TiO 2-MCM-41的制备表征及选择性吸附脱硫研究
Preparation and Characterization of TiO 2-MCM-41 and Its Performance on the Desulfurization
摘要
Abstract
TiO 2-MCM-41 mesoporous molecular sieve(n (Si)/n (Ti)= 5 )was synthesized by heating reflux method,using titanium tetrabutoxide as the Ti source,MCM-41 as the carrier.The samples were investigated by means of XRD,FT-IR and N2 adsorption/desorption.The static and dynamic desulfurization experiment was carried out using fluid catalytic cracking (FCC)fuel oils.Properties of selective adsorptive desulfurization of FCC gasoline on the adsorbents have been investigated in this paper by a fixed-bed adsorption experiment and a GC-SCD technique.It was indicated thatthe titania homodisperses in the modified MCM-41,titania connected with the pendant OH groups of MCM-41 via Si—O—Ti bonds.After the load of TiO 2 ,the properties of adsorptive desulfurization on the adsorbents weresignificantly improved.The removal selectivities of the sulfur compounds in the gasoline changed slightly before and after the load of TiO 2 ,while the poor removal selectivities of benzothiophene,2/3-methylthiophene,2,3-dimethylthiophene,2,4-dimethylthiophene and 2,5-dimethylthiophene on MCM-41 and TiO 2-MCM-41 were the same.关键词
