Abstract
An additive for hydroconversion processes includes a solid organic material having a particle size of between about 0.1 and about 2,000 μm, a bulk density of between about 500 and about 2,000 kg/m3, a skeletal density of between about 1,000 and about 2,000 kg/m3 and a humidity of between 0 and about 5 wt %. Methods for preparation and use of the additive are also provided. By the use of the additive of the present invention, the hydroconversion process can be performed at high conversion level.
Claims25
A hydroconversion process, comprising feeding (a) a heavy feedstock containing at least one feedstock metal selected from the group consisting of vanadium and nickel, (b) an unsupported catalyst emulsion containing at least one group 8-10 metal and at least one group 6 metal, (c) hydrogen and (d) an organic additive to an upflow bubble column reactor defining a hydroconversion zone under hydroconversion conditions to produce an upgraded hydrocarbon product and a solid carbonaceous material containing said group 8-10 metal, said group 6 metal, and said at least one feedstock metal, wherein the organic additive comprises a solid organic material having a particle size of between about 0.1 and about 2,000 μm, a bulk density of between about 500 and about 2,000 kg/m3, a skeletal density of between about 1,000 and about 2,000 kg/m3 and a humidity of between 0 and about 5 wt %, and treating the solid carbonaceous material to recover said group 8-10, said group 6 and said at least one feedstock metals.
