Abstract： The technical characteristics of 3.4 Mt/a IsoTherming full-liquid-phase die
sel hydroprocessing unit were discussed. Compared with trickle bed hydroprocessing technologies， IsoTherming technology realized that all catalyst beds were immersed into full liquid phase oil， the reaction was close to isothermality， thus high yield of targeting products was achieved， less high pressure equipments were used， heat lose was less， meanwhile，the operating cost was significantly reduced. The introduction of this technology has a certain reference significance for the diesel hydrotreating industry.
