Since its beginnings in the mid-nineteenth century, oil refining technology has evolved a continuous process of adaptation to demands society, matters as vital supply energy, lighting, transportation or new materials improve quality life. In that time, this been one greatest examples how technological innovation an industry contributes welfare and development society. The objective manuscript i...

Soil contamination by used lubricating oil from automobiles is a growing concern in many countries, especially in Asian and African continents. Phytoremediation of this polluted soil with non-edible plant like Jatropha curcas offers an environmental friendly and cost-effective method for remediating the polluted soil. In this study, phytoremediation of soil contaminated with 2.5 and 1% (w/w) wa...

Solid coconut waste was produced after coconut milk extraction process and may still contain up to 24 wt.% oil content. In this work, extraction of oil from coconut waste using batch and soxhlet extractor was studied. Effect of particle size diameter, type of solvent and solvent to solid ratio on the kinetic and thermodynamic parameters; entropy, enthalpy and free energy of extraction were inve...

Virgin olive oil (VOO) is obtained exclusively by mechanical extraction from the olive fruit and can be consumed crude without any further physical-chemical treatments of refining. Its sensory and health properties are intimately linked to its chemical characteristics, in particular to several minor components, which are strongly affected by the operative conditions of oil processing and can th...

Phospholipase C catalyzes the hydrolysis of the sn-3 phosphate head group in phospholipids including phosphatidylcholine, phosphatidyletanolamine, and phosphatidylserine with the formation of 1,2-diacylglycerol and water soluble phosphate esters phosphorylcholine, phosphorylethanolamine, and phosphorylserine. Phospholipase C from P. pastoris is intended for use in the refining of soybean oil an...

This study explores the impact of oil depletion on the energetic efficiency of oil extraction and refining in California. These changes are measured using energy return ratios (such as the energy return on investment, or EROI). I construct a time-varying first-order process model of energy inputs and outputs of oil extraction. The model includes factors such as oil quality, reservoir depth, enh...

Two antioxidative compounds were isolated from the oil of sesame seeds roasted at 230°C for 15 min and identified as sesaminols (isomers) by MS and NMR analysis. Although sesaminols are present in refined unroasted sesame seed oil, we have demonstrated their presence also in the oil from the roasted sesame seed without refining for the first time. Furthermore, the amounts of sesaminols in sesam...

The protection of the environment and pollution control are issues paramount importance. Researchers today engrossed in mitigating harmful impacts petroleum waste on environment. Lubricating oils, which essential for smooth operation engines, often disposed improperly after completing their life. In experimental work presented this paper, deteriorated engine oil was regenerated using acid treat...
