Introduction The development of alternative and renewable energies is one of the crucial opportunities exhibited by governments to remediate the diminishing resources of the fossil feedstock. Biogases collected from landfill, digester and wastewater plants constitute a large and disposable supply to produce a rich methane stream, though these resources remain mostly unused. The biogas should be...

In this study a composite of activated carbon and carbon nanofiber (AC/CNF) was prepared to improve the performance of activated carbon (AC) for adsorption of volatile organic compounds (VOCs) and its utilization for respirator cartridges. Activated carbon was impregnated with a nickel nitrate catalyst precursor and carbon nanofibers (CNF) were deposited directly on the AC surface using catalyt...

MECHANISM AND KINETICS OF THE REDUCTION OF NITRIC OXIDE BY GRANULAR ACTIVATED CARBON INDUCED BY PdO/Al2O3 IN THE PRESENCE OF O2 by Tian Sang NO x and particulate matter are the main environmental hazards found in Diesel exhaust. In order to explore a novel method to remove NO„ as well as particulate matter, we examined the catalytic reduction of NO x with solid carbonaceous materials as a surro...

The aim of the study is to improve removal of trace organic contaminants dissolved in activated sludge by the process of filtration with membrane bioreactor combined with modified activated carbon, for a maximum removal of organic compounds characterized by low molecular weight. Special treatment was conducted in laboratory on activated carbon. Tow reaction parameters: the pH of aqueous middle ...

the purpose of this study is the utilization of furfural residue for heating energy and activated carbon production. to evaluate the energy production of the residue, bulk density, melting point, and heating value were measured. furthermore, moisture, ash, volatile compounds, fixed carbon, lignin, and elements were determined. ash and volatile content average were measured at 15.4% and 68.9%, r...

the unique properties of air-cooled bainitic steels have been described. a series of mn containing air-cooled bainitic steels invented by authors is presented in this paper: including low carbon granular bainitic steels, low carbon grain-boundary allotriomorphic ferrite/granular bainite duplex steels, medium and medium high carbon bainite/martensite duplex steel, and low carbon carbide free bai...
