Detonation propagation and detonation limits in gaseous ternary systems of methane, ethane, n-propane, and n-butane with oxygen and nitrogen have been studied in a 50-mm bore tube, at 1 bar.a and room temperature, after initiation by a denotating mixture of stoichiometric hydrogen and oxygen. Fuel-lean limit concentrations in each system are largely independent of increased diluent concentration up to mixtures with air, but fuel-rich limit concentrations vary and in the case of n-propane and n-butane appear dependent on energy release from condensation processes. For both dilutions, however, the results support once again the opinion that shock temperatures of at least 1200 K are a prerequisite for stable, viable detonation of aliphatic natural gas constituents confined in tubes with nitrogen and/or oxygen. On a relative scale, for mixtures with air, methane appeared least and ethane most detonable.

SHOCK TEMPERATURE AS A CRITERION FOR THE DETONABILITY OF LNG/LPG CONSTITUENTS MICHELS, HJ; RASHIDI, F (Elsevier BV, 1992-12-01) Detonation limit data obtained at ambient conditions for some aliphatic LNG/LPG constituents with oxygen and nitrogen (air) have been analyzed in search of a single critical parameter for detonation propagation. It was established that shock, rather than C-J reaction temperatures, provides a firm basis for marginal detonability prediction and that, furthermore, classical reaction mechanisms and relatively simple calculation methods can be used for their reliable evaluation. The result is used to formulate a...
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...
New observations of isolated ethanol droplet flames in microgravity conditions Park, Seul-Hyun; Choi, Seuk-Cheun; Choi, Mun Young; Yozgatlıgil, Ahmet (Informa UK Limited, 2008-01-01) Spherically symmetric ethanol droplet combustion experiments were performed to investigate the influence of initial droplet diameter, ambient pressure and inert substitution on the burning and sooting behaviors of ethanol droplet flames. Experiments were performed using the 2.2 sec reduced-gravity droptower facilities at the NASA Glenn Research Center. Noting the importance of transport characteristics of heat and species and their attendant effects on flame temperature and residence time on the sooting mec...
SCANNING ELECTRON-MICROSCOPY OF TREATED BITUMINOUS COALS HUAI, HY; GAINES, AF; FLINT, CD (Elsevier BV, 1992-11-01) 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 b...
Combustion characteristics of asphaltites Kök, Mustafa Verşan; Ceylan, Ezgi; Ozkiliç, Oke (Informa UK Limited, 2005-04-01) In this research, a laboratory work is performed to observe the combustion characteristics and reaction kinetic's of Silopi region asphaltites. A total of twelve experiments were performed with two different mesh sizes and under three different pressures. Product gas analyses were used to determine atomic H/C ratio, relative reaction rate, activation energy and Arrhenius constant for each asphaltite sample studied. The relative reaction rate vs. inverse temperature plots of Silopi asphaltite showed two main...
