摘要: 采用高温水热合成法在强碱性条件下,成功制备了有序性很高的三八面体结构的皂石,同时对其进行铝柱柱撑,通过XRD、27Al MAS-NMR、N2吸附脱附、吡啶红外、TGA-DTA、TEM等技术对材料进行了物化表征,并用临氢异构表征了材料的催化性能. 结果表明:层柱皂石具有很好的层柱结构,热稳定性可达800℃以上,且具有较好的正癸烷临氢异构转化率和异构产物收率.  

关键词: 皂石, 柱撑, 层柱皂石, 正癸烷, 临氢异构

Abstract: Well-ordered trioctahedral saponites were successfully synthesized in strong basic system under high temperature, and were intercalated with Keggion ions. XRD, 27Al MAS-NMR, N2 adsorption and desorption , FTIR spectra of pyridine adsorption, TGA-DTA and TEM were used for the characterization of the synthetic aluminum-pillared saponites. The results illustrated that pillared saponites were highly-ordered and thermal stable above 800℃.Besides,after being pillared by aluminium oligmer,the Al-pillared synthetic saponite showed high conversion and hydroisomerization yield in the catalytic reaction of n-decane.

Key words: saponite, intercalated, pillared-saponite, n-decane, hydroisomerization
