Bio-oil production by fast pyrolysis of olive residue: Effect of pyrolysis temperature and heating rate
Uzun, Başak Burcu; Pütün, Ayşe Eren; Pütün, Ersan (Norwegian University Sci Technol, 2005)In this study our aim is to reach high yields of bio-oil in a fixed bed tubular reactor at various pyrolysis temperatures, sweeping gas velocities, and heating rates. In these experiments, to improve heat and mass transfer, ... -
Biocrude from biomass: pyrolysis of cottonseed cake
Özbay Nurgül; Pütün, Ayşe Eren; Uzun, Başak Burcu; Pütün, Ersan (Pergamon-Elsevier Science LTD, 2001)Fixed-bed pyrolysis experiments have been conducted on a sample of cottonseed cake to determine the possibility of being a potential source of renewable fuels and chemicals feed-stocks, in two different reactors, namely a ... -
Co-pyrolysis characteristics and kinetics of plastic waste with biomass waste
Kılıç, M.; Pütün, Ayşe Eren; Pütün, Ersan (Nis University, 2011)In the present study, co-pyrolysis of plastic waste with biomass waste were carried out in a thermogravimetric analyzer heating from room temperature to 800 °C with a heating rate of 10 °C min-1 in the presence of nitrogen ... -
Co-pyrolysis of oil shale and biomass
Kılıç, M.; Poyraz, Z.; Pütün, Ayşe Eren; Pütün, E. (Nis University, 2011)In this study, co-pyrolytic behaviors of oil shale and Euphorbia rigida were investigated at different temperatures in a fixed bed reactor at 450, 500, and 550 °C with a heating rate of 10 °C min-1 in the presence of ... -
An energy crop for producing bio-fuel: Euphorbia rigida
Uzun, Başak Burcu; Pütün, Ayşe Eren; Apaydın, E; Pütün, E (Norwegian University Sci Technol, 2005)Biomass and energy crops are the renewable energy sources, which is often believed to have the highest potential to contribute to a future sustainable energy supply to world's energy. Bioenergy is expected to become one ... -
The Evaluation of Mesoporous Materials as Catalyst in Fast Pyrolysis of Wheat Straw
Ateş, Funda; Tophanecioğlu, Sibel; Pütün, Ayşe Eren (Taylor & Francis Inc, 2015)In this study, wheat straw was chosen as a biomass sample and the fast pyrolysis of this sample was carried out with or without catalyst at different conditions in a well-swept fixed-bed reactor. Experiments were carried ... -
Pyrolysis Kinetics and Thermal Decomposition Behavior of Polycarbonate - a Tga-Ftir Study
Apaydın Varol, Esin; Polat, Sevgi; Pütün, Ayşe Eren (Vinca Inst Nuclear Sci, 2014)This study covers the thermal degradation of polycarbonate by means of Thermogravimetric Analyzer coupled with Fourier transform infrared spectrometer (TGA-FTIR). Thermogravimetric analysis of polycarbonate was carried out ... -
Rice straw as a bio-oil source via pyrolysis and steam pyrolysis
Pütün, Ayşe Eren; Apaydın, Elif; Pütün, Ersan (Pergamon-Elsevier Science LTD, 2004)The pyrolysis of rice straw was studied to estimate the effect of pyrolysis conditions on product yields and bio-oil composition when the heating rate was 5 K/min. Pyrolysis temperature, particle size, sweeping gas flow ...
