  • Method for optimizing the operation of a hydrocarbon synthesis unit starting from synthesis gas, by controlling the partial pressure of CO
    Patent number: 8940802
    Abstract: A method is described for optimizing the operation of a reaction section for the synthesis of hydrocarbons from a feed comprising synthesis gas, operated in the presence of a catalyst comprising cobalt, said method comprising the following steps: a) determining the theoretical partial pressure of CO in the reaction section; b) optionally, adjusting the partial pressure of CO determined in step a) to a value of 4 bar or higher; c) determining a new value for the theoretical partial pressure of CO in the reaction section.

  • Process for stabilizing the performances of a catalyst for Fischer Tropsch reaction
    Patent number: 7968610
    Abstract: Process for maintaining the stability of performances of a catalyst for Fischer-Tropsch reaction, performed in a slurry bubble column reactor under a triphase system which comprises gradually increasing the PH2O/PH2 ratio and the PH2O/Z ratio, during the start-up phase, with Z=P0·(T/T1)4·e?(K2/(t·K3)) from 0.4 to 0.8, for a period of time not shorter than 100-150 hrs and not longer than 200-300 hours and, at the end of the start-up phase, maintaining the PH2O/PH2 and PH2O/Z ratios substantially equal to or lower than 0.8.
