Oxidative conversion of butane and pentane on superacid catalysts
Catalytic properties of AlBr3, AlBr3−CuCl2 and AlBr3−NiSO4 in liquid-phase conversion of butane and pentane have been examined. A possibility for the oxidative condensation has been revealed due to both the stoic...

Hydrocarbon conversion on ZSM-5 in the presence of N2O: relative reactivity
Conversions of methane, ethane, propane, benzene and hydrogen were studied on HZSM-5 at 418°C using binary mixtures R1:R2:N2O:He (where R1, R2 are substances under study). Relative reactivities were determined, a...
