Scanning electron microscopy of particles of three bituminous coals (78.5% C, 81.7% C and 89.9% C d.a.f.) which had been treated with pyridine, methanol, bromine, air, sulfuric acid, ammonia and alkylating agents showed that the reagents produced significant changes in the morphology of the particles. The particles cracked and disintegrated in ways which appear to be characteristic of the disruption of hydrogen bonding, the volume and thermal changes accompanying local reactions and of the breakage of C-C bonds.

Characterization and kinetics of light crude oil combustion in the presence of metallic salts Kök, Mustafa Verşan (American Chemical Society (ACS), 2004-05-01) In this research, a reaction cell, thermogravimetry (TG), and differential thermal analysis (DTA) were used to characterize the light crude oil combustion and kinetics in the presence of copper(I) chloride (CuCl) and magnesium chloride (MgCl2·6H2O). In TG-DTA experiments with magnesium chloride, three reaction regions were identified, known as distillation, low-temperature oxidation (LTO), and high-temperature oxidation (HTO). In the case of copper(I) chloride, two main transitional stages are observed with...
NANOSTRUCTURE OF SOOT COLLECTED FROM ETHANOL DROPLET FLAMES IN MICROGRAVITY Park, Seul-Hyun; Choi, Mun Young; Yozgatlıgil, Ahmet (Informa UK Limited, 2009-01-01) The nanostructure of soot particles collected from spherically symmetric ethanol droplet flames were analyzed using a high resolution transmission electron microscopy (HRTEM). Nanostructure properties, including fringe length and curvature of carbon lamellae, were measured for soot particles collected in various inert environments. The sampling experiments were performed in the reduced gravity environments produced in the NASA 2.2 sec Droptower at the Glenn Research Center in Cleveland, Ohio. Microgravity d...
Thermal Analysis of Crude oil lignite mixtures by Differential Scanning Calorimetry Kök, Mustafa Verşan (Elsevier BV, 1994-04-01) Thermal characterization of lignite, crude oils and their 10 and 20% mixtures were investigated by differential scanning calorimetry (d.s.c.). The calorific value of the lignite increased in mixtures depending on the crude oil type. In pyrolysis runs, temperature ranges where distillation and visbreaking occur were identified for the crude oils studied. The effect of heating rate was also studied, and higher reaction temperatures and higher heat flow rates were observed at d.s.c. peak thermograms with incre...
ELECTROKINETICS OF OXIDIZED COAL SARIKAYA, M; OZBAYOGLU, G (Elsevier BV; 1990-01-01) Electrokinetic measurements were carried out in order to determine the properties of oxidized coal surfaces over a wide pH range both in the presence and absence of various metal ions and flotation collectors. It was found that polyvalent cations, such as Fe++, Fe+++ and Al+++ decreased the zeta potential to zero and then reversed the charge. In the presence of cationic collectors, the negative value of zeta potential of oxidized coal was driven positive, below 9.3 to 10.9 depending on the type and concentr...
DSC study on combustion and pyrolysis behaviors of Turkish crude oils Kök, Mustafa Verşan (Elsevier BV, 2013-12-01) This study focused on the investigation of non-isothermal thermal behavior and kinetics of Turkish crude oils under combustion and pyrolysis conditions using differential scanning calorimetry (DSC). On DSC combustion curves, two exothermic oxidation regions were detected known as low temperature (LTO) and high temperature oxidation (HTO). Again, two distinct reaction regions were revealed under pyrolysis conditions and DSC curves exhibited endothermic behavior for both the distillation and cracking regions....
