Abstract

Описана многоцелевая дистилляционная колонна-реактор, которая может быть применена для получения третичного амилметилового эфира посредством взаимодействия изоамиленов, содержащихся в продуктах крекинга легкой нафты, с метанолом. Две реакционные дистилляционные зоны расположены выше отгонной секции. Эта отгонка, в дополнение к удалению продукта ТАМЭ, также удаляет Cи более тяжелые компоненты. Первая дистилляционная реакционная зона содержит катализатор гидроочистки для удаления диолефинов и меркаптанов. Вторая дистилляционная реакционная зона содержит кислотную катионообменную смолу для реакции этерификации, и вся колонна служит для фракционирования многокомпонентной реакционной системы (реагенты, инертные соединения, продукты и примеси) одновременно с многочисленными реакциями.

  1. Описана многоцелевая дистилляционная колонна-реактор, которая может быть применена для получения третичного амилметилового эфира посредством взаимодействия изоамиленов, содержащихся в продуктах крекинга легкой нафты, с метанолом. Две реакционные дистилляционные зоны расположены выше отгонной секции. Эта отгонка, в дополнение к удалению продукта ТАМЭ, также удаляет C6 и более тяжелые компоненты. Первая дистилляционная реакционная зона содержит катализатор гидроочистки для удаления диолефинов и меркаптанов. Вторая дистилляционная реакционная зона содержит кислотную катионообменную смолу для реакции этерификации, и вся колонна служит для фракционирования многокомпонентной реакционной системы (реагенты, инертные соединения, продукты и примеси) одновременно с многочисленными реакциями.
