Claims (7)
1. Способ разделения, в котором исходный поток, содержащий молекулы продуктов по меньшей мере двух различных типов, выбранных из группы, включающей углеводороды, оксигенированные продукты и их смеси, подают к первой стороне мембраны молекулярного сита, а поток растворенного вещества удаляют со второй стороны этой мембраны, отличающийся тем, что его осуществляют в присутствии водорода по меньшей мере в одном из потоков исходного материала и растворенного вещества.
2. Способ по п. 1, в котором водород добавляют по меньшей мере в один из потоков исходного материала и растворенного вещества.
3. Способ по п. 1, в котором водород добавляют в исходный поток.
4. Способ по п. 1, в котором водород содержится в концентрации от примерно 0,1 мол.% в пересчете на исходный поток до примерно 60 мол.% в пересчете на исходный поток.
5. Способ по п. 1, в котором процесс разделения осуществляют в температурном интервале от примерно 170 до примерно 300°С.
6. Способ по п. 1, в котором растворенным веществом является параксилол.
7. Способ по п. 1, в котором водород добавляют в растворенное вещество.
