ABSTRACT OF THE DISCLOSURE The present invention relates to a process for the treatment of a hydrocarbon charge by high temperature ultra- filtration, said process comprising the steps of circulating said charge in a module comprising at least one mineral ultrafiltration barrier coated with a sensitive mineral layer of at least one metal oxide and of operating at a temperature higher than 100°C. The barrier, which preferably has a ceramic or metallic support, is coated with a sensitive layer selected from the group comprising titanium dioxide, magnesium oxide, aluminium oxide, spinel MgAl2O4, silica. The invention is applicable to the regeneration of a waste oil and to the reduction of the rate of asphaltenes in a hydrocarbon charge.
