The Predictive Content of Energy Futures: An Update on Petroleum, Natural Gas, Heating Oil and Gasoline [PDF]

This paper examines the relationship between spot and futures prices for energy commodities (crude oil, gasoline, heating oil markets and natural gas). In particular, we examine whether futures prices are (1) an unbiased and/or (2) accurate predictor of ...

Liquid–Liquid Equilibrium Data for Refined Olive Pomace Oil + Oleic Acid + Ethanol + Water Systems: Application to Solvent Deacidification

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT This study presents the first experimental liquid–liquid equilibrium (LLE) data for quaternary systems composed of refined olive pomace oil, oleic acid, ethanol, and water at 303.15 K. These data are essential for the design and optimization of solvent‐based deacidification processes, particularly for oils with high free fatty acid (FFA ...

Forecasting the Price of Oil [PDF]

We address some of the key questions that arise in forecasting the price of crude oil. What do applied forecasters need to know about the choice of sample period and about the tradeoffs between alternative oil price series and model specifications?

Comparative Profiles of Lipophilic Nutrients and In Vitro Antioxidant Activity in Commercial Arabica and Robusta Green Coffee Beans

Journal of the American Oil Chemists' Society, EarlyView.
Integrated compositional profiling of ten commercial green coffee lots showed higher mean total phenolic content, DPPH radical‐scavenging activity, β‐carotene, and total phytosterols in Robusta‐labeled lots, whereas Arabica‐labeled lots showed higher mean total tocopherols and total measured fatty acids.

Lubricant Oil Degradation, Condition Monitoring, and Service Life Estimation: A Review

Journal of the American Oil Chemists' Society, EarlyView.
Research framework of the study, integrating lubricant oil degradation, condition monitoring, and service life estimation. ABSTRACT Lubricant oil is often changed on fixed time schedules, even though its real condition depends on load, temperature, and contamination, so good oil is discarded in some cases and degraded oil stays in service in others ...

Crude Oil and Stock Markets: Stability, Instability, and Bubbles [PDF]

We analyze the long-run relationship between the world price of crude oil and international stock markets over 1971:1-2008:3 using a cointegrated vector error correction model with additional regressors. Allowing for endogenously identified breaks in the

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...
