► H-ZSM-5 was more active than H-Y in the transformation of FT naphtha at 450 °C. ► Detailed PIANIO analysis of the products allowed a fair estimate of the conversion. ► The transformation of the FT naphtha produces dry gas, LPG and coke. ► Products in the naphtha range were mainly naphthenics and aromatics.
