The invention relates to a method for improving yield in petroleum streams derived from coking processes. In a preferred embodiment, the invention relates to a method for regenerating filters employed to remove particulate matter from coker gas oil to improve coker gas oil yield and yield of upgraded coker gas oil products. It has been discovered that the accumulated foulant on the filter may be removed and filter permeability can be restored by contracting the filter with a treatment solution comprising hydrogen peroxide.
Procédé d'amélioration du rendement dans des flux de pétrole dérivés de processus de cokéfaction. Dans un mode de réalisation préféré, la présente invention concerne un procédé permettant de régénérer des filtres employés pour éliminer la matière particulaire du gasoil de cokéfaction afin d'améliorer le rendement en gasoil de cokéfaction et le rendement en produits valorisés de gasoil de cokéfaction. Il a été découvert que l'encrassement du filtre peut être supprimé et que la perméabilité du filtre peut être rétablie par mise en contact dudit filtre avec une solution de traitement contenant du peroxyde d'hydrogène.
