摘要： The invention is directed to methods of transfering catalyst particles into and within 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 transfer methods provide appropriate mechanisms for transporting catalyst into and within a reactor to protect against loss of catalytic activity that can occur due to contact with water molecules.
