    Abstract: A platinum group component catalyst, used in a hydroconversion unit comprising a plurality of reactors in series, is regenerated to remove carbonaceous matter from the catalyst without contaminating the catalyst with sulfur compounds by purging the hydroconversion unit of hydrocarbons, circulating an inert gas through the hydroconversion unit at a pressure of from 50 to 1000 p.s.i.g., controlling the inlet temperature in all but the terminal reactor to below about 500* F. while controlling the inlet temperature in the terminal reactor at from 500* to 700* F., then introducing an oxygen-containing gas into the terminal reactor to remove carbonaceous matter from the catalyst but insuring that the oxygen is discontinued when the exit stream from the terminal reactor contains more than about 0.1 volume percent oxygen.

    Abstract: In a process for reducing the amount of oxygen in the effluent gases from a catalytic cracker regenerator, and thus controlling after-burning, a reducing gas such as carbon monoxide or hydrogen is injected into the regenerator above the bed of catalyst being regenerated. Preferably the amount of reducing gas is automatically controlled responsive to the oxygen content of the effluent flue gases from the regenerator. Preferably the reducing gas is introduced through at least three nozzles into the regenerator. Preferably the nozzles are located in substantially different positions within the regenerator above the bed of catalyst being regenerated, and the amount of reducing gas flow through each nozzle is controlled responsive to oxygen content of the effluent flue gases from the regenerator.

    Abstract: A fluidized bed reactor, vertically divided into two or more upper compartments or chambers which are connected to each other by a lower mixing chamber, provides a fluidized bed system wherein the fluidized catalyst can be used in one of the upper chambers and then by random movement pass into the lower mixing chamber hence into another upper chamber where it can be regenerated. This compact system requires a minimum of equipment and gives a maximum of operating efficiency.
