Abstract

This work investigated the in situ catalytic pyrolysis of oil palm empty fruit bunch using CaO-impregnated zeolite (CaO/HZSM-5) catalyst. An optimum point was obtained via central composite rotatable design at reaction temperature of 567.10�C catalyst loading of 3.22 wt% and CaO loading of 1.25 wt% with an expected bio-oil yield of 35.31 wt%. Validation runs� experimental yield was 37.59 ? 1.74 wt% indicating reliability of the condition. The impregnated catalyst was characterized and CaO was observed to be successfully impregnated onto HZSM-5 with minor degradation on the catalyst structures. The bio-oil produced through catalytic pyrolysis had increased 16.102 wt% water content and also lower acid content by 8.02% and higher aromatic content by 18.86% as compared with non-catalytic pyrolysis possibly contributed by the combined catalytic effect of CaO/HZSM-5 catalyst via deoxygenation and neutralization reactions. Kinetic study using Coats-Redfern method indicated the decrement of activation energy and frequency factor by 2.14% and 49.17% respectively at reaction order of three with addition of CaO/HZSM-5 catalyst. Similar reductions in activation energies in presence of CaO/HZSM-5 catalyst was observed in model-free methods and the activation energies gradually increased with process conversion due to differences in valorization temperatures of hemicellulose (300�C) cellulose (340 and 390�C) and lignin (> 400�C). ?
