Abstract

Изобретението се отнася до превръщане на изходен материал от тежки ароматни съединения в по-леки ароматни продукти, като бензен, чрез контактуване нафракция от С9+ ароматни съединения и толуен върхупърви и втори катализатор. Първият катализатор включва зеолит с индекс на напрежение от 0,5 до 3 и компонент за хидрогениране. Вторият катализатор включва междинен порест зеолит с индекс на напрежение от 3 до 12 и силициев диоксид и двуалуминиев триоксид в съотношение най-малко 5, при което количеството на съизпарителите намалява или се елиминира.
