Isomerization and hydrocracking of n-decane over Pt/MCM-41∥MgAPO-n composite catalysts

摘要

The hydroconversion of n-decane has been investigated over Pt/MCM-41∥MgAPO-n (n = 5, 11) composite catalysts. A high selectivity for n-decane isomerization has been observed over a 50 : 50 physical mixture of 1.0 Pt/MCM-41 with MgAPO-11, while hydrocracking is dominant over the catalysts composed of Pt/MCM-41 and MgAPO-5. The high isomer selectivity of the Pt/MCM-41∥MgAPO-11 catalyst is explained in terms of shape selectivity.
