“…Four main peaks (high intensity peaks) were shown in the FTIR. These were, 1) C–H stretching modes for the aromatic (3000 cm −1 ) and aliphatic (2950, 2925 and 2860 cm −1 ) groups, 2) C=C stretching of aromatics at 1600 cm −1 , 3) C=O stretching vibration (at 1725 cm −1 ) present in various aldehydes, carboxylic acid, esters, anhydrides, and ketones, and 4) –OH stretching modes (at 3300 and 3650 cm −1 ), and it arises from different carbon sources such as carboxylic acid and phenolic groups 30 . Based on the functional groups, four possible mechanisms can be provided for the adsorption of MB dye on the diesel soot.…”

The diesel soot (DS) coated non-woven fabric was studied for oil-water separation along with the adsorption of dyes, detergents, and pharmaceuticals. The DS coated non-woven fabric showed more than 95% separation efficiency and consistent repeatable performance during oil-water separation experiment. In addition to this, the DS coated non-woven fabric of 17.2 cm 2 area successfully adsorbed ~85%, 97%, and 100% methylene blue (MB) dye, ciprofloxacin, and detergent, respectively from their respective solutions within 30 min, which was not possible using uncoated non-woven fabric. The DS coated non-woven fabric was found to be hydrophobic with the contact angle of 140° which was almost invariant upto 60 °C. Hence, the DS coated non-woven fabric showed promising performance in the oil-water separation and adsorption applications.

“…The physical properties of the liquid fuel tend to control fuel spray characteristics, whereas the fuel composition determines the pathways of chemical reactions during combustion [22]. Besides the fuel sulfur content, fuel characteristics, such as the fuel density [23,24], viscosity [25,26], cetane number [27,28], and fuel contents of aromatic compounds [29], influence particle formation.…”

Effect of Alternative Liquid Fuels on the Exhaust Particle Size Distributions of a Medium-Speed Diesel Engine

et al. 2019

We mainly aimed to determine how alternative liquid fuels affect the exhaust particle size distributions (PSD) emitted by a medium-speed diesel engine. The selected alternative fuels included: circulation-origin marine gas oil (MGO), the 26/74 vol. % blend of renewable naphtha and baseline low-sulfur marine light fuel oil (LFO), and kerosene. PSDs were measured by means of an engine exhaust particle sizer from the raw exhaust of a four-cylinder, turbocharged, intercooled engine. During the measurements, the engine was loaded by an alternator, the maximum power output being set at 600 kW(e) at a speed of 1000 rpm. The partial loads of 450, 300, 150 and 60 kW(e) were also used for measurements. At each load, the PSDs had a distinct peak between 20 and 100 nm regardless of fuel. Relative to the other fuels, circulation-origin MGO emitted the lowest particle numbers at several loads despite having the highest viscosity and highest density. Compared to baseline LFO and kerosene, MGO and the blend of renewable naphtha and LFO were more beneficial in terms of total particle number (TPN). Irrespective of the load or fuel, the TPN consisted mainly of particles detected above the 23 nm size category.

“…Results illustrated that soot nanostructure had an increased carbonization degree resulting from larger fringe length, lower fringe tortuosity and smaller interlayer spacing of soot when H 2 O is doped. Alrefaai et al (Alrefaai et al, 2018) investigated the characteristics of soot in diesel flames doped with dicyclopentadiene. It was found that the addition of dicyclopentadiene caused the increase of the content of hydrogen, oxygen and aliphatic groups, the enhancement of the reactivity, and the diminishment of the content of aromatic groups for soot particles.…”

As a product generated from incomplete combustion, soot is harmful to people’s health and the environment. In recent decades, much attention has been paid to the control of soot generation in combustion systems. Efforts to reduce soot emissions depend on a basic understanding of the physical and chemical pathways from fuel to soot particles in flames. At the same time, flame synthesis method has become an alternative method for the preparation of carbon nanomaterials because of its advantages of low cost and mass production. Carbon-based materials can be synthesized within the sooting zones in flames. The research of soot formation mechanism in flames can provide support for the synthesis of carbon nanomaterials. In this paper, the effects of additives, temperature, and fuel type on soot formation characteristics and soot nanostructure in diffusion flames are reviewed. The deficiencies and prospects are put forward for future research.
