Adsorption of Cr(VI) onto cross-linked chitosan-almond shell biochars: equilibrium, kinetic, and thermodynamic studies
Altun, Türkan; Ecevit, Hüseyin; Kar, Yakup; Çiftçi, Birsen (Springer, 2021)In this study, to remove Cr(VI) from the solution environment by adsorption, the almond shell was pyrolyzed at 400 and 500 degrees C and turned into biochar (ASC400 and ASC500) and composite adsorbents were obtained by ... -
Application of blast furnace slag as a catalyst for catalytic cracking of used frying sunflower oil
Kar, Yakup; Gürbüz, Zafer (Sage Publications, 2016)For catalyst performance assessment of blast furnace slag as a low-cost catalyst, the cracking runs of frying sunflower oil were carried out in the presence of two different catalysts (blast furnace slag and calcium oxide) ... -
Biochar Produced from Co-Pyrolysis of Olive Pomace & Crude Oil as an Adsorbent for Cr (VI) Removal from Aqueous Solutions
Almezgagi, Maha; Kaya, Gülcihan Güzel; Kar, Yakup; Devci, Hüseyin (Iranian Institute of Research and Development in Chemical Industries, 2022)This study investigated aqueous solution treatment to remove Cr (VI) using a biochar-based adsorbent. Olive pomace and crude oil were used to synthesize the biochar adsorbent via co-pyrolysis for the first time. The biochar ... -
Catalytic cracking of pyrolytic oil by using bentonite clay for green liquid hydrocarbon fuels production
Kar, Yakup (Elsevier, 2018)The pyrolysis of almond shell as a biomass feedstock was performed in order to obtain a bio-based feedstock for bio-refineries in a fixed-bed reactor under inert atmosphere (occurred by N-2 gas) at certain experimental ... -
Characterization of light diesel fraction obtained from upgraded heavy oil
Kar, Yakup; Şenel-Göksu, Dilek; Yalman, Yusuf (Egyptian Petroleum Research Institute, 2018)In this study, the role of a low-cost catalyst (activated molasses soil) over the hydrocarbon distribution of the light diesel (or distillate) fraction of the pre-upgraded heavy crude oil (Bati Raman) was examined in detail. ... -
Improvement of heavy crude oil via catalytic cracking process for refining into valuable blending stocks
Göksu, Dilek Şenel; Kar, Yakup (Taylor and Francis Inc., 2018)In this study, it was aimed to obtain the conversion of the heavy crude oil with 12.2 degrees API gravity into the liquid fuel-like condensate fractions having different boiling points of gasoline (initial boiling point-180), ... -
Liquid fuels from used transformer oil by catalytic cracking using bentonite catalyst
Kar, Yakup; Bozkurt, Gamze; Yalman, Yusuf (John Wiley and Sons, 2018)In this study, the main target was to obtain the liquid fuel-like product from the catalytic cracking of the used transformer oil over bentonite as a low-cost catalyst. For this aim, a series of cracking runs were performed ... -
Pyrolysis of waste pomegranate peels for bio-oil production
Kar, Yakup (Taylor & Francis, 2018)In order to obtain bio-oil from the pomegranate peel which is a by-product of juice production process, the dried pomegranate peel was pyrolyzed at a heating rate of 10 degrees C/min and different temperatures between 400 ... -
Removal of Cr(VI) from aqueous solution by pyrolytic charcoals
Altun, Türkan; Kar, Yakup (Editorial Board of New Carbon Materials, 2016)Bio-chars produced by the pyrolysis of walnut shells at 450? (BC450) and theco-pyrolysis of walnut shells and 20 wt% tar sand (BCTS20)at the same temperature, were investigated as potential adsorbents for the removal of ...
