摘要: ABSTRACT We report on the basic properties of zeolite NaY and potassium supported (K/NaY) assessed by pyrrole-TPD MBOH transformation. Pyrrole-TPD revealed that impregnation with promoted additional adsorption sites for pyrrole compared to parent zeolite. For various loadings, adsorbed K/NaY decreased increased loading. Reduction in could be due hindering intrinsic (lattice oxygen), oxide occluding cavities restricting access pyrrole, or K2O reacting form nondesorbed pyrrolate anions. On transformation, almost completely suppressed acid while basicity
