reduction of methoxyketon 1 by nabh4 gives methoxyketol 2. allthough acetate and tosylate of this alchohol were not seprated, benzoate ester was isolated. reduction of ketol 2 by lialh4 gives alchohol 4. ketol 9 does not react with methyl magnesium iodide, but methoxyketon 1 react with both methyl magnesium iodide and phenyl magnesium iodide gives corresponding hydrocarbons. keton 13 with pheny...

Petrophysical evaluation of petroleum reservoirs is one of the most challenging tasks for hydrocarbon reserve determination. One critical petrophysical parameter is the water saturation which is normally calculated from Archie’s equation. Carbonate reservoirs, however, due to their complex mineralogy are not good candidates for Archie’s equation because Archie’s parameters are strongly dependen...

Optimization of the light conditions for biofuel production by the microalga Botryococcus braunii BOT-22 (race B) was performed using monochromatic red light. The lipid and sugar contents were approximately 40% and 20-30% of the cell dry weight, respectively, and about half of the lipids were liquid hydrocarbons. The half-saturation intensities for the production rate of lipids, hydrocarbons, a...

The entrapment of residual hydrocarbon globules by water table fluctuations can produce a long-term contamination threat to groundwater supplies that is difficult to remove. The mobilization of entrapped hydrocarbon globules depends on the balance between capillary and gravitational forces represented by the Bond number. It is important to estimate the potential for hydrocarbon entrapment at a ...

catalysts with the formula of laco(1+x)o(3+δ), where 0 ≤ x ≤ 1, were studied for oxidation of co and c2h6 in a synthetic exhaust gas, comprising 6.0 % co and 0.2 % c2h6 in ar. ethane was selected as a model for hydrocarbons in the exhaust gas. the performance of catalysts is correlated to their properties, particularly their redox in oxidizing and reducing atmospheres. xrd patterns show perovsk...

One hundred and thirty-five soil samples were collected from a depth of 2–2.5 m near oil and gas fields of Tatipaka, Pasarlapudi, Ponnamanda, Kaza and Palakollu areas of Krishna–Godavari Basin, Andhra Pradesh, India and were analysed for light hydrocarbon gases. The adsorbed soil gas analysis showed the presence of moderate to low concentrations of methane (CH4; 2–83 ppb), ethane (C2H6; 1–92 pp...

Light hydrocarbons accumulated in subsurface soil by long-term microseepage could favor the anomalous growth of indigenous hydrocarbon-oxidizing microorganisms, which could be crucial indicators of underlying petroleum reservoirs. Here, Illumina MiSeq sequencing of the 16S rRNA gene was conducted to determine the bacterial community structures in soil samples collected from three typical oil an...
