Interrelationships between the bond grindability with physicomechanical and chemical properties of coals
(Taylor and Francis, 2013)In this research, different techniques for the estimation of Bond grindability (Gbg) values of coals are studied. Data from ten sub-bituminous coals from Turkey are used by featuring physicomechanical (ISI, Is, and FD) and ... -
Prediction of the bond grindability index from the sink-float test data of coals
(Taylor and Francis, 2013)In this study, a relation for calculating the Bond grindability by the sink-float test data of coals was studied. Primarily, sink-float tests for three coal samples were made. Secondly, the cumulative weight and ash content ... -
Application of statistical process control for coal particle size
(Taylor and Francis, 2013)In this article, variations in particle sizes (F50 and P 50) obtained from feeding and ground coals in a vertical roller mill of AS Cement Factory (Turkey) were investigated using control charts and process capability ... -
The use of co-polymer flocculants for the elimination of the environmental effects of wastewater of a coal washer and design of a thickener for supplies of fresh water
(Taylor and Francis, 2013)A washing plant belonging to Özberil Mining Co. (Denizli/Turkey) has a 50 t/h of capacity and coal was washed with heavy media separation to increase its quality. Wastewaters of coal tailing streams of the washing plant ... -
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 ... -
