Ja. Navio et al., CATALYTIC PROPERTIES OF ZRO2SIO2 - EFFECTS OF SULFATION IN THE CYCLOHEXENE ISOMERIZATION REACTION, Journal of catalysis, 161(2), 1996, pp. 605-613
Catalytic properties of ZrO2-SiO2 (14% molar) for cyclohexene conversi
on (skeletal isomerization and hydrogen transfer) have been studied. T
extural and morphological properties were correlated to explain cataly
tic behavior. XRD, DTA-TGA, N-2 adsorption, DRIFT, and acidity measure
ments by pyridine and dimethylpyridine chemisorption were used to char
acterize samples, The effect of the sulfation process upon surface str
ucture as well on catalytic activity/selectivity has also been studied
. It has been shown that catalytic activities are increased on sulfate
d samples, but at the same time products of the hydrogen transfer reac
tion seem to be increased too, lowering the selectivity of the reactio
n; isomerization always predominates, Sulfation transforms this compou
nd to a relatively selective isomerization catalyst exhibiting greater
catalytic activity. (C) 1996 Academic Press, Inc.
