A potential degrader of paraffinic and aromatic hydrocarbons was isolated from oil-contaminated soil from steel plant effluent area in Burnpur, India. The strain was investigated for degradation of waste lubricants (waste engine oil and waste transformer oil) that often contain EPA (Environmental Protection Agency, USA) classified priority pollutants and was identified as Ochrobactrum sp. C1 by...

Two bacterial strains phylogenetically identified as Pseudomonas aeruginosa strains RM1 and SK1 displayed extensive degradation ability on waste engine oil (SAE 40W) in batch cultures. Spectrophotometric analysis revealed the presence of various heavy metals such as lead, chromium and nickel in the waste engine oil. The rate of degradation of waste engine oil by the isolates, for the first 12 d...

investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (lhr) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].the engine had different operating conditions...

The increasing vehicular population causing consumption of petroleum fuels at a faster rate and causes increase in the danger of petroleum fuels depletion and the remarkable increase in high crude oil prices. The increasing consumption of petroleum products has been a matter of great concern for the country for the financial growth as well as environmental pollution abatement. The situation off...

it is known that native oil-degrading microorganisms are ubiquitous. they can be isolated from contaminated soils. in this study, biodegradation experiments were carried out to evaluate the efficiency of pollutant removal by adding the selected microorganisms. five mixed cultures and 3 single bacteria strains, pseudomonas sp., arthrobacter sp. and mycobacterium sp. were isolated from hydrocarbo...

This study deals with artificial neural network (ANN) modeling a diesel engine using waste cooking biodiesel fuel to predict the brake power, torque, specific fuel consumption and exhaust emissions of engine. To acquire data for training and testing the proposed ANN, two cylinders, four-stroke diesel engine was fuelled with waste vegetable cooking biodiesel and diesel fuel blends and operated a...

Increase in energy demand, stringent emission norms and depletion of oil resources have led the researchers to find alternative fuels for internal combustion engines. On the other hand, waste oils pose a very serious environment challenge because of their disposal problems all over the world. In this context, waste oils are currently receiving renewed interest. The properties of the oil derived...

Waste sardine oil, a byproduct of fish industry, was employed as a low cost feedstock for biodiesel production. It has relatively high free fatty acid (FFA) content (32 mg KOH/g of oil). Lipase enzyme immobilized on activated carbon was used as the catalyst for the transesterification reaction. Process variables viz. reaction temperature, water content and oil to methanol molar ratio were optim...

in accordance with waste strategy for turkey, the study was carried out to analyses waste engine crankcase oils and waste gearbox oils generated from vehicle maintenance services in order to determine their suitability for recycling, recovery or final disposal based on regulation published by turkish ministry of environment and forestry on 21 january 2004. the regulation requires all waste oil ...
