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.
