Jm. Campelo et al., COMPARISON OF THE ACTIVITY AND SELECTIVITY OF PT SAPO-5 AND PT/SAPO-11 IN N-HEXANE AND N-HEPTANE HYDROCONVERSION/, Applied catalysis. A, General, 152(1), 1997, pp. 53-62
n-Hexane and n-heptane isomerization was studied over a series of bi-f
unctional Pt/SAPO-5 and Pt/SAPO-11 catalysts (0.5 wt% Pt), by using a
micro-catalytic pulse reactor. Results indicated that catalyst activit
ies are directly influenced by acidity (determined by pyridine and 2,6
-dimethylpyridine adsorption). Best selectivities for branched hexane
isomers are achieved with Pt/SAPO-5 whereas isomerization of n-heptane
is higher on Pt/SAPO-11 than on Pt/SAPO-5 catalysts.
