The first commercial use of catalytic cracking occurred in 1915 when Almer M. McAfee of Gulf Refining Company developed a batch process using aluminium chloride (a Friedel–Crafts catalyst known since 1877) to catalytically crack heavy petroleum oils. However, the prohibitive cost of the catalyst prevented the widespread use of McAfee's process at that time. In 1922, a French mechanical engineer named Eugene Jules Houdry and a French pharmacist na… WebThis patent describes a process for the fluidized catalytic cracking (FCC) of an FCC feedstock. It comprises: passing the FCC feedstock and regenerated catalyst particles to a reactor riser and transporting the catalyst and feedstock upwardly through the riser thereby converting the feedstock to a gaseous product stream and producing spent catalyst …
