Claims (8)
1. Способ адсорбционного разделения с использованием моделированного подвижного слоя для выделения пара-ксилола из смеси исходного сырья, содержащей другие С8 ароматические углеводороды, в котором смесь исходного сырья вводят в контакт с цеолитным молекулярным ситом, в которое в результате ионного обмена введен, по меньшей мере, барий, в условиях, способствующих протеканию адсорбции, включающих температуру в диапазоне 99-149°С, при этом пара-ксилол селективно адсорбируют на молекулярном сите, а затем удаляют, используя поток десорбента, содержащего толуол, причем эффективность (IP) поддерживают на уровне, превышающем 90, при соотношении A/F в диапазоне от 0,5 до 0,7, при степени чистоты потока десорбента, превышающей 98 об.%, позволяющий проведение способа при соотношении L3/A в диапазоне от 1,6 до 2,3, где А = скорость моделированной циркуляции через объем селективных пор в ходе реализации способа, F = объемная скорость подачи смеси исходного сырья, L3 = расход жидкости через зону 3 и IP = квадратный корень величины (выход %, помноженный на степень чистоты %) для пара-ксилола в потоке продукта в виде экстракта.
2. Способ по п.1, в котором объемное отношение десорбента к исходному сырью поддерживают меньше, чем 1,2.
3. Способ по п.1, в котором общая концентрация C8 ароматических примесей в потоке десорбента менее, чем 2000 м.д.
4. Способ по п.1, в котором общая концентрация C8 ароматических примесей в потоке десорбента менее, чем 1000 м.д.
5. Способ по п.1, в котором в молекулярное сито в результате ионного обмена вводят барий и калий.
6. Способ по п.1, в котором десорбент содержит, по меньшей мере, 99,9% толуола.
7. Способ по п.1, в котором молекулярное сито представляет собой цеолит Х или цеолит Y.
8. Способ по п.1, где молекулярное сито представляет собой цеолит Y.
