Latest Patents

One of his latest patents is the "Fluidized catalytic cracking regeneration process." This process describes a method for regenerating spent, coke-contaminated fluidized cracking catalyst by burning coke with a molecular oxygen-containing regeneration gas in a fluidized dense phase bed. The process also includes a method for supplying additional oxygen to a dilute phase above the dense phase bed for the combustion of carbon monoxide, ensuring that nearly all carbon monoxide is converted to carbon dioxide. Furthermore, it provides a method for transferring heat from the dilute phase back to the bottom of the fluidized dense phase bed.

Another significant patent is the "Fluidized cracking catalyst regeneration apparatus." This apparatus is designed for the regeneration of spent, coke-contaminated fluidized cracking catalyst. It employs a molecular oxygen-containing regeneration gas in a fluidized dense phase bed and ensures the conversion of carbon monoxide to carbon dioxide. The apparatus includes means for transferring heat from the top to the bottom of the regeneration system, utilizing catalyst as the transfer medium, and features conical standpipe means for deaerating regenerated catalyst.
