In the last decade, deep eutectic solvents (DESs) are receiving more importance primarily
because of their easy synthesis and unique properties. Furthermore, the large number of …

Management and disposing of used lubricating oil (ULO) poses deleterious effects to air,
land and water pollution. These contaminants not only causes environmental problems, they …

Engine oils are contaminated with hazardous species resulted from the oxidative
degradation, which cause serious environmental issues. In this study, the extraction of useful …

Amidst the global effort in energy transition from fossil fuel remains a challenge for the
heavily dependent oil and gas (O&G) industry. Thus, the circular economy (CE) concept …

Conventional recycling processes cannot recycle the residual lubricating base oil contained
in waste lubricating oil. Thus, an all-component recycling process was proposed to recover …

The oil and gas (O&G) industry has recently faced market headwinds due to high
environmental impacts generated. Therefore, this study proposes to develop a circular …

Lubricant oil is commonly used to reduce friction and prevent corrosion. It also protects the
metallic components of the machine from wear and tear due to continuous operation …

Recycled engine oil was produced from used engine oil (15W-40) using a combination of
MEK and 1-butanol solvents with an activated carbon adsorbent through the adsorption …

Purpose As lubricating oils are used, their performance deteriorates and they become
contaminated. The purpose of this paper is to investigate the lubrication performance of …

Refining of waste mineral oils is usually done by distillation or acid/clay methods, or a
combination of both. In this study, waste oil refining was carried out in order to obtain higher …
