An ebullated bed hydroprocessing system is upgraded and operated at modified conditions using a dual catalyst system to produce less fouling sediment. The less fouling sediment produced by the upgraded ebullated bed reactor reduces the rate of equipment fouling at any given sediment production rate and/or concentration compared to the sediment produced by the ebullated bed reactor prior to upgrading. In some cases, sediment production rate and/or concentration are maintained or increased, after upgrading the ebullated bed reactor, while equipment fouling is reduced. In other cases, sediment production rate and/or concentration are increased, after upgrading the ebullated bed reactor, without increasing equipment fouling. In some cases, sediment production rate and/or concentration are decreased by a given percentage, after upgrading the ebullated bed reactor, and the rate of equipment fouling is decreased by a substantially greater percentage.

An inflow base which is permeable to process air and includes openings for the process air which flows thought the inflow base. The inflow base is arranged in the fluidizing apparatus in a manner rotatable about an axis Z of the fluidizing apparatus and subdivides this into a distribution chamber and into a vortex chamber. The inflow base of the fluidizing apparatus includes at least a first and a second inflow base plate, wherein one of the inflow base plates at its outer end includes or forms a sealing element.

A device for processing a flow of particulate material by contact with a gas flow includes a housing defining a processing chamber. This chamber includes a gas distribution plate having openings. The gas distribution plate separates a lower gas plenum from a solid-gas contact zone. The contact zone has at least one cylindrical partition upstanding from the gas distribution plate dividing an inner section from an adjacent annular outer section. The at least one partition is provided with a transfer opening for the particulate material. The housing is also provided with an inlet for supplying particulate material to the inner section and an outlet for discharging processed particulate material from the annular outer section.
