3. Applying conditions
     (1) Material: Being applicable to the hydroprocess of distillate and heavy oil.
     (2) Operating pressure: 40~20.0Mpa
     (3) Applicable temperature: 250~400℃
     (4) Liquid airspeed: 10.0~20.0h-1
4. Package, transportation and storage
     LYT―704B protective agent for hydroprocessing catalyst is put into hard fiber cans with covers and inner plastic bags. It has the name, net weight, batch No. and production date on the outside of cans. It will be covered and kept from damp, vibration and strong impact. It is forbidden to roll and throw the catalyst barrels in transportation and handling. It should be stored in the dry and ventilated storehouses and paid attention to moisture-proof. It is forbidden to contact with acids and the hazardous substances of alkali chemical reagent to avoid affecting the activity of catalyst.
