The residue fluid catalytic cracking (RFCC) additives containing macropores were prepared with 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) of room temperature ionic liquid modified halloysite as matrix and the USY zeolite as base. X-ray powder diffraction and N₂ adsorption-desorption were employed for characterization of the crystallinity and macroporous structure of RFCC additives. The performance of RFCC additives were carried out over a confined fluidized bed fluidized bed (ACE-MODEL R+ MM) with Jinan FCC feedstock and Jinan FCC balance catalyst. It was found that the ionic liquid strongly interacted with the surface hydroxyl of halloysite firstly during the preparation of RFCC additives, and then the strong interaction between ionic liquid and halloysite effectively prevented the binder and USY zeolite to enter the inner of nano-tube of halloysite. At last, the macropores in RFCC additives were produced when the additives were calcinated and the ionic liquid was removed at higher temperature. The resulting macroporous additive exhibited good catalytic cracking activity and high yield of gasoline.
