Thermal cracking of complex organic matter can occur under many geological settings. However, the role thermal vs. other chemistries (e.g., metallic catalysis or Fischer-Tropsch-type reactions) in petroleum formation remains controversial. Realistic modeling isotope effects chemical reaction networks involving might shed light on this problem, especially given recent progress measurements intra...

Alkanes are the major components of crude oil and the most abundant and available carbon and energy sources in reservoirs. Microorganisms are common inhabitants of these environments and may have effective biodegrading strategies, based on specialized enzyme systems and metabolic pathways, as a form to access hydrocarbons as carbon and energy sources. However, the current knowledge of the micro...

introduction persian gulf is one of the most important water pathways in the world that has been heavily developed for crude oil production, transportation and exportation. it is well established that such activities result in contamination of the marine environment by petroleum and petroleum productions. the persian gulf represents a highly stressful environment due to prevailing natural condi...

Petroleum products play a major role in fueling the economy of the world but the pollution they create has become a critical issue. Understanding the diversity present in pipeline muck will help with the exploration of new microbial strains with better hydrocarbon degrading capacities for bioremediation of polluted sites. This study provides an analysis of petroleum muck using next generation s...

The world energy paradigm is changing from one based on petroleum to one based on a mixture of energy platforms. This change is precipitated by a finite petroleum supply, an expanding global demand, and political instability in areas with major petroleum reserves. The mixed energy platform will include an array of renewable energy sources. The agricultural and forestry sectors have the potentia...

Although polycyclic aromatic hydrocarbons (PAHs) have usually been found to persist under strict anaerobic conditions, in a previous study an unusual site was found in San Diego Bay in which two PAHs, naphthalene and phenanthrene, were oxidized to carbon dioxide under sulfate-reducing conditions. Further investigations with these sediments revealed that methylnaphthalene, fluorene, and fluorant...

The purpose of the present work is to show that light straight-run gasoline fraction can be used as feedstock for hydro-catalytic isomerization process, and isomerized product serve a component obtaining pure ecological commercial brand Euro-4 Euro-5. Transformation n-alkanes Zhanazhol oil’s with boiling temperature 180°C was studied. Isomerization carried out in flow unit stationary layer modi...

Forecasting of oil prices has always been a matter of great importance due to its influence in driving a country’s economy. As a matter of fact, the petroleum industry is considered to be the biggest contributor in the industrial sector in terms of providing raw materials to the other industries and generating revenues. Due to the non-linear and unpredictable nature of the oil prices, a lot of ...

The fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. Biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. Therefore, the production of petroleum-like fractions from nonedible oil e...
