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.

This study covers the slow catalytic pyrolysis of Calotropis procera (Akh plant root) using biogenically synthesized NiO NPs. The synthesized particles were characterized by UV-Visible and FTIR spectrometry. Catalytic activity of the NiO NPs was examined via slow catalytic pyrolysis of Akh plant roots by monitoring temperature and catalyst effect on feedstock for the production of high yield bio-char, bio-oil and bio-gases. At 250°C low bio-oil and higher bio-char yield were obtained. However, at higher temperature inverse results were obtained whereby at optimum temperature of 300°C, the yield of bio-char, bio-oil and biogas 37, 36 and 27% was attained
