摘要： A process for the conversion of heavy oils comprising sending the heavy oil to hydrotreatment, of the high severity type, in the presence of high concentrations of a suitable hydrogenation catalyst dispersed in slurry phase, effected in a suitable solid accumulation reactor capable of operating stably in the presence of solids deriving from and generated by the feedstock charged, wherein the hydrogen or mixtures thereof is fed at suitable flow-rates and suitably distributed, obtaining the conversion products in vapour phase directly in the reactor.

摘要： Process for the conversion of heavy feedstocks selected from heavy crude oils, distillation residues from crude oil or catalytic treatment, 'visbreaker tars', 'thermal tars', bitumens from 'oil sands' liquids from coals of different origins and other high boiling feedstocks of a hydrocarbon origin, comprising the following steps: • mixing the heavy feedstock with a suitable hydrogenation catalyst and sending the mixture obtained to a first hydrotreatment area (HTl) to which hydrogen or a mixture of hydrogen and H2S are introduced; • sending the effluent stream from the first hydrotreatment area (HTl), containing the hydrotreatment reaction product and the catalyst in dispersed phase, to a first distillation area (Dl) having one or more flash steps and/or atmospheric distillation and/or vacuum distillation whereby the various fractions coming from the hydrotreatment reaction are separated; • sending at least part of the distillation residue (tar) or liquid leaving the flash unit of the first distillation area (Dl), containing the catalyst in dispersed phase, rich in metallic sulfides produced by demetallation of the feedstock and optionally minimum quantities of coke, to a deasphalting area (SDA) in the presence of solvents obtaining two streams, one consisting of deasphalted oil (DAO), the other containing asphaltenes and solids to be sent to disposal or to metal recovery; • sending the stream consisting of deasphalted oil (DAO) to a second hydrotreatment area (HT2), to which hydrogen or a mixture of hydrogen and H2S and a suitable hydrogenation catalyst are introduced; • sending the effluent stream from the second hydrotreatment area (HT2), containing the hydrotreatment reaction product and the catalyst in dispersed phase, to a second distillation area (D2) having one or more flash and/or distillation steps whereby the various fractions coming from the second hydrotreatment area are separated; • recycling at least part of the distillation residue or liquid leaving the flash unit of the second distillation area (D2), containing the catalyst in dispersed phase to the second hydrotreatment area (HT2).

摘要： System and relative process for the complete and high productivity hydroconversion of heavy oils essentially consisting of a solid accumulation reactor and a stripping section of the conversion products outside or inside the reactor itself. In particular, the system proposed consists of a solid accumulation hydroconversion reactor in which the solids deriving from and generated by the feedstock treated (metals in the form of sulphides and coke) are accumulated, up to very high levels, and a hot gas stripping section of the reaction liquid, designed in relation to the type of reactor adopted, for the direct and continuous removal of the conversion products, including high-boiling products.
