TL;DR: In this article, a green corrosion inhibitor based on rice bran oil was used to prepare green corrosion inhibitors on steel surfaces. And the performance of the synthetized inhibitor was evaluated on a 1018 steel surface by means of different electrochemical techniques such as potentiodynamic polarization, open circuit, linear polarization resistance and electrochemical impedance spectroscopy (EIS).

TL;DR: In this article, an attempt was made wherein ferrofluid is added to rice bran oil methyl ester in the way of analyzing its effects on emission characteristics. And the experimental analysis found a decrease in HC, CO and NOx emissions of 10.8, 9.1% and 8.49% respectively.
Abstract: Increase in NOx emission is one of the important drawbacks for using biodiesel as an alternative for petroleum diesel. Several studies had been carried out to reduce the NOx emissions level in biodiesel. The present work is the result of an attempt wherein ferrofluid is added to rice bran oil methyl ester in the way of analyzing its effects on emission characteristics. Magnetite concentrate is exothermic and is known for its characteristics of releasing copious heat at higher temperatures. Nanofluid using magnetite was synthesized by reacting Iron II (FeCl2) and Iron III (FeCl3) in an aqueous ammonia solution to form Magnetite Fe3O4 (Ferro fluid). Release of heat by magnetite during the combustion process would counterbalance the conventional limitations related with biodiesel such as increased delay period, inferior combustion rate and higher NOx emissions etc. Experiments were conducted with Rice Bran Oil Methyl Ester (RBOME) and Rice Bran Oil Methyl Ester with addition of ferrofluid (RBOMEF) and are compared with petroleum diesel. RBOMEF was prepared comprising 97.7% biodiesel, 2% magnetite based ferrofluid and 0.3 % surfactant by volume was used in a Compression Ignition engine. The experimental analysis found a decrease in HC, CO and NOx emissions of 10.8%, 9.1% and 8.49% respectively.

TL;DR: In this article, aqueous enzymatic extraction was investigated for recovery of oil from mustard seed and rice bran, and the extraction process was reproducible based on statistical analysis of extraction data under different extraction conditions.
Abstract: Aqueous enzymatic extraction was investigated for recovery of oil from mustard seed and rice bran. The extraction process was reproducible based on statistical analysis of extraction data under different extraction conditions. The most significant factors for extraction were the time of digestion with enzymes, seed or bran concentration in water, volume of hexane added before recovery, and amount of enzyme(s) used. The pretreatment steps of each material before enzyme digestion influenced oil yield.

TL;DR: In this paper, the magnetic nano particles (magnetite) can be collected from exhaust using magnetic billets in the tail pipe to reduce viscosity and other related problems associated with biodiesel by adding non polluting additives.
Abstract: The objective of this work is to reduce viscosity and other related problems associated with biodiesel by adding non polluting additives. Magnetite is chosen as an additive in this work. Significant reason for using magnetite as an additive is that the magnetic nano particles (magnetite) can be collected from exhaust using magnetic billets in the tail pipe. Performance and emission test is carried out in single cylinder compression ignition engine using base and modified fuel and is compared to diesel. Modified fuel consists of 98.5% base fuel (Rice bran oil methyl ester), 1.3% additives (magnetite) and 0.2% surfactant (tri methyl ammonium hydroxide) by volume. The experimental work confirmed that by adding magnetite to methyl esters of rice bran oil enhances the brake thermal efficiency by 4.27% with 5.17% reduction in SFC. In addition, 10.8%, 9.1% and 8.49% reduction in HC, CO and NOx emissions is observed respectively.

TL;DR: In this article, the presence of light and heavy polycyclic aromatic hydrocarbon (PAH) residues using liquid-liquid extraction, cleanup on a silica gel column, and resolution and determination by HPLC using a fluorescence detector was analyzed.
Abstract: Edible oils such as coconut, groundnut, hydrogenated vegetable, linseed, mustard, olive, palm, refined vegetable, rice bran, safflower, sesame, soybean, and sunflower were analyzed for the presence of light and heavy polycyclic aromatic hydrocarbon (PAH) residues using liquid-liquid extraction, cleanup on a silica gel column, and resolution and determination by HPLC using a fluorescence detector. Ten PAH viz. acenaphthene, anthracene, benzo(a)pyrene, benzo(e)pyrene, benz(ghi)perylene, chrysene, coronene, cyclopenta(def)phenanthrene, phenanthrene, and pyrene were monitored. Analysis of 296 oil samples showed that 88.5% (262) samples were contaminated with different PAH. Of 262 contaminated edible oil samples, 66.4% of the samples showed PAH content of more than the 25 μg/kg recommended by the German Society for Fat Science. The total PAH content was highest in virgin olive oil (624 μg/kg) and lowest in refined vegetable oils (40.2 μg/kg). The maximum content (265 μg/kg) of heavy PAH was found in olive oil and the minimum (4.6 μg/kg) in rice bran oil. Phenanthrene was present in 58.3% of the oil samples analyzed, followed by anthracene (53%). Among the heavy PAH, benzo(e)pyrene was observed in 31.2% of the samples followed by benzo(a)pyrene (25.5%). The intake of PAH was highest through olive oil (20.8 μg/day) followed by soybean oil (5.0 μg/day) and lowest through refined vegetable oil (1.3 μg/day). Based on these monitoring studies, international and national guidelines for permissible levels of PAH can be prepared so as to restrict the intake of these toxic contaminants.
