The catalysts g-alumina (GA, the reference catalyst) and Pt doped g-alumina (PGA-s) were synthesized using a simple sol-gel technique, in which at first preparation of porous base (GA), then
impregnation of platinum salt over the base and finally reduction of platinum in the surface of the
support were done. These catalysts prepared in different mole ratios of Pt:Al as 2:1, 1:1 and 1:2 are
named as PGA-1, PGA-2 and PGA-3 respectively. The isomerization of n-alkanes (n-hexane, nheptane and n-octane) were investigated over the synthesized catalysts. The 2-methyl pentane (2-
MP), 2,2-dimethyl pentane (2,2-DMP) and 2,3-dimethyl hexane (2,3-DMH) are the major products
of respective isomerization of n-hexane, n-heptane and n-octane, besides a small amount of other
branched isomers are also produced. The product distribution is comparable to that reported for Pt
based other catalysts. The optimal mole ratios of Pt:Al is 1:1 (PGA-2) gives quite good catalytic
activity for isomerization of n-alkane. Even through in reusability study, PGA-2 gives better performance than others. We have mainly focused on kinetic study, reaction mechanism behind
isomerization and calculated the order of reactions and activation energies of the isomerization
reactions in the present work.
