Currently, petroleum hydrocarbons are the most abundantly used chemicals in the world. Manufactured from crude oil, petroleum hydrocarbons are found in gasoline, kerosene, fuel oil, asphalt, and even some chemicals used in home or at work. Almost every person on this planet has once or more used a petroleum product or byproduct. Due to their wide de mand, they are transported all over the world...
Identification of an ignitable liquid in fire debris evidence can be complicated due to evaporation of the liquid, matrix interferences, and thermal degradation of both the liquid and the matrix. In this research, liquids extracted from simulated fire debris were compared to the original liquid using multivariate statistical procedures. Neat and evaporated gasoline and kerosene standards were s...
There is a world-wide demand for clean, reliable and affordable energy. New technologies are needed to produce more oil and natural gas from ‘stranded’ locations. This work is based on gas to liquid (GTL) conversion of natural gas through Fischer-Tropsch (FT) synthesis. Fe & Co based catalysts of varying compositions were prepared in the laboratory and its performance was checked for the FT rea...
Abstract The paper considers the effect of low-amplitude acoustic oscillations on temperature field in flame formed during combustion kerosene gasoline. As a result using IRT-method, sets thermograms process were obtained. For obtained thermograms, distribution high-temperature inhomogeneities plume was analyzed. result, it that causes change height plume, rate. When analyzing spectra changes, ...
Spark ignition (SI) engines fueled with kerosene have broad application prospects in unmanned aviation vehicles. The knock phenomenon of SI is a huge challenge, leading to much lower power output than gasoline engines. In this context, the combustion characteristics blending hydrogen are analyzed numerically regarding working conditions an engine. First, delay time kerosene/hydrogen mixture est...
Liquid fuels(hydrocarbon and peroxide)are flammableand there is a risk of pool fires during their storage and transportation. In order to measure and develop effective methods for protection and considering safety distances, experimental studies and CFD simulations of pool fire of two hydrocarbon fuels (i.e. gasoline and kerosene) and peroxide (TBPB (tert-butyl peroxybenzoate)) were performed. ...
Mercaptans are commonly present in petroleum products. Their foul odor and highly corrosive nature make them the most undesirable sulfur compounds so they should be removed because of environmental issues. Merox process is used for oxidation of mercaptans to disulfide using air in the presence of alkaline solution and Merox catalyst. In this paper, due to lack of information about the kinetic o...
The effect of substrate interferences from high-density polyethylene (HDPE) on the ability to associate an ignitable liquid residue with the corresponding liquid standard, using statistical procedures, is demonstrated. Gasoline, kerosene, and lighter fluid, at three different evaporation levels, were spiked onto HDPE and subsequently burned to generate simulated ignitable liquid residues (ILRs)...
Polycyclic aromatic hydrocarbons (PAHs) are natural, ubiquitous substances in marine environments; they consist of two or more benzene rings fused in various arrangements. A range of biological effects has been demonstrated for these compounds, including acute toxicity, carcinogenicity, mutagenicity, teratogenicity and endocrine disrupting activity (Takeuchi et al., 2009). There are two types o...
A trial to quantify CO2 emission by utilizing our belonging materials has been conducted. For the Polymer electrode membrane Fuel Cell (PEFC) system, the reduction of more than 23% CO2 emission was measured under a practical operation in a family of Okayama prefecture. The statistical data of the CO2 emission obtained from the student’s homes has shown that the highest CO2 emission results from...
