Titanium-Doped Mesoporous Silica with High Hydrothermal Stability for Catalytic Cracking Performance of Heavy Oil

With the increasing attention to light oil, catalytic cracking process of heavy oil is being vigorously developed. The silicon hydroxyl groups on surface mesoporous silica materials can be used as weak acid centers preliminarily crack macromolecules. Herein, a strategy introducing titanium into skeleton for modification proposed increase active sites, well improve hydrothermal stability. After modification, material has more and shows better ability in deep oil. Notably, when content doping 2%, CT(2) catalyst exhibited best high-temperature stability, which suitable catalyst. This kind titanium-modified great application prospects cracking, may provide novel idea subsequent development.
