Research ArticleOpen accessEvery word in the titleMethanol-Based Transesterification Optimization of Waste Used Cooking Oil over Potassium Hydroxide CatalystCholada Komintarachat, Sathaporn ChuepengProblem statement: Waste used Cooking Oil (WCO) harmfully affected to environment and human’s health can be a feedstock for producing biodiesel. Approach: The conversion of Fatty Acid and Free Fatty Acid (FFA) of WCO with 15.0% w/w FFA content to biodiesel was studied through transesterification reactions. This work investigated the effects of alcohol and catalyst quantity, reaction time and temperature … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 9,739 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleThe Recovery of Used Palm Cooking Oil Using Bagasse as AdsorbentRizki Wannahari, Mariam Firdhaus Mad NordinProblem statement: The use and reduce cooking oil is a common phenomena in our society. While some of this cooking oil is further refine most of it however and not subject to any filtration in the refining process medium such as carbon active, silica are commonly use. Approach: The used of bagasse as adsorbent is not common. This is odd … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 2 Mar 2012 · 10,315 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleStudy of Properties of a Dispersant Used for Extracting Oil with High Gas-Oil RatioVladimir Verbitsky, Aleksey Dengaev, Oleg Zubkov, Dmitry KoshkinThe article presents the bench test results for a dispersant manufactured by Izhnefteplast Company, which specializes in batch production of unique submersible pumping equipment for oil extraction. The submersible equipment is unique in that the working elements of the pumping equipment are made of polymeric materials unlike the conventional concept of pumping machinery for oil production. The relevance of the … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 24 Feb 2016 · 7,293 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsOptimization of Biodiesel Production from Spent Palm Cooking Oil Using Fractional Factorial Design Combined with the Response Surface MethodologyS.M. Zakir Hossain, Nahid Sultana, Muhammad Faisal Irfan et al.Fractional Factorial Design (FFD) of the experiments combined with the response surface methodology was used to determine the optimum conditions for the production of biodiesel from Used Cooking Oil (UCO) in a batch reactor. Spent palm olein cooking oil was used as a raw material for biodiesel production as it is commonly used in most of the restaurants in Bahrain. … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 22 Nov 2016 · 8,443 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,101 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsRemoval of Dye from Textile Wastewater Using Plant Oils Under Different pH and Temperature ConditionsA.S. Mahmoud, Abdel E. Ghaly, M.S. BrooksThe effectiveness of five plant oils (cottonseed, olive, canola sunflower and used cooking oil) for the removal of dye from textile wastewater was evaluated. The study revealed that the dye removal efficiency increased as the temperature was increased. Under low pH, both the oil and dye split into two components each. Neither one of the oil components joined with either … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 8,351 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Antioxidant Effects of Essential Oil Blends and Individual Oils Using the DPPH Radical-Scavenging AssaySunghun Jang, Jae Kyung KimOxidative stress is recognized as a major contributor to conditions such as cancer, aging, and inflammation. Consequently, there is a growing interest in the use of natural antioxidants, particularly essential oils, owing to their safety benefits and potent antioxidant properties. The aim of this study was to evaluate the antioxidant effects of four essential oil blends (Refresh, Zest, Revitalizing, and … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 5 Jan 2026 · 2,648 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Analysis of Laboratory Measured and PVTP Software DataOluwasanmi Samuel Teniola, Mercy Isaiah OkegbemiCubic Equations of State (EOS), including the Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) models, are foundational in petroleum engineering for modeling the thermodynamic behavior of hydrocarbon systems. These EOS are widely used to predict phase behavior and Pressure-Volume-Temperature (PVT) properties, which are crucial for reservoir simulation, production forecasting, and enhanced oil recovery. However, their predictive accuracy diminishes when applied to complex … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 20 Dec 2025 · 2,761 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIsolation and Identification of Bacteria Leading to Microbial Spoilage of Sweet Potato and Screening for Antistaling Agents Running HeadDaoqi Liu, Huili Liu, Yuanyuan Dang et al.To develop natural preservatives tailored for sweet potatoes, the control effect of essential oils on the spoilage microorganisms of sweet potatoes is uncertain. Therefore, we first isolated and identified the dominant spoilage bacteria from spoiled sweet potatoes. Micrococcus aloeverae, Priestia aryabhattai, and Glutamicibacter arilaitensis were identified through screening, morphological observation, gram staining, and 16S rDNA assays. Subsequently, five plant essential … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 26 Apr 2024 · 5,221 accessesView PDF Cite
