A portion of the residual hydrocarbons and the solvent are separated from the slurry, and the solvent addition and separating steps are repeated until a ... 07/21/05 - 20050159295 - Method of restoring catalytic activity to a spent hydrotreating catalyst, the resulting restored catalyst, and a method of hydroprocessing A method of restoring catalytic activity to a spent hydroprocessing catalyst that has a first carbon concentration. The concentration of carbon on the spent hydroprocessing catalyst is reduced to provide a carbon-reduced catalyst having a second carbon concentration that is less than the first carbon concentration. The carbon-reduced catalyst is ... ### FreshPatents.com Support |
