The invention is directed to methods of shutting down reaction systems. The reaction systems are those that use catalysts that comprise molecular sieves, particularly metalloaluminophosphate molecular sieves, especially metalloaluminophosphate molecular sieves which are susceptible to loss of catalytic activity due to contact with water molecules. The methods provide appropriate mechanisms of stopping feed to the reactor and unloading catalyst to protect against loss of catalytic activity that can occur due to contact with water molecules. Изобретение направлено на способы отключения реакционных систем. Реакционные системы представляют собой такие системы, в которых применяют катализаторы, содержащие молекулярные сита, в частности металл-алюмофосфатные молекулярные сита, особенно металл-алюмофосфатные молекулярные сита, которые подвержены потере каталитической активности вследствие контакта с молекулами воды. Способы обеспечивают подходящие механизмы прекращения подачи сырья в реактор и выгрузки катализатора, позволяющие защитить его от потери каталитической активности, которая может происходить вследствие контакта с молекулами воды.
