Pitch based carbon fiber production
(Gazi University, Fac Engineering Architecture, 2018)
Carbon fiber, which has unique physical, chemical and biological properties, is a versatile material in fiber form composed of carbon atoms arranged in hexagonal structure. In the industrial production of carbon fibers, ...
Synthesis and Characterization of Supported and Non-Supported Iron-Incorporated Catalysts
(Gazi University, Fac Engineering Architecture, 2009)
In the content of this study, silica supported Fe-MCM-48 catalysts were produced using direct hydrothermal synthesis (Fe-MCM-48-1) and wet-impregnation (Fe-MCM-48-2) methods and an unsupported Fe-Mo-O catalyst was produced ...
Extraction Parameters and Analysis of Apricot Kernel Oil
(Asian Journal Of Chemistry, 2012)
Apricot kernel is an alternative raw material for fixed oil, which is used in food, pharmaceutical and cosmetic industries. It can be utilized I in place of almond oil because of similarities in fatty acid compositions. ...
