The interaction between diesel and surfactant Triton X-100 and their adsorption on coal surfaces with different degrees of oxidation

Abstract

The interaction between diesel and surfactant Triton X-100 and their adsorption on coal surfaces with different degrees of oxidation

Effect of saline water on the synergistic interaction between diesel and Triton X-100 in the flotation of oxidized coal

“…5, in both DI water and saline water, the adsorption density of C16 in presence of Triton X-100 was higher than that in absence of Triton X-100, suggesting that Triton X-100 was able to improve the adsorption of diesel on oxidized coal, regardless of water salinity. This may result from diesel emulsification by Triton X-100 which increased the contacts between diesel droplets and coal particles (Chang et al, 2019). Additionally, it is worth noting that the adsorption density of diesel in saline water was higher than that in DI water with or without Triton X-100, suggesting that saline water was able to promote diesel adsorption on oxidized coals, which was not influenced by the presence of Triton X-100.…”

“…Then, the concentration of hydrocarbons in hexane was analyzed by gas chromatography-flame ion detector (GC-FID). The measurement details have been reported elsewhere (Chang et al, 2019). Both DI water and saline water was used in the measurement of diesel adsorption density.…”

“…Cebeci (2002) reported that in the flotation of lignite coal, the adsorption of kerosene on coal surface was enhanced by emulsifier and surfactant, and coal flotation performance was significantly improved. In previous work (Chang et al, 2019), it was found that composite collector consisting of nonpolar collector and polar collector was able to improve oxidized coal flotation with polar collector targeting oxidized coal surface area and nonpolar collector targeting un-oxidized coal surface area.…”

Microscopic Diffusion Characteristics of Linear Alkylbenzene Sulfonates on the Surface of Anthracite: The Influence of Different Attachment Sites of Benzene Ring in the Backbone

“…Research on coal flotation and coal dust suppression relies on the basic theory of coal wettability [16,[21][22][23]. Existing experimental research has proved that diffusion characteristics of surfactants on a coal surface are an important factor affecting the wettability of coal [23][24][25][26][27][28]. However, the experimental method cannot explain the structure, dynamics, and energy characteristics of the molecular adsorption In the coal industry, surfactants have been widely used in co suppression [16][17][18][19][20].…”

Improving Coal Flotation by Gaseous Collector Pretreatment Method and its Potential Application in Preparing Coal Water Slurry

“…Flotation is an effective way to upgrade coal slime [7][8][9][10][11][12]. However, due to the high oxygencontaining functional groups and pores on the surface of LRC, the surface is highly hydrophilic and difficult to upgrade using conventional flotation method [13][14][15][16].…”
