  • Colour sorting of catalyst or adsorbent particles
    Patent number: 8307985
    Abstract: Process for separating at least one type of catalyst or adsorbent particles having similar colors characterized in that such particles undergo an oxidative heating treatment for generating particle of different colors, and then particles are separated using a color sorting process for separating at least one type of particles.
    Type: Grant
    Filed: June 26, 2008
    Date of Patent: November 13, 2012
    Assignee: IFP Energies nouvelles
    Inventors: Pierre Dufresne, Maxime Meens, Mickaël Bremaud
  • Process for sulfurization or presulfurization of solid particles of a catalyst or an adsorbent
    Patent number: 8088705
    Abstract: The invention relates to a process for incorporating sulfur in the porosity of the solid particles of a catalyst for the conversion of hydrocarbons or an adsorbent. This process is carried out off-site in the presence of hydrogen sulfide that is pure or diluted in hydrogen or nitrogen, a process in which said particles are made to rise or fall in a sulfur incorporation zone that comprises at least one vibratory helical coil that is essentially tubular in shape and that comprises at least two turns, whereby said particles are subjected to a temperature profile over the majority of their path in said coil and whereby said particles are brought into contact with at least one fluid on at least one portion of their path.
