| 摘 要： | 考察了不同K含量对Pt -Sn/Al2O3催化剂异丁烷脱氢制异丁烯的影响,并通过比表面-孔分布测定、扫描电镜、吡啶吸附-红外等一系列表征手段探讨了K对Pt -Sn/Al2O3催化剂物理结构及表面酸性的影响.结果表明,加入K能有效降低催化剂表面的酸量,且主要表现在强L酸量的降低；随着K含量的增多,催化剂表面酸量减少,异丁...

| Abstract: | The effects of potassium content on the acidity and isobutane dehydrogenation properties of Pt-Sn/Al2O3 catalyst were studied by N2 adsorption and desorption techniques,scanning electronic microscope(SEM),pyridine-IR and isobutane dehydrogenation.The results show that the acid quantity was reduced due to potassium adding,especially the number of acid sites with strong acidity.The acid quantity decreases and the isobutane dehyrogenation selectivity increased obviously with the increase of potassium.It was al... |
