Bio-oil from rice straw is produced by pyrolysis with and without solid acid catalysts. Solid acid catalysts used in rice straw pyrolysis synthesis were the diatomite acidified by an ‘atomic implantation method’ and nano-sized porous Al-SBA1SBA: Santa Barbara Amorphous type mesoporous silica.-15. Catalysts were characterized by a field emission-scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), x-ray diffraction (XRD), infrared spectroscopy (IR), N<sub>2</sub> adsorption/desorption, differential thermal analysis/thermogravimetric analysis (DTA/TGA) and NH<sub>3</sub> temperature programmed desorption (NH<sub>3</sub>-TPD). The obtained results revealed that a similar bio-oil yield (liquid product) of 44–48% can be reached by pyrolysis in the presence of solid acid catalysts at 450 °C compared to that of pyrolysis without catalyst at 550 °C. Moreover, a low yield of gas product was observed. These results show significant potential applications of solid acid catalysts for the improvement of bio-oil yield in the pyrolysis of rice straw.
