Hydroisomerization of long-chain paraffins: Mechanism and catalysts. Part II

A review of the literature on long-chain paraffin hydroisomerization catalysts is presented. Part I described paraffin hydroisomerization mechanisms and presented an analysis of data on the catalysts of hydroisomerization on zeolites of various types. Part II is devoted to catalysts based on structured mesoporous materials, partially reduced molybdenum oxides and oxycarbides, and mixtures of tungsten and zirconium oxides. Industrial catalysts that have found use in isodewaxing of diesel fuels and oils are described.
