1.Features and purpose
LYT-707A catalyst is a composite catalyst of catalytic cracking gasoline selective hydrodesulfurization with the carrier of γ－Al2O3 modified carbonization method and the active components of Co-Mo. This composite catalyst has the feature of high activity of selective hydrodesulfurization and low activity of olefin hydrogenation to be used as the technology of catalytic cracking gasoline selective hydrodesulfurization with the low loss of gasoline octane value.

4.Package, transportation and storage
The product is put into the 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.
