Cote d'Ivoire is a small mature crude oil producer in West Africa. In 2015, Cote d'Ivoire produced around 27,000 bblsbbl/day (IEA, 2015). Crude oil production started in the early 1980s and peaked in 2006 at 63,000 bblsbbl/day. Today, there are a…
About 85% of petroleum oil need of India is being met through imports. Indian economy is growing steadily resulting in rapid increase of vehicular population and demand for transportation fuels. Indian Government has already mandated blending of…
Volatile organic compounds (VOCs) are abundant in nature and can occur in various forms in a wide variety of sources. Petroleum is one of the major sources of VOCs. Petroleum being the most widely used energy resources of the world, often released to…
One of Sudanese fields has a heavy crude oil which has a high Total Acid Number (TAN) and high viscosity, can cause a lot of problems in production operation, transport, and storage facilities. The effect of ethanol dilution on the rheological…
Carbon neutral solutions are demanded to reduce the greenhouse gas (GHG) emissions from the mobility sector. In Brazil, alongside bioethanol, natural gas and biogas are potential solutions towards a low carbon future. While Brazilian natural gas…
Background Heavy and super-heavy oils are characterized by a high content of resins and asphaltenes, which complicate the transportation and refining of oil and lead to an increase in the cost of refinery products. Currently, of particular interest…
Ethiopia’s transportation sector is currently dominated by internal combustion engine vehicles running using imported petroleum oil. Due to shortages in hard currency, a rising economy and population growth, and rapid industrialization, energy…
The potential for transportation biofuels to displace petroleum fuels is recognized. Biofuels are produced from either cultured or waste biomass. This potential has spurred a tremendous amount of research and development. Yet, past commercialization…
In this paper experimental work was carried out on transportation spark ignition engine using ethanol as a fuel. Ever increasing energy demand and cost of importing crude oil one has to go for alternative transportation fuels. Ethanol is best…
During ethanol fermentation, ethanol accumulates in the medium and becomes a significant stress factor for yeast. Trehalose and glycogen are major carbohydrate storages and presumably protect cells from such stress conditions. In this study, batch…
Hydrilla verticillata contains some active compounds that potential as an antioxidant, antibacterial, anticancer, antimicrobial and antitumor. One of the active compounds in Hydrilla verticillata is steroids. This research aimed to isolate, to…
The aliphatic alcohols (methanol, ethanol, 1- and 2-propanol) were used for the upgrading of petroleum asphaltenes. The process was performed under supercritical (sc) conditions at 350 C. CHNSO analysis and GC methods were used to characterize the…
Bergamot model mixture and crude bergamot essential oil (CBEO) were fractionated in a perforated rotating disc contactor (PRDC) using as solvents ethanol with 30% (Et30) and 40% (Et40) water, in mass. The apparatus performance was evaluated by…
Homogeneous Charge Compression Ignition (HCCI) is a promising advanced combustion concept with high thermal efficiency and low exhaust emissions. This work purposes a computationally-efficient, zero-dimensional (0-D) HCCI combustion model that does…
Rotomolded uncompatibilized composites of LLDPE with softwood and hardwood flour dispersed phases are compared and contrasted with respect to their static (tensile, flexural and impact) and dynamic (creep modelling, storage and loss moduli)…
Homogeneous Charge Compression Ignition (HCCI) is a promising advanced combustion concept with high efficiencies and low emissions. Chemical kinetic mechanisms and ignition delay correlations (IDCs) are often applied to simulate HCCI combustion.…
This paper proposes a novel virtual engine calibration method for alternative fuels using thermodynamic simulation for in-cylinder pressure prediction. Based on known engine data, including the crank angle of the peak cylinder pressure, the…

The limited global crude oil reserve coupled with the environmental worsening caused by the excessive consumption of petroleum-derived fuels, has forced human to look for alternative sources of energy. Ethanol, both renewable and environmentally…
Objective: To find the antitumor compounds from Rabdosia Serra (Maxim) Hara, phytochemical isolation procedures were performed by bioassay-guided fractionation. Methods: The ethanol extract of Rabdosia serra (Maxim) Hara was fractionated by organic…

In this paper, the effect of different types of minerals and alcohols as hydrogen donors on the catalytic aquathermolysis of heavy oil was investigated. The best catalytic effect showed sodium clay. Methanol was demonstrated as the most suitable to…
Reduction in automotive emissions in general, and particulate matter (PM) in particular, may be achieved by substitution of petroleum-based fuel with alternatives. Both partial and complete substitution are feasible. Biodiesel is a class of fluids…
This study assessed the cradle-to-grave life cycle greenhouse gas (GHG) emissions of ethanol production via the fermentation of sugars derived from hot water extraction (HWE) of forest biomass under two processing energy scenarios (biomass, natural…
Tucuma (Astrocaryum vulgare Mart.) is a native South American palm from the Amazon River drainage region. Tucuma fruits contain edible oils presenting high amounts of unsaturated fatty acids in the mesocarp and expressive amounts of saturated fatty…
New technologies to improve the performance and efficiency of internal combustion engines are related to enhance knock resistance in fuels. Aromatics, Paraffins and Lead-based additives in gasoline are used to increase octane rating, but some of…
