Influence of metal doping on the coke formation of a novel hierarchical HZSM-5 zeolite catalyst in the conversion of 1-propanol to fuel blendstock.

ABSTRACT: In this work, the effect of Ni doping on coke formation and the activity of a novel hierarchical HZSM-5 zeolite catalyst in the conversion of 1-propanol to fuel blends was investigated. The catalysts, which were hydrothermally synthesised and modified with 0.5 wt% Ni, were characterised using different techniques (XRD, FTIR, SEM, PSD, N₂ adsorption, NH₃-TPD, TGA-DTA) and tested at 350-400 °C and, WHSV of 7 and 12 h^-1 for the conversion of 1-propanol into fuel blendstocks. The catalyst characterisation results confirmed the successful synthesis of hierarchical HZSM-5 and the incorporation of nickel. The catalytic results showed that both catalysts exhibited >98% 1-propanol conversion with considerable selectivity (>80%) for jet fuel and (>50%) gasoline blend
