不同水解条件下Ti-MCM-41介孔分子筛的合成及其催化氧化脱硫性能
Study on preparation and catalytic oxidation desulfurization performance of Ti-MCM-41 synthesized at different hydrolysis conditions
摘要
Abstract
Ti-MCM-41 mesoporous materials were synthesized through improved hydrothermal method with solution of cetyltrimethylammonium bromide (CTAB) and sodium hydroxide as template, tetraethylorthosilicate (TEOS) as silica source,tetraethylorthosilicate (TBOT) as titanium source. The influence of temperature of hydrolysis (30℃、60℃) and inhibitors of alcohols were investigated respectively. Products were characterized by XRD,SEM,TEM and other means. The results indicate that the molecular sieves obtained exhibit regular long-range ordered hexagonal mesoporous structure. The sample at hydrolysis temperature of 30℃ shows better crystallinity and long-range ordered structure. Desulfurization rate reached 96.7%under the condition:catalyst amount 0.1g/10mL(oil), reaction time 30min and desulfurization temperature 40℃. It can be summarized that lattice defects and poor long-range order are in favor of the removal of sulfur from diesel.关键词
