Abstract
The present invention describes improved FCC and TCC stripper operations by incorporating a stripper operated at a reduced pressure. The improved strippers of the invention will increase total liquid hydrocarbon yield while reducing the coke load on the regenerator. Novel porous TCC bead catalysts are disclosed wherein at least 1/3 of the pore volume of catalyst pores having a pore diameter of at least 3000 Angstroms. These macropores facilitate flash vaporization of hydrocarbons in a stripping zone of the spent catalyst upstream of a regeneration zone.
