Nowadays, the application of fuels and lubricants produced from renewable feedstocks has come to the front because of serious environmental problems and ambiguity of crude oil supply. In this paper mesoporous Pt/AlSBA-15 catalysts with different platinum contents were investigated and it was found that catalysts having 0.5 wt. % platinum showed the best results in the production of gas oil and base oil fractions with high isoparaffin content from Fischer-Tropsch wax. The selectivity of the target product fractions was high, and based on these facts the selective isomerization of the FischerTropsch wax can be a new application area of the Pt/AlSBA-15 catalyst.
