WebFor some zeolitic catalysts like FCC, feed contaminants like sodium also promote sintering by acting as a flux agent which lowers the catalyst support melting point. ... Catalyst sintering can be avoided by controlling the temperature of the burn front during the catalyst regeneration process. If the temperature gets too high, there can be ... WebDec 11, 2012 · This carbon, known as catalyst coke, adheres to the catalyst, reducing its ability to crack the oil. The coke on the spent catalyst is burned off, which reheats the catalyst to add heat to the FCC …
WebJul 1, 2024 · Regeneration of spent catalyst is key to the successful operation of the fluid catalytic cracking (FCC) unit. The coke laden spent catalyst from oil cracking in the FCC riser is burned off in the regenerator. The heat generated raises the circulating catalyst temperature and, in turn, helps crack the oil to valuable products in the riser. WebThe fluid catalytic cracking (FCC) process is an important refinery process in the United States. Catalyst regeneration is an essential part of this process. In the reactor section …
