METHOD OF STARTING UP A REACTION SYSTEM

摘要

The invention is directed to methods of starting up 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 heating and loading the activated molecular sieves to protect against loss of catalytic activity that can occur due to contact with water molecules.
