, и осуществляют процесс в условиях изомеризации C8-ароматических соединений, эффективных для получения изомеризованного продукта, содержащего п-ксилол в более высоком количественном отношении, чем в сырьевой смеси.
2. Способ по п.1, отличающийся тем, что каталитическая система содержит эффективное количество компонента из металла платиновой группы.
3. Способ по п.1 или 2, отличающийся тем, что каталитическая система, кроме того, включает связывающее вещество из неорганического оксида, содержащее оксид алюминия и оксид кремния или их смесь.
4. Способ по п.2, отличающийся тем, что эффективное количество компонента из металла платиновой группы составляет от 0,1 до 5 мас.% платины при расчете на основе элемента.
5. Способ по любому из пп.1 - 4, отличающийся тем, что изомеризованный продукт содержит более, чем равновес- ную концентрацию пара-ксилола.
6. Способ по одному из пп.1 - 5, отличающийся тем, что каталитическая система содержит от 0,1 до 5 мас.% при расчете на основе элемента платинового компонента; от 10 до 100 мас.% кристаллического силикоалюмофосфатного молекулярного сита СМ-3 и связывающего вещества из неорганического оксида.
7. Способ по одному из пп.1 - 6, отличающийся тем, что изомеризацию C8-ароматических соединений осуществляют при температуре от 300o до 500oC, давлении от 101,3 до 5065 кПа (1 - 50 атм), объемной скорости от 0,5 до 10•ч-1 и мольном отношении водорода к углеводородам, равном от 0,5 : 1 до 25 : 1.
