Abstract
A hydrocarbon conversion-catalyst regeneration riser means system with interconnecting standpipes is described which relies upon catalyst separating and collecting vessels about the upper end of each riser means, means for contacting collected catalyst with gaseous material, standpipe means for passing collected catalyst in each vessel means to the lower portion of each riser means opposite from that from which obtained, a standpipe for passing collected regenerated catalyst directly to a lower bottom portion of said regeneration riser means and another standpipe for passing collected regenerated catalyst into the standpipe passing spent catalyst to the lower portion of the regeneration riser.
