摘要： A process and associated apparatus for the cooling of hot fluidized solid particles. The particles flow from a dense phase fluidized bed into the shell side of a vertically oriented shell and tube heat exchanger where cooling occurs via indirect heat exchange with a cooling media circulating in the tubes. The extent of cooling is controlled by the varying of the heat transfer coefficient between the tubes and particles in the heat exchanger which are maintained as a dense phase fluidized bed. The coefficient is varied by varying a combination of the variables comprising the quantity of fluidizing gas to the fluidized bed in the heat exchanger and the quantity of particle flow through that bed. The process has particular applicability to a combustive regeneration process and most particular applicability to the FCC process.

摘要： A catalyst regeneration process and apparatus for the oxidative removal of coke from a coke contaminated fluid catalyst. The process comprises a high temperature coke combustion zone, a catalyst disengagement zone and an external heat removal zone comprising a shell and tube heat exchanger. Catalyst is cooled by passing it through the shell side of the heat exchanger with a cooling medium through the tube side. A mixture of coke contaminated catalyst, oxygen containing gas, and cool regenerated catalyst from the heat removal zone are contacted in the high temperature combustion zone, the temperature of which is controlled by adjusting the rate at which fluidizing gas is passed to the bottom portion of the shell of the heat exchanger which varies the degree of turbulence of the fluidized bed in the shell side and thus the heat transfer coefficient at the outside surface of the tubes which in turn varies the quantity of heat transferred to the cooling medium in the tubes.

摘要： A catalyst regeneration process and apparatus for the oxidation of coke from a spent catalyst, said coke being converted to CO, and for the conversion of the CO to CO.sub.2. Hot regenerated catalyst is recycled from a dense bed in the regeneration zone to mix with incoming spent catalyst in a riser-mixer. The riser-mixer operates in dense phase and is supplied with a relatively small amount of a fluidizing medium, preferably air. After the mixing of spent and fresh catalyst is substantially completed, a relatively large amount of a regenerating gas, preferably air, is admixed with the catalyst mixture, and some coke oxidation occurs. The balance of coke oxidation takes place in a downstream-situated regeneration zone of substantially conventional design. The regenerating gas addition is preferably made at the base of a cone-shaped combustor in order to provide a venturi effect which ensures good air-catalyst mixing.

摘要： A moldable heat shield with a needled nonwoven core layer and needled nonwoven shell layers. The core layer has a blend polyester staple fibers and low melt polyester staple fibers. The shell layers have a blend of staple fibers of partially oxidized polyacrylonitrile, and staple fibers of polyester, and staple fibers of a low melt polyester. The layers are needled together such that fibers from the core layer do not reach the outer surfaces of the shell layers. The shell layers are calendared such that an outer surface layer is formed thereon, which provides the moldable heat shield with a water and oil resistant surface.
