摘要：In present work, the role of hydrogen in n-hexane isomerization was studied by poisoning the catalytic sites and prolonging the distance of hydrogen spillover. The results suggested the continuous consumption and regeneration of acid sites via hydrogen spillover was the core step in isomerization. In addition, the spillover of hydrogen would occur below 150 degrees C and the energy barrier of hydrogen spillover on the catalyst without surface water was less than 20.728 kJ/mol. Therefore, if the PtSZ catalyst has been almost dried, the subsequent reduction process could be eliminated. [GRAPHICS] .
