Kinetics of the Hydration of Ethylene Oxide in the Presence of Heterogeneous Catalyst
(American Chemical Society, 2009)
Kinetic data on the hydration of ethylene oxide was obtained from both uncatalyzed and heterogeneously catalyzed reactions using a pressurized batch reactor. Amberjet 4200/HCO(3)(-) was used as the heterogeneous catalyst, ...
Reaction kinetics of the catalytic esterification of acrylic acid with propylene glycol
(Elsevier Science BV, 2009)
The kinetics of esterification of acrylic acid with propylene glycol has been studied in the presence of Amberlyst-15 as a heterogeneous catalyst. The reaction was realized in a batch reactor at different temperatures and ...
Influence of temperature and alumina catalyst on pyrolysis of corncob
(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 ...
Evaluation of the role of the pyrolysis temperature in straw biomass samples and characterization of the oils by GUMS
(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. ...
Obtaining 2-octanol, 2-octanone, and sebacic acid from castor oil by microwave-induced alkali fusion
(American Chemical Society, 2008)
In this study, the effect of microwave irradiation on alkali fusion of castor oil was investigated using different NaOH/oil ratios (8:15, 12:15, and 14:15), reaction temperatures (473, 493, 503, 513, and 523 K), and reaction ...
Microwave assisted transesterification of rapeseed oil
(Elsevier Sci LTD, 2008)
Rapeseed is one of the important vegetable oil sources for biodiesel production due to its high oil content (around 40%). In this study rapeseed oil was converted to biodiesel by transesterification using microwave heating. ...
Chemical composition and oxidative stability of flax, safflower and poppy seed and seed oils
(Elsevier Sci LTD, 2008)
Three seeds of Turkish origin, flax, poppy and safflower were analyzed for their proximate, fatty acids, tocols (tocopherols and tocotrienols) and total phenolic composition, and oxidative stability of their oil. The major ...
Study of polyphenol content in the seeds of red grape (Vitis vinifera L.) varieties cultivated in Turkey and their antiradical activity
(Elsevier Sci LTD, 2008)
The polyphenolic content and antioxidant capacity in the seeds of 11 red grape varieties (five international and six native) widely cultivated in Turkey were investigated. Total phenolic, total flavanol and total polymeric ...
Optimization of parametric performance of a PEMFC
(Pergamon-Elsevier Science LTD, 2007)
In this study, the Taguchi method was applied to determine optimum working conditions in obtaining maximum power density of a PEMFC. Performance measure analysis was also followed by performing a variance analysis, in order ...
$Ca(OH)_2$ süspansiyonları ile $SO_2$ gideriminde bazı katkı maddelerinin etkisi
