Abstract

Изобретението се отнася до метод за термичен крекинг с понижено коксуване, по-специално до производство на олефини в олефинов завод, включващ пиролизна пещ с пиролизни тръби, в които въглеводородите се крекират. По метода въглеводородната суровина се въвежда почти свободна от фосфорсъдържащи съединения в пиролизна пещ, работеща при пиролизни условия. Получава се олефинсъдържащ ефлуент. Пиролизните тръби имат ефективен пасиватор на металните активни центрове, свързан с откритата метална повърхност чрез въвеждане на активен пасиватор в пещта притемпература, по-висока от тази на кондензация на водата.
