“…One of the most studied reactions for the normal C 5 –C 6 isomerization is the one using platinum supported on tungstated zirconia; − in particular, the n -hexane isomerization over this type of catalyst mainly produces 2-methylpentane (2-MP), 3-methylpentane (3-MP), 2,3-dimethylbutane (2,3-DMB), and 2,2-dimethylbutane (2,2-DMB) as well as some cracking products, where the biramified products exhibit the higher octane number. In general, the high activity and selectivity of the aforementioned catalyst depend not only on the composition of its materials but also on its various synthesis methodologies thus making the development and testing of this type of catalysts, to some extent, an inefficient and time-consuming process.…”
