Pentane transformation over SiO2(87%) - Al2O3/BCl3 superacid was studied. It was found that Brönsted superacid centres formed in the reaction between the carrier and BCl3 vapours are active in n-pentane low temperature transformation. Pentane is converted over them into carbenium ion (through intermediate carbonium ion), which either undergoes isomerization to form 2-methylbutane or reacts with a second molecule of the reactant forming 2-methylpropane and a longer surface carbenium ion. The latter acts as a secondary active centre for 2-methylpropane formation and also undergoes further transformation leading finally to coke.
