Increase the reaction temperature, increase the pressure (hydrogen partial pressure), reduce the space velocity, and increase the hydrogen partial pressure. The main approach is to increase the reaction temperature.
Increase the temperature, enhance catalyst activity, improve the purity of recycled hydrogen, raise the reactor pressure, and modify the properties of the feed oil. Temperature-oriented
