“…On the other hand, zeolite is aluminosilicate material which consists of a tetrahedral silicate and aluminate framework 67 . Zeolite and other clays are naturally abundant in Indonesia and very useful for adsorbent and catalyst materials 68–70 . Similar to alumina, zeolite material also has Bronsted and Lewis acid sites for organosulfur compounds adsorption.…”

Currently, crude oil still remains an irreplaceable energy source for chemical industrial processes, transportation systems, electricity, and other human activities. However, crude oil contains sulfur elements as the major impurities in the form of aliphatic and aromatic organosulfur compounds. During the combustion of fuel, these organosulfur compounds are converted to harmful SOx gases; thus, many countries strictly limit the maximum sulfur content in the fuels. To fulfill the government regulation, refineries are trying to decrease the maximum sulfur content in crude oil through several desulfurization technologies, such as hydrodesulfurization, adsorption, oxidative‐desulfurization, alkylation, and biodesulfurization. Each desulfurization technology has its own advantages and disadvantages. In this review article, we aimed to briefly summarize the progress in the developing science and technology of each desulfurization process of crude oil. Several fields in the desulfurization process are still facing challenges to create better designs and development for a safer future of the world.

“…The surfactant acts stabilizer of nanoparticles 17 . It was caused by the hydroxyls from the hydrolyzed HDTMS decrease the free energy of Gibbs on the surface of the Nylon, so the surfactant can work optimally 18 . Sample Ny3 also modified by silver nanoparticles and HDTMS too, but silver nanoparticles were impregnated first and continued by the adding of HDTMS compound.…”

Modification of Nylon fabrics with HDTMS compound and silver nanoparticles which prepared via bio-reduction method using banana peel extract (Musa paradisiaca Linn.) has been conducted in this research. That modification can increase the quality of Nylon fabrics so they have antibacterial and self-cleaning properties. The types of Nylon fabrics in this research are Nylon fabric (Ny0), Nylon-Ag (Ny1), Nylon-HDTMS (Ny2), Nylon-Ag-HDTMS (Ny3), and Nylon-HDTMS-Ag (Ny4). The silver nanoparticles were characterized by using spectrophotometry of UltraViolet-Visible. Antibacterial activity against gram-positive and gram-negative bacteria was analyzed by measuring the clear zone around the sample. While the contact angle test was performed by the sessile drop method. Silver nanoparticles have a maximum peak at the wavelength of 440.50 nm. Nylon-Ag shows the highest antibacterial activity against E.coli and S. aureus. The inhibition zone of Nylon-Ag at 54 hours of incubation time is 97 times higher than the inhibition zone of Nylon without modification at 24 hours of incubation against E.coli. Likewise, with the inhibition capacity of Nylon-Ag in inhibiting the growth of S. aureus, Nylon-Ag has antibacterial activity at 72 hours incubation time of 85 times higher than Nylon at 48 and 72 hours incubation. However, Nylon-HDTMS-Ag has the greatest contact angle, that was 110.63 o

“…Researchers are putting in the effort to modify the unsaturated fatty acids to overcome the limitation of the plant-based biolubricant. Among the unsaturated fatty acids, oleic acid is the simplest and thus it is widely studied as a model compound [13][14][15][16][17]. In 2017, Kurniawan et al modified oleic acid through esterification, hydroxylation, and ketalization reactions to produce dioxaspiro compounds [13].…”

In the present work, the stability of six biolubricant compounds, i.e. Acetal, Ketal, D[4.4], D[4.5], Cyclic-6, and Cyclic-7, was evaluated both theoretically and experimentally. These compounds were prepared from oleic acid through hydroxylation and esterification reactions. The computational study of the compounds was conducted by using the Density Functional Theory (DFT) method at B3LYP level of theory and 6-31 G (d,p) basis set. The theoretical stability was reflected from the internal energy value of the hydrolysis reaction of the biolubricant compounds to form the 9,10-dihydroxystearic acid. The order of stability is given as follows: Cyclic-6 (-3.458 kJ/mol) > Acetal (-3.446 kJ/mol) > Cyclic-7 (-3.364 kJ/mol) > D[4.5] (-3.343 kJ/mol) > D[4.4] (-3.261 kJ/mol) > Ketal (-3.058 kJ/mol). On the other hand, the experimental stability of the biolubricant compounds was measured using the American Society for Testing and Material (ASTM) standard method for total acid number (TAN) and total base number (TBN). It was found that the Cyclic-6 derivative yielded the lowest TAN (1.37 mg KOH/g) and TBN (3.53 mg KOH/g) values compared to the other biolubricant compounds. Meanwhile, the Cyclic-6 also showed the lowest internal energy value (-3.458 kJ/mol) from the computational study due to the high stability of six-membered ring. These results reveal that the experimental TAN and TBN values could be predicted from the theoretical internal energy value, i.e. TAN (mg KOH/g) = 35.183 (DE) – 123.02 (R2 = 0.9226) and TBN (mg KOH/g) = 105.71 (DE) – 369.72 (R2 = 0.8946), which is remarkable.
