              JY-HG Heavy Oil Hydrogenation Protective Agent

              JY-HG catalyst is a hydrogenation protective agent .According to the principle of activity from low to high, a series of hydrogenation protectants adopts the shape of special-shaped particles to retain a high porosity, ensure a high scale capacity and a certain hydrogenation demetallization capacity, and play a protective role for the main catalyst.  
              JY-HG hydroprotectors can not only meet the needs of residual oil hydrotreating units, but also be used in other heavy and inferior distillate oil hydroupgrading and hydrofining processes.
