Characterization of bio-oils synthesized by pyrolysis from cistus ladaniferus transformed into biofuel and biodiesel used as an alternative green energy

The valorization of biomasses as a source of second generation biofuels is one of the future projects. The valorization, of seeds and shells of cistus ladaniferus as a source of biofuel by the thermal way, pyrolysis in fixed bed under the optimal conditions of temperature and heating speed present very encouraging results. The characterization of the liquid obtained by different analytical methods such as XPS, Elemental Analysis, FTIR, enriches the study. The calorific values of the two bio-oils of seeds and their shells obtained by pyrolysis at 450°C with a heating rate of 21°C min−1 and 40°C min−1 are of the order of 37.05 and 37.93 respectively. This work consisted in valorizing one of the forest rejects, in this case the seeds of cistus ladaniferus which are shrubs generally distributed in the Mediterranean ecosystem, by transforming its oil into biofuel (biodiesel). The fixed bed pyrolysis of these rejects also has the advantage of having a low environmental impact in terms of greenhouse gas emissions.
