  • Distillate two-phase hydrogenation reactor and hydrogenation method
    Patent number: 9534178
    Abstract: A hydrogenation method and distillate two-phase hydrogenation reactor in which the size of an upper space of the reactor is greater than that of a lower catalyst bed part. The reactor comprises 2 to 4 catalyst beds. An inner component for gas replenishment and for stripping a liquid-phase stream containing impurities is arranged between at least one adjacent catalyst bed and comprises a separator plate and exhaust pipes. The separator plate is provided with multiple downcomer through holes. The separator plate is connected with a plurality of exhaust pipes. The exhaust pipes are vertically arranged above the separator plate. The top parts of the exhaust pipes are in contact with the lower part of the upper catalyst bed.

  • DISTILLATE OIL HYDROGENATION DEACIDIFICATION CATALYST CONTAINING MOLECULAR SIEVE, PREPARATION AND USE THEREOF
    Publication number: 20130316894
    Abstract: Provided are a distillate oil hydrogenation deacidification catalyst containing a molecular sieve, preparation and use thereof. In this catalyst, the weight of the catalyst, on the basis of 100%, is 1-5% magnesium calculated as an oxide, 1-20% alumino-phosphate molecular sieve and/or aluminosilicate molecular sieve; 1-10% Co and/or Ni; 5-30% Mo and/or W, and the balance is aluminium oxide. The catalyst is prepared through forming, dipping and baking. The catalyst is very active in hydrogenation deacidification, and also in hydrodesulfurization and hydrodenitrogenation.
