A biological approach that can replace the use of chemical coagulants hazardous to human health is an efficient solution in treating oily wastewater. However, bio- coagulants have a time limit that can affect their effectiveness in treating oily wastewater. Thus, this paper presents research for the aging effect of bio-coagulant for treating oily wastewater. In this study, G-Treat was used as the bio-coagulant, which was produced from chitosan powder, acetic acid, and deionized water. The experimental procedure started by filling 500 mL of oily wastewater into a beaker. Next, 10 wt. % of G- Treat was added into the beaker for the jar test, which was mixed for 30 min at 150 rpm, followed by 2 h settling time. Then, the mixture was separated using filter paper. The analysis of oily wastewater characteristics was conducted using five types of analyses, which are pH, chemical oxygen demand (COD), biological oxygen demand (BOD), total sus- pended solids (TSS), and oil and grease (O&G) under the parameters of days (0–7 days), weeks (0–6 weeks), and months (0–3 months). From the result, the best performance of G-Treat was achieved at the optimum parameters during week 2, with 33.16%, 65.75%, 35.73%, 28.58%, and 0% removal of pH, COD, BOD, TSS, and O&G, respectively. In conclusion, the studied bio-coagulant demonstrated higher removal of pH, COD, BOD, TSS, and O&G at optimum parameters, and eventually, the level of effectiveness will drop.","PeriodicalId":235976,"journal":{"name":"Journal of Chemical Engineering and Industrial Biotechnology","volume":" 53","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139138056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diffusion of solute in solvent is key to natural gas purification. In this study, molecular dynamics (MD) simulations of the diffusion of carbon dioxide in heptane at different temperatures and pressures were performed to simulate the conditions of industrial purification process. The diffusion coefficients were measured in two different configurations; pure solvent and binary solute-solvent systems. The diffusion coefficients of the binary system were observed to be in the order of 10-9 m2/s. An increased temperature was observed to increase the diffusion coefficient of the carbon dioxide in heptane while an increase in pressure reduced the value of the diffusion coefficient. The diffusion coefficient was also observed to follow an Arrhenius-type relationship with respect to temperature. The activation energy of the system increased from 9.228 kJ/mol to 11.139 kJ/mol with pressure increase. A linear relationship was detected between the diffusion coefficient and the viscosity of the system and an increased viscosity of the system results in a decreased diffusion coefficient. The results of the research showed that carbon dioxide behavior in heptane offers the theoretical backing for the development of a new natural gas desulphurization solvent.","PeriodicalId":235976,"journal":{"name":"Journal of Chemical Engineering and Industrial Biotechnology","volume":" 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139138801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polylactic acid (PLA), a completely biodegradable polymer, has gained popularity for its biocompatibility, biodegradability, mechanical strength, and ease of processing. To overcome its toughness and thermal stability limitations, PLA has been blended with commercial polymers, such as rubber. Furthermore, the incorporation of recycled tire waste into PLA has demonstrated the potential to enhance its durability and strength. Joncryl® ADR is used as a chain extender and reactive compatibilizer to enhance the chemical interactions in the binary blend. The samples were prepared using a twin-screw extruder with the temperature between 150 and 190 ºC and 60 rpm of screw speed. These blends are then analyzed using a range of characterization techniques, including Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), scanning electron microscopy (SEM), tensile testing, and notched Izod impact testing.

The rubber seed oil (RSO) and waste cooking oil (WCO)-based biodiesel were prepared using a transesterification method in the presence of a heterogeneous catalyst. Several formulations were derived from two types of biodiesels (RSO and WCO) and tested according to the ASTM D6751 specification for acid value, free fatty acid (FFA), kinematic viscosity, pour point, cloud point, density, and calorific value. For the WCO-based biodiesel, the best blend was WCO B5, with properties closely matching those of petrodiesel. Significantly, the formulations with higher WCO content (e.g., B10 and above) suffered from serious drops (above 8%) in calorific value. In contrast, the RSO diesel blend showed less than 5% drops in calorific value for formulations up to a 20% biodiesel blend (B20). In addition, an indiscernible difference was obtained between the WCO B5, RSO B5, and petrodiesel in terms of engine power, torque, and CO2 emissions, although the RSO B5 did produce less NOx (158 ppm) than both the WCO B5 (390 ppm) and the petrodiesel (220 ppm).

The SRC film containing 1 wt% of TiO2 nanoparticles demonstrated the highest tensile strength. However, with the addition of TiO2 nanoparticles at any concentrations (1, 3, 5, and 7 wt%), the elongation at break of the SRC film decreased in comparison to the SRC film without TiO2 nanoparticles. Moreover, as the concentration of TiO2 nanoparticles increased from 1 to 7 wt%, the moisture content, and water solubility of the SRC films decreased.

This was carried out by treating the dry leaves of Gmelina arborea with methanol and a barium chloride catalyst at 90 °C at varying reaction times in minutes. The products were analyzed using gas chromatography and mass spectrometry (GC-MS). The GC-MS revealed the following results; 162.39, 171.98, 145.69, 92.43, 108.32 and 118.83 mg/g for the reaction times of 10, 20, 30, 40, 50 and 60 minutes, respectively. The maximum yield achieved was 171.98 mg/g at a reaction time of 20 minutes and the minimum yield was 92.43 mg/g at a time of 40 minutes.

The physicochemical properties of the DFSBA-15 were characterized using TEM, BET, and FTIR. The characterization analyses confirmed the formation of fibrous morphology, moderate surface area, and bulk -OH. Several factors, including contact time (min), adsorbent dosage (g/L), pH, and initial concentration (mg/L), were examined for Pb(II) adsorption. The best adsorption performance (89.88%) was attained at 180 min, 1 g/L of adsorbent dosage, pH 5, and 100 mg/L of Pb(II) initial concentration. Pseudo-second-order reaction type and Langmuir isotherm provided good fits to the experimental data, with R2 ≥ 0.9943 and R2 = 0.9982, respectively.
