This application note describes the development of an innovative method for the confirmation of fire accelerants using the Agilent Capillary Trap Sampler (CTS), which is based on capillary column absorbing principles. CTS has the advantage of rapid sampling of airborne debris and toxic compounds within 1 minute. The study used 97 RON (Research Octane Number) octane gasoline as a standard, and c...

The fluorescence characteristics of norfloxacin (NFLX) were studied in reversed micelles which formed with sodium bis(2-ethylhexyl) sulfosuccinate (AOT)-water-octane. The influences of the environmental factors, such as the water content, AOT concentration and pH, on the fluorescence of NFLX were investigated. A novel spectrofluorimetric method for the direct determination of NFLX is proposed b...

The isomerization of n-hexane to produce mono- and di-branched isomers is an important process for octane enhancement gasoline. In a fixed bed reactor, packed with MFI catalyst, there synergy between mixture adsorption equilibrium intra-crystalline diffusion. This best exploited by operating the reactor in transient manner, whereby desired products consisting branched can be recovered from exit...

The tangent linear approximation (TLA) developed in Almohammadi et al. (Combust. Flame 230, 111426) is extended to estimate the sensitivity of ignition delay time with respect species enthalpies and entropies. proposed method relies on integrating linearized system equations governing evolution state vector’s partial derivatives variations thermodynamic parameters. estimated through a temperatu...

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

The quality of motor fuels is more and strictly controlled in connection with many factors - users are particularly interested the anti-knock resistance automotive gasolines, quantitatively expressed by value research octane number (RON). paper presents FTIR spectrometry conjunction chemometry as an alternative method to standardized determination gasoline a according ?SN EN ISO 5164. An FTIR-P...
