Аннотация
Термический анализ полученных катализаторов процесса пиролиза хлористого метила проводили на дериватографе Q-1500D. Пористую структуру образцов изучали методом низкотемпературной адсорбции азота на приборе NOVA 1200 E. Удельную поверхность образцов определяли методом БЭТ, средний размер мезопор – методом BJH. Основная продукция – ненасыщенные углеводороды C2-C4. Также было мало побочных продуктов, в основном насыщенных углеводородов с открытой цепью (C1-C4). Для реализации процесса была изучена активность таких катализаторов, как ЮКС, Fe2O3 (ЮКСFe), SiO2 (ЮКСSi), (ЮКСМg) и определен следующий порядок активности: ЮКСМg > ЮКСFe > ЮКСSi > ЮКС. В результате исследований создана технологическая схема получения монохлорметана и получения этилена и пропилена для реализации процесса и проанализированы результаты.
