Her innovative approach has led to the development of a patented process that enhances the efficiency of heavy feedstock cracking.

Latest Patents

Maria Celia Da Rocha holds a patent for a process for the fluid catalytic cracking of heavy feedstocks. This process operates under a heat balance regime, where one or more catalyst coolers external to the regenerator cool a stream of regenerated catalyst. A portion of this stream returns to the regenerator, while a portion of the cooled regenerated catalyst is mixed with the non-cooled regenerated catalyst at a temperature significantly lower than the regenerator temperature. This admixture is then brought into contact with the hydrocarbon feed to be cracked. The result is a control of the catalyst circulation that is independent of the unit's heat balance, minimizing thermal cracking and consequently reducing coke and fuel gas products. Maria holds 1 patent for this innovative process.
