摘要:
The invention concerns a process for hydroconversion of a hydrocarbonaceous feedstock comprising: - a preparation step of at least one catalyst in one or more preparation reactor upstream from a reaction section, wherein - (i) at least one preparation reactor feeds one or more reactor of the reaction section, or - (ii) preparation reactors are dedicated for catalysts fed to at least a hydroconversion reactor or at least a hydrotreatment reactor of the reaction section;
- a separation step of solids contained in the liquid effluents issued from the reaction section, - a treatment step of residues issued from separation section, comprising a partial oxidation step wherein said residues are partially oxidized to produce carbon monoxide, hydrogen an a metal containing residue. Such process permits improving of products quality, operation of the separation section, recovering of catalytic metals contained in the feed and supplying hydrogen to the reaction section.
摘要:
The instant invention discloses a method for the separation of solids contained in a solid containing treated hydrocarbon feedstock issued from an industrial unit, wherein an ultimate reactor is fed with an ultimate catalyst, an ultimate hydrocarbon feedstock and an ultimate hydrogen containing gas, and wherein after reaction, the resulting ultimate treated hydrocarbon feedstock undergoes a liquid-solid filtration before a final fractionation is performed.
摘要:
The invention concerns a process for upgrading heavy hydrocarbonaceous feedstocks in at least one hydroconversion reactor for hydroconversion of said heavy hydrocarbonaceous feedstocks and in at least one hydrotreatment reactor for hydrotreatment of said heavy hydrocarbonaceous feedstocks, said process comprising the preparation of two or more catalysts, each catalyst being prepared from one or more catalyst precursor in at least one specific preparation reactor, said catalyst precursor containing at least one transition metal selected from group IIA, IIIB, IVB, VB, VIB, VIIB, VIII, IB or IIB of the periodic table of elements, and each preparation reactor feeding one or more hydroconversion or hydrotreatment reactor, each catalyst contained in preparation reactors being dedicated to hydroconversion or hydrotreatment of said feedstocks. Such a process permits to obtain, under continuous operating conditions, products of better quality.
