“…Ezeldin et al 2015 [37] also studied the effect of x-ray radiation on diesel fuel at one hour, to improve the physico-chemical properties of diesel fuel, the diesel fuel produced from Khartoum refinery (Sudan). They found that the cetane number of diesels has been improved to 61 after exposure to x-ray radiation, as well as physico-chemical properties of sample after the expos process were improved to the limits assigned by ASTM and Khartoum refinery [37].…”

“…Diesel fuel improves based on gamma irradiation by degradation of the branched, cyclic, and aromatic compounds to form high linear chain hydrocarbons, which improve the cetane number [15]. In contrast, gasoline needs the opposite reaction because these compounds increase the octane number therefore improve all physicochemical characteristics [37,38].

Abstract. The effect of gamma irradiation on physico-chemical properties of petro-diesel fuel using different rate and absorbed doses has been studied. The diesel fuel samples were exposed to gamma radiation for 1.3 h using different absorbed doses: 3, 6, 10, and 15 kGy, with dose rates 2.27, 4.5, 7.4, and 11.15 kGy/h, respectively. Physico-chemical characteristics of diesel fuel were determined according to the standard test methods assigned by ASTM, characteristics are: cetane number, distillation recovery points, flash point, calorific value, density, and kinematic viscosity. The effect of gamma irradiation doses on organic compounds of diesel fuel was study using GC/MS technique. Experimental results show that the density, distillation, kinematic viscosity and flash point were decreased at absorbed doses 3, 6 and 15 kGy whereas increases at 10 kGy, corresponding with rate doses. Cetane number of diesel fuel increased after exposure to 3, 6, and 15 kGy but decreased at 10 kGy. These results can be attributed to the broken and formed bonds as a result of the high applied energy. The formed fragments at (10 kGy; 7.5 kGy/h) made a new compounds that have physical parameters affected negatively on the overall properties of diesel fuel. The formed fragments in diesel fuel after exposed to 3, 6, and 15 kGy (2.27, 4.5, and 11.15 kGy/h) have converted some of cyclic, aromatic, and branched organic compounds to linear hydrocarbons, which supported increasing of cetane number to 54. All characteristics have been improved within limits assigned by ASTM. Resumen. Se estudió el efecto de la irradiación gamma, a diferentes velocidades y dosis adsorbidas, sobre las propiedades físico-químicas del combustible de petróleo diésel. Las muestras de combustible diesel se expusieron a radiación gamma durante 1,3 h utilizando diferentes dosis absorbidas: 3, 6, 10 y 15 kGy, con tasas de dosis de 2,27, 4,5, 7,4 y 11,15 kGy / h, respectivamente. Las características físico-químicas del combustible diesel se determinaron de acuerdo con los métodos de prueba estándar ASTM, las características son: índice de cetano, puntos de recuperación de la destilación, punto de inflamación, poder calorífico, densidad y viscosidad cinemática. Se estudió el efecto de las dosis de irradiación gamma sobre los compuestos orgánicos del combustible diesel mediante la técnica GC / MS. Los resultados experimentales muestran que la densidad, la destilación, la viscosidad cinemática y el punto de inflamación disminuyeron en las dosis absorbidas de 3, 6 y 15 kGy mientras que aumentaron a 10 kGy. El número de cetanos en el combustible diesel aumentó después de la exposición a 3, 6 y 15 kGy, pero disminuyó a 10 kGy. Estos resultados se se taribuyen a enlaces rotos y formados como resultado de la alta energía aplicada. Los fragmentos formados a (10 kGy; 7,5 kGy / h) produjeron nuevos compuestos que tienen parámetros físicos que afectan negativamente a las propiedades generales del combustible diesel. Los fragmentos formados en el combustible diesel después de la exposición a 3, 6 y 15 kGy (2,27, 4,5 y 11,15 kGy / h) convirtieron algunos de los compuestos orgánicos cíclicos, aromáticos y ramificados en hidrocarburos lineales, lo que contribuyó al aumento del índice de cetano a 54. Todas las características se han mejorado dentro de los límites asignados por ASTM.

“…The properties of gasoline blends with propanol were less investigated, by far. The result of the addition of i-propanol to gasoline consisted in the decrease of the initial and final boiling point, and of the vapor pressure [18]. It is found that much of these studies have given little importance to the chemical composition of gasoline.…”

The properties of gasoline change as a result of blending with an alcohol. The aim of this paper is to report new experimental data on distillation curve and Reid vapor pressure of pseudo-binary blends of a catalytic reforming gasoline with ethanol, i-propanol and n-butanol, respectively. Gasoline blend with ethanol was used as reference for discussing properties of isopropanol and respectively, n-butanol blends with gasoline. The main conclusion is that alcohol addition to gasoline affects the relevant characteristics of the blend that influence engine operation. Gasoline+i-propanol blends have intermediate behavior between gasoline+ethanol and gasoline+n-butanol blends.
