摘要：

The hydroisomerization-hydrocracking of nC(5)-nC(7) is studied with a 12MR unidirectional zeolite (ITQ-4). Selectivity and kinetic parameters indicate that differences in pore topology are more important than acidity for determining isomerization selectivity. The adsorption of the paraffins is determined by van der Waals interactions. (C) 2001 Elsevier Science B.V. All rights reserved.
