Fabrication of ZnO/MgO nanoparticles for catalytic pyrolysis of Phoenix dactylifera seeds biomass

Abstract

In this study slow catalytic pyrolysis of Phoenix dactylifera(date palm seeds) was investigated in fixed bed reactor in the presence of doped ZnO/MgOnanoparticles. These NPs were prepared by using homogenous precipitation method. The effect of catalytic dosage of doped ZnO/MgO and ZSM-5 was studied on the conversion of biomass into pyrolysis products. By using doped ZnO/MgO the production of bio oil was increased, further increasing reduced bio oil yield. ZSM-5 caused slight increase in the yield of bio oil. The yields of bio char and syn-gas were also affected by variable dosage of catalyst.

“…Five sharp peaks can be seen in the Spectral range between 1000–1100 cm −1 . Metal oxides usually indicate absorption bands below 1000 cm −1 as result of interatomic vibrations [26]. The spectrum shows a board peak at 3412.6 cm −1 and a small peak at 2046.4 cm −1 indicating the presence of OH − stretching and bending modes related to the adsorbed water.…”
