摘要:
A synthetic porous cystalline material has the structure of ZSM-5 and a composition involving the molar relationship: X2O3:(n)YO2, wherein X is a trivalent element; Y is a tetravalent element; and n is less than 25, and wherein the slope of the nitrogen sorption isotherm of the material at a partial pressure of nitrogen of 0,4 to 0,7 and a temperature 77 °K is greater than 30. The material has a mesoporous surface area (MSA) greater than 45 m2/g and is useful as a catalyst in the liquid phase isomerization of xylene.
