Evaluation of the role of the pyrolysis temperature in straw biomass samples and characterization of the oils by GUMS
Ateş, Funda; Işıkdağ, Müjde Aslı (American Chemical Society, 2008)The aim of this study is to investigate the variation of thermal conversion of agricultural wastes in a fixed bed reactor with temperature and elucidating the chemical structure of oil products formed during the process. ... -
Fixed bed pyrolysis of Euphorbia rigida with different catalysts
Ateş, Funda; Pütün, Ayşe Eren; Pütün, Ersan (Pergamon-Elsevier Science LTD, 2005)Since Euphorbia rigida is a celluloid plant with low fat content, the oil yields of previous fixed bed pyrolysis studies were low. In order to increase the oil yield, biomass pyrolysis experiments were performed in a fixed ... -
Influence of temperature and alumina catalyst on pyrolysis of corncob
Ateş, Funda; Işıkdağ, Müjde Aslı (Elsevier Sci LTD, 2009)Corncob has been investigated as an alternative feedstock to obtain fuels and chemicals via pyrolysis in fixed-bed reactor. The influence of pyrolysis temperature in the range 300-800 degrees C as well as the catalyst ... -
Optimization of bio-oil production using response surface methodology and formation of polycyclic aromatic hydrocarbons (PAHs) at elevated pressures
Ateş, Funda; Erginel, Nihal (Elsevier Science BV, 2016)This paper aims at the optimization of bio-oil yield obtained from poplar sawdust pyrolysis. A response surface methodology was carried out to optimize the experimental conditions. The factors investigated were temperature, ... -
Pressurized pyrolysis of dried distillers grains with solubles and canola seed press cake in a fixed-bed reactor
Ateş, Funda; Miskolczi, Norbert; Sarıcaoğlu, Beyza (Elsevier Sci LTD, 2015)Pressurized pyrolysis of biomasses was carried in a fixed bed reactor to obtain gases, bio-oils and chars at elevated temperatures.
