By density functional calculations, it was confirmed that for the reaction of RSCC (residual oil selective catalytic cracking),the catalysts such as zeolite ZSM-5 will endure an enhanced thermal stability when some La3＋ ions are introduced. Due to the strong interaction between La3＋ and the zeolite, the Al－O bond, which would have been easily broken, gets stronger and the process of dealumination is thus effectively retarded. Through the reduction of La(OH)2＋ when heated, LaO(OH) is most likely formed, which can interact with zeolite ZSM-5 and turns out to the structure of Z－La(OH)2＋ or Z-LaO(OH) after geometrical optimization. Z－La(OH)2＋ remains stable under normal conditions; however, as the temperature is raised, it will change slowly into Z-LaO(OH),which stays stable at high temperature. The La3＋ ion in Z-LaO(OH) can offer Lewis acid as the active site for reactions, we believe that this result can provide valuable insight into the elucidation of catalytic mechanism.
