Abstract

Методът ще намери приложение за регенериране на зеолитен алкилиран или трансалкилиран катализатор, частично отработен и подложен на топлинно третиране с ароматен въглеводород. По метода регенерираните отработени зеолитни катализатори се извличат приполучаването на моноалкилирани ароматни въглеводороди чрез алкилиране на ароматен въглеводороден субстрат с алкилиращ агент, избран от С2-С4 олефини,изопропанол и смеси от изопропанол с пропилен, или чрез трансалкилиране на ароматен въглеводороден субстрат с един или повече полиалкилароматни въглеводороди. Методите за алкилиране или трансалкилиране се провеждат най-малко в частично течна фаза и в присъствието на катализатор от зеолитен вид.
