  • Method of enhancing finished catalysts
    Patent number: 5438028
    Abstract: A method of enhancing the activity of a catalyst for the hydroprocessing of hydrocarbons, comprising:(a) applying a modifying element dissolved in a solvent onto the surface of a finished catalyst;(b) drying said modified finished catalyst to remove all free solvent from said catalyst;(c) optionally, heating said dried, modified finished finished catalyst at a temperature of about 120.degree. C. to about 1000.degree. C. at a rate of 1.degree.-20.degree. C. per minute, and holding said dried catalyst at a temperature of about 120.degree. C. to about 1000.degree. C. up to 48 hours to provide an enhanced finished catalyst; and(d) recovering said enhanced finished catalyst.
    Type: Grant
