Modification of sooting tendency by magnetic effects

Prediction of Sooting Tendency for Hydrocarbon Liquids in Diffusion Flames

A theoretical method for predicting the smoke point of pure hydrocarbon liquids is presented. The method is based on a structural group contributions approach and does not require any experimental procedures or information of fuel properties, other than the molecular structure of the fuel molecules. The proposed correlation is presented in the form of a multivariable regression. The average dev...

Novel Micropyrolyis Index (MPI) to Estimate the Sooting Tendency of Fuels

A new fuel quality indicator called micropyrolysis index (MPI) is proposed for quantifying sooting tendencies of fuels in research laboratories. The MPI has been designed with the following characteristics: (i) oxygen independence, since sooting tendencies can change dramatically with varying oxygen concentration, (ii) reduced sample volume that can be utilized on a laboratory scale, (iii) impr...

Modification of CoFe2O4 Magnetic Nanoparticles by Dopamine and Ascorbic Acid as Anchors

CoFe2O4 magnetic nanoparticles were modified by dopamine (DA) and ascorbic acid (AA) as anchors. Separation of the DA and AA using CoFe2O4 magnetic nanoparticles have been studied by investigating the effects of pH, concentration of the DA and AA, amount of adsorbents, contact time, ionic strength and temperature. The mechanism of adsorption was also studied. The adsorption of DA and AA to the ...

Investigation of the transition from lightly sooting towards heavily sooting co-flow ethylene diffusion flames

Laminar, sooting, ethylene-fuelled, co-flow diffusion flames at atmospheric pressure have been studied experimentally and theoretically as a function of fuel dilution by inert nitrogen. The flames have been investigated experimentally using a combination of laser diagnostics and thermocouple-gas sampling probe measurements. Numerical simulations have been based on a fully coupled solution of th...
