HIGH ACTIVITY SMALL CRYSTAL ZSM-12 |
摘要 |
A porous, crystalline material is described having the framework structure of ZSM-12 and a composition involving the molar relationship: <?in-line-formulae description="In-line Formulae" end="lead"?>X<SUB>2</SUB>O<SUB>3</SUB>:(n)YO<SUB>2</SUB><?in-line-formulae description="In-line Formulae" end="tail"?> wherein X is a trivalent element, Y is a tetravalent element and n is less than 60. The material has an average crystal size of the material is less than 0.1 micron and a Diffusion Parameter for mesitylene of at least 1000x10<SUP>-6 </SUP>sec<SUP>-1 </SUP>when measured at a temperature of 100° C. and a mesitylene pressure of 2 torr. |
