Progress in application of TiO_2 support for catalytic diesel hydrodesulfurization

Advantages of TiO2 as the support of hydrodesulfurization(HDS)catalyst were presented,and the forming techniques and their applications of TiO2 support in the hydrodesulfurization of diesel were summarized.Great progress have been made in the forming techniques of TiO2 support,and the presently available TiO2 support can meet the requirements for diesel hydrodesulfurization.Several methods to improve the catalytic performance of HDS catalysts with TiO2 support were summarized as:(1)modification of the titania support with lanthanum and cerium,(2)introduction of promoters to the catalyst,(3)application of nano-structured TiO2 or titania nanotube with high surface area as support.
