1. Feature and purpose
     LYT-709A Inferior Diesel Hydro-Upgrading Catalyst is made with the carrier of molecular sieve modification g-Al2O3 made from the raw materials of carbonized aluminum hydroxide dry glue and special molecular sieve, the active component of Mo and Ni and the method of total immersion. This catalyst has not only the certain ability to open loop of polycyclic aromatic hydrocarbons, the hydrogenation removal ability for complex sulfur-containing compounds and nitrogenous compounds with a clover shape, but also both the hydrorefining performance and hydro-upgrading performance for inferior diesel.
