Product characteristics and Application

Diesel fuel hydrogenation catalyst LYT-703 with modified carbonization γ -AL2O3 as carrier, containing tungsten and molybdenum nickel active metal components and additives of diesel hydrotreating catalyst. The catalyst has excellent hydrofining performance, can greatly improve the catalytic cracking diesel cetane number of sixteen.LYT-703 diesel oil hydrogenation the modified catalyst for low or medium under the condition of the diesel such as catalysis, coker gatch hydrogenation, reducing diesel sulfur, nitrogen and aromatic content, raise Diesel Cetane Number sixteen, to reach the high quality diesel oil hydrotreating index, the catalyst can also be used for poor quality catalytic cracking feedstoc
