  • Wet start-up method for hydrogenation unit, energy-saving hydrogenation process and hydrogenation apparatus
    Patent number: 9574141
    Abstract: The present invention relates to a wet start-up method for hydrogenation unit, an energy-saving hydrogenation process, and a hydrogenation apparatus. The method involves heating a start-up activating oil to a specific temperature and flowing the heated oil through a bed of hydrogenation catalyst bed, so that the temperature at the catalyst bed layer is increased to 180±10° C. or above by means of heat exchange and the reaction heat generated from activation in the start-up method.
    Type: Grant
