Resumen:
The hydromerization"cracking of n"octane for obtaining light C4"C6 isoparaffins was studied using catalysts  based on H3PW12O40 (HPA).  The catalysts of HPA supported over zirconia and promoted with Pt are the most adequate for  performing the isomerization and cracking of long paraffins to yield high RON gasoline molecules, because they present higher values of Brönsted acidity.  The selectivity pattern of catalysts point to a simple mechanism of transformation in which n"C8 is isomerized to yield i"C8 that is subsequently broken mainly in middle positions.  Finally one part of the produced n"C4 is isomerized to i"C4.
