“…In this study, SDS and APG1214 were selected for preparing the SDS and APG1214 solution, considering the economy, environmental protection, and secondary dust. − Materials Studio software was used to reveal the wetting mechanism of the SDS and APG1214 solution on bituminous coal, which can explain some phenomena and mechanisms on the atomic structure and microlevel, which cannot be observed in experiments. − The distribution of tail group C, head group S, and O in the waterSDS and APG1214bituminous coal system, the number of intermolecular hydrogen bonds, and the interaction energy of the water–SDS and APG1214–bituminous coal system and the water–bituminous coal system were obtained.

To solve the problem of poor dust wettability during coal mine dust treatment, sodium dodecyl sulfate (SDS) and alkyl glycoside (APG1214) were selected for compounding. An efficient, environmentally friendly, economical wetting agent was prepared. First, through molecular dynamics simulation studies, it was determined that the tail group C of SDS and APG1214 was adsorbed on the surface of bituminous coal, and the head groups S and O were adsorbed on the surface of water. The simulation result is found to be consistent with the surfactant solution dust removal theory, which proves the confidence of simulation. Then, by comparing the interaction of water–SDS and APG1214–bituminous coal and water–bituminous coal systems and the number of hydrogen bonds, the wetting mechanism of the SDS and APG1214 solution on bituminous coal was revealed. Finally, the surface tension, contact angle, and wetting time of different SDS and APG1214 solutions were determined by experiments and they decreased with decreasing mass fraction of SDS at the same concentration. The surface tension of the SDS and APG1214 solution and the number of micelles affected the wettability of bituminous coal. The optimal concentration of the SDS and APG1214 solution was 0.7%, and the optimal ratio was SDS/APG1214 = 1:3.

“…3). Figure 3 shows the increase in synthesis results from 75 o C to 90 o C. It is caused by the reaction speed, which is greatly influenced by the rise in reaction temperature, the pure vapor pressure of the component (P o sat), and the boiling point of the mixture of synthesized elements [20]. However, after the temperature exceeds 96 o C, a decrease in synthesis results occurs because after the temperature is above 90 o C, the operating conditions are above the boiling point of the component mixture.…”

Surfactants produced from oil and natural gas derivatives can cause environmental pollution because they produce waste that is difficult to degrade. So, it is necessary to develop surfactant production which does not pollute the environment, for example, Alkyl poly glucosides, here a new type of alkyl poly glucoside surfactant will be synthesized by reacting Tert-butyl Glucoside (TBG) with oleic acid to form Tert-butyl Oleil Glucoside (TBOG). The aim in this research is to determine the exact reaction kinetics model and the kinetics parameters of the Tert-butyl Glucoside (TBG) esterification reaction with oleic acid using p-TSA as catalyst and modification of the addition of organic co-solvent. The variables studied were the mole ratio (TBG: oleic acid), temperature, and % catalyst. From observations, the best conditions were obtained at a mole ratio of 1: 4, the temperature of 90 o C and 2% catalyst. The best yield obtained was 91.49%. Product quality was characterized by FTIR and GC-MS spectroscopy. The kinetics of esterification reaction of TBG with oleic acid using catalyst p-TSA and modification of the addition of organic co-solvent was carried out at 75, 90, 92 o C. The reaction kinetics parameters for the kinetics model with co-solvent are A1 o = 6,10 3 L / mol.s; A2 o = 1,3.10 1 L / mol.s;-Ea1 =-2.103,44 J / mol;-Ea2 =-1.446,63 J / mol. The reaction kinetics parameters for the kinetics model without the addition of co-solvent are A1 o = 3

“…21 The excellent reduction effect on the water surface energy urges surfactants more easily to form foam to trap dust. 22 Reports suggest that foams realize a dust removal efficiency of 87.9% and suppress the second fugitive dust. 23 The traditional WBF is prone to burst due to the combined action of Ostwald ripening, coalescence, and external environment, losing its dust catcher capacity.…”

The atmospheric dust has a great negative impact on the societal harmonious development that starves for an efficient dust suppressant. This paper proposes a novel AES/polyacrylamide strengthen foam (APSF) to improve the dust trapping effectiveness. The APSF structure property and dust suppression capacity are studied and evaluated through the molecular dynamics simulation and experimental tests. The results express that APSF exhibits the stronger structure stability, superior water retention, and slower drainage performance than the traditional water-based foam (WBF). APSF dynamic simulation is studied by the relative concentration, radial distribution function, head group orientation, and mean square displacement. Research shows that APSF introduces water to thicken the hydration layer. The interaction strength between water and surfactant head groups is enhanced by 22.62 and 31.37% in the first and second hydrated water shells. APSF improves the sodium fatty alcohol ether sulfate (AES) orientation and weakens the diffusion of water molecules, which favors the foam stability. APSF exerts a better wettability on the coal dust through the wet settlement and contact angle tests. The APSF liquid film thickness reduces to 58.05 from 64.80 μm that is 3.14 times of WBF according to the foam liquid film decay experiment. Fourier transform infrared (FTIR) spectroscopy analysis indicates that there is an evident reinforcement on the coal surface absorption peak intensity of hydroxyl-and oxygen-containing functional groups treated by APSF. FTIR results are further determined by energy-dispersion spectrum analysis.
