The internal convective heat transfer characteristics of n-decane at supercritical pressure in a vertical square tube with a hydraulic diameter of 1.8 mm were experimentally investigated. The external wall temperatures of the square tube were measured with welded thermocouples whereas the intern...
In this work, the experimental measurements for liquid densities of n-decane and m-xylene binary mixtures were performed over the entire composition range with a high-pressure vibrating-tube densimeter. The range of temperatures for the present measurements was from 293.15 K to 363.15 K and the ...
Acute central nervous system (CNS) depression is the most sensitive toxicological effect associated with aliphatic hydrocarbon exposure. No observed effect levels for the CNS effects of aliphatic constituents decrease with increasing carbon number to C10 (Lammers et al., 2011; McKee et al., 2011...
Melting and crystallization of n-decane embedded into porous glass with the mean pore size of about 6.4 nm were studied using acoustic and DSC methods. Smearing of the phase transitions, decrease of melting and freezing temperatures, pronounced hysteresis between melting and crystallization were...
In this work, the liquid densities of n-decane/o-xylene mixtures were measured at four different component proportions, the mole fractions of n-decane are 0.2001, 0.4065, 0.5835, and 0.8041, respectively. The measurements were performed based on the high-pressure vibrating-tube densimeter, and t...
The location of n-decane molecules within the model biological membrane consisting of dioleoyl-phosphocholine (DOPC) bilayers has been investigated via small angle neutron diffraction (SAND) method and molecular dynamics (MD) simulations. Diffraction patterns of the samples containing varied amo...
In the last years, the phase behaviour of multi-component hydrocarbon systems in shale reservoirs has received significant attention. The main complexities in modelling the phase behaviour is the confinement. It is presented in this work, the results obtained by molecular dynamics simulation in ...
2-Methoxyacetic and 2-ethoxyacetic acids are well known toxic metabolites of 2-alkoxyethanols. The use of 2-alkoxyethanols is now restricted, and the regulations have forced manufacturers to find substitutive solvents, 2-(2-alkoxyethoxy)ethanols. 2-(2-Alkoxyethoxy)ethanols resemble 2-alkoxyethan...
The molecular structures of hydrocarbon fuels are known to have a substantial impact on their combustion properties. However, the relationship between the fuel structure and thermal decomposition intermediate products, which determine the global combustion behaviors, is not as well known. In thi...
Ethanol is a promising renewable fuel for spark ignition engine and it can be blended with gasoline in the full range from pure gasoline to 100% ethanol. The objective of this study is to investigate the influence of ethanol content on the research octane number (RON) of a gasoline surrogate. A ...
Given the demand for clean gasoline with ultralow sulfur and olefin contents, reduced olefin content, which inevitably results in a large octane number loss, is urgently needed. The key to finding a solution for octane number loss is to identify the relationship between olefin hydrogenation and ...
This work describes the first documented case of an effect defined herein as “octane hyperboosting” by an oxygenated fuel compound, 3-methyl-2-buten-1-ol (prenol). Octane hyperboosting is characterized by the Research Octane Number (RON) of a mixture (e.g. an oxygenate biofuel blended into gas...
This paper studies the oxidation of n-heptane, iso-octane, ethanol and their mixtures in a pressurized flow reactor, with a focus on the potential relation between the fuels oxidation reactivity and their octane ratings. The flow reactor experiments are conducted at 550–900 K, 10 bar and an equ...
The standard method for measuring the octane number of fuels requires large sample volumes ( ∼ 1L) and access to a Cooperative Fuel Research (CFR) engine. This method reliably quantifies the knock resistance of fuels in spark ignition engines, however the large sample volume requirement prevent...
Excess enthalpies for the two binary systems, 1-nonene-n-nonane and 1-hexanol-2-hexyn-1-ol, and the two ternary systems, n-nonane-1-hexanol-n-nonane and 1-hexanol-2-hexyn-1-ol-n-nonane, at 298.15 K have been determined with a Calvet-type microcalorimeter. The experimental results of the binary s...
The conversion of 4-vinyl substituted β-lactams into 4-vinyl substituted 1-azetines and their subsequent reaction with diphenylcyclopropenone (DPP) results in the formation of a highly functionalised 7-azabicyclo[4.2.1]nonene. This heterocyclic system is an isomer of the homotropane (9-azabicyc...
The density and viscosity data of two biodiesel components methyl dodecanoate and ethyl dodecanoate over the temperature range from (302–354) K and at pressures up to 15.2 MPa were reported. Experimental results show that the densities and viscosities of methyl dodecanoate and ethyl dodecanoate...
The inhibitive effect of the hexamethylenediamine tetra(methylene phosphonic acid) (HMDTMPA) on the corrosion of carbon steel in 1.0 M HCl solution has been investigated by weight loss measurement, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The pres...
A new aqueous alumina gelcasting system using hexamethylenediamine (HMDA) and paraformaldehyde monomers has been studied. The 500 vol% aqueous alumina slurries ‘A’ and ‘B’ containing paraformaldehyde and HMDA, respectively, undergo gelation after thorough mixing of the two due to the polymer...
The surface of chlorinated and fluorinated nanodiamond obtained by detonation synthesis was modified with ethylenediamine and hexamethylenediamine. Nanodiamonds with grafted diamines were found to manifest photoluminescence in Raman spectra; the occurrence and intensity of luminescence depended ...
