1. Feature and purpose
LYT－UDSⅠ Diesel Hydrorefining Catalyst is made with the carrier of the modified γ－Al2O3, the active component of Co-Mo and total immersion. It will adjust the pore structure of carrier and the ratio of Mo and Co suitably according to the molecular size of coked diesel, straight-run diesel, catalytic diesel and coked gasoline. By modifying aluminum oxide, it can adjust the interaction between carrier and active metals, control to produce the interaction between active metals and carrier, make active metals more complete sulfuration, produce more and more active centers in edges and improve the hydrodesulfurization activity of catalysts.
