Catalytic behavior of MFI zeolites differing in thickness of nanosheets and ordering was studied in annulation of phenols, and compared with 3 D zeolites BEA and MFI containing large or medium pores as well as with micro/mesoporous zeolite USY. The highest conversions of phenols studied were achieved over ordered hexagonally mesostructured zeolite with 1.7 nm wall size, followed by materials possessing
研究了纳米管厚度不同的MFI沸石在酚的环化中的催化行为,并将其与3D沸石BEA和MFI含有大或中孔的微孔沸石以及US /微米/中孔沸石进行了比较。所研究的苯酚的最高转化率是在壁尺寸为1.7 nm的有序六角形介孔结构沸石上实现的,随后是具有2.1和2.7 nm纳米片厚度的材料。这对应于所研究材料的表面积减小。对于较大的动力学直径[苯酚(0.66 nm)<1-萘酚(0.80 nm)<2-萘酚( 0.89nm)]。USY沸石的转化率更高(苯酚的转化率为32%,6%,25%,
