The massive consumption of fossil fuels and associated environmental issues are leading to an increased interest in alternative resources such as biofuels. The renewable biofuels can be upgraded from bio-oils that are derived from biomass pyrolysis. Catalytic cracking and hydrodeoxygenation (HDO) are two of the most promising bio-oil upgrading processes for biofuel production. Heterogeneous cat...

The Deepwater Horizon oil spill in 2010 overlapped with the spawning of many pelagic fish species in the Gulf of Mexico, including mahi-mahi (Coryphaena hippurus). Polycyclic aromatic hydrocarbons (PAHs) released during the spill have been shown to cause photo-induced toxicity under ultraviolet (UV) radiation. In the present study, mahi-mahi embryos were exposed to high-energy water accommodate...

Syntrophic acetate oxidation coupled to hydrogenotrophic methanogenesis has been identified as a significant anaerobic pathway in high-temperature (55°C) oil fields (1, 2). In a paper on acetate production from oil under sulfate-reducing conditions, Callbeck et al. (3) took note of that observation, only to emphatically state that “syntrophic acetate oxidation coupled to hydrogenotrophic methan...

Thermal cracking of heavy oil residues has gained the attention refineries due to increasing need for light fractions, as well its lower value compared fractions. In this paper, thermal process residual crude that product from atmospheric distillation towers in Samawah Refinery was studied order convert into a lighter oil. API gravity and conversion ratio result been adopted indicators accuracy...
