A new model for comminution behavior of different coals in an impact crusher
(Taylor and Francis Inc., 2014)In this study, breakage behavior of three different coals in a laboratory impact crusher was investigated. The laboratory impact crusher carrying three rows of hammers is rotating at 2,840 rpm driven by a 1.1 kW motor. In ... -
A study on the effects of coal feed size and coal type on the performance of a laboratory jaw crusher
(Taylor and Francis, 2014)In this study, the effects at the three different coal size fractions on the five different characteristic coal samples depend on the performance of a crusher in the laboratory. Thus, a jaw crusher was investigated. Based ... -
A new binder in production of water-resistant briquettes from bituminous coals: Co-polymer binder
(Taylor and Francis Inc., 2016)Briquetting could be a solution to economic and environmental problems regarding fine coals. However, briquettes that are formed using molasses disintegrate in water and create problems. Providing water resistance to ... -
Mapping of an HCCI engine using negative valve overlap strategy
(Taylor and Francis Inc., 2020)In order to control combustion phasing and extend operation range of homogeneous charged compression ignition (HCCI) engines, several techniques such as controlling inlet air temperature and pressure, using alternative ... -
A numerical study on the effects of EGR and spark timing to combustion characteristics and NOx emission of a GDI engine
(Taylor and Francis Inc., 2016)EGR is one of the most significant strategies for reducing especially nitrogen oxides (NOx) emissions from internal combustion engines. The thermal efficiency of spark ignition engines is lower than compression ignition ... -
Decomposition of NaBH4 with self-regeneration of carbon-supported CoCl2 catalyst
(Taylor and Francis Inc., 2017)In this study, economically favorable CoCl2 catalysts at four different amounts were supported on activated carbon (AC) for NaBH4 dehydrogenation. Supported catalyst could achieve hydrogen release for 2,060 cycles, which ... -
The effect of TiO2 contained within a titanium silicalite (TS-1) catalyst and on the selective oxidation of ammonia
(Berkeley Electronic Press, 2013)The selective oxidation of ammonia to hydroxylamine using titaniumsilicalite-1 as a catalyst with an increasing content range of 1-2.5 wt% TiO2 was systematically investigated in a batch reactor. The hydroxylamine yielded ... -
Toward a universal method for preparing molecularly imprinted polymer nanoparticles with antibody-like affinity for proteins
(American Chemical Society, 2016)We describe a potentially universal, simple and cheap method to prepare water-compatible molecularly imprinted polymer nanoparticles (MIP-NPs) as synthetic antibodies against proteins. The strategy is based on a solid phase ... -
River water quality model verification through a GIS based software
(2009)Research and development attempts on water quality models created valuable resources in the sense of model calibration and verification techniques. Recognizing the current degree of pollution in rivers and the importance ... -
Osmotic and membrane distillation for the concentration of tomato juice: Effects on quality and safety characteristics
(Elsevier Ltd, 2015)The aim of this study was to evaluate the utilization of osmotic distillation, membrane distillation, and coupled operation of these systems as an alternative to the conventional thermal evaporation (CTE) technique for the ... -
Dephytinization of wheat and rice brans by hydrothermal autoclaving process and the evaluation of consequences for dietary fiber content, antioxidant activity and phenolics
