Isomerization and disproportionation of m-xylene over zeolite β
J Perez-Pariente, E Sastre, V Fornes, JA Martens… - Applied catalysis, 1991 - Elsevier
The isomerization and disproportionation of m-xylene has been performed over zeolite β
samples with Si/Al ratios in the range from 11 to 42. The selectivity for isomerization versus
disproportionation and the selectivities among the isomerization and disproportionation
products are contrasted with the micropore structures proposed for zeolite β. The
isomerization and disproportionation activity of zeolite β depend strongly on the aluminium
content, decreasing with increasing framework aluminium content. Maximum activity is found …
