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. WebOct 6, 2024 · Our FCC Catalysts provide the main catalytic cracking power in the unit and need to be optimized per feedstock and desired output. Providing tailored FCC solutions for various feedstocks as well as options for refineries that want feed flexibility, BASF catalysts coupled with our technical expertise provide sustainable solutions for all FCC units.
