Animal manure continues to represent a significantly large and problematic portion of the US agricultural waste generated yearly. Granular activated carbons made from pelletized poultry litter have been shown to adsorb various positively charged metal ions from laboratory-prepared solutions. The objective of this study was to develop a conceptual capital and operating cost estimate using the Su...

Activated carbon is one of the mainstay technologies for the decolorization of raw sugar to produce refined sugar products. This paper discusses issues relevant to the application of granular activated carbon in the sugar refining industries. The topics covered include evaluating the performance of recycled adsorbents, the evolution of activated carbon properties during initial activation and r...

ZnO/activated carbon nanocomposites (ZnO/ACns) were synthesized by applying two different solid-state and precipitation methods. Precipitation method was initiated with zinc chloride and sodium hydroxide as starting materials in the presence of activated carbon. The synthesized sample was calcined at 250 °C for 1 h. The preparation of nanocomposite by solid-state method was accomplished by heat...

Conventional drinking water treatment is inefficient in removing a large fraction of known organic micropollutants (OMPs). Ozonation combination with granular activated carbon promising approach for addressing this issue.

Adsorbed natural gas (ANG) by Granular Activated Carbon (GAC) has been widely investigated as an alternative to CNG and LNG technologies for storage and transportation of natural gas. In the present work, a theoretical and experimental study was conducted to accurately determine the amount of adsorption of CH4 by GAC. To carry out the experiments, the volumetric method was used up to 4 MPa at c...

The use of powdered activated carbon for fouling control in the membrane processes is limited by some secondary problems associated with its use, like cake formation, long backwash times and blackening of pipes. Granular activated carbon (GAC) was used as an alternative of powdered activated carbon due to its large particle size which was kept from being entering into the membrane system. The s...

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...

The objective of this investigation was to evaluate pecan and almond shell-based granular activated carbon’s viability to effectively remove organic and inorganic pollutants in municipal wastewater compared to commercial carbons, Filtrasorb 200 (bituminous coal-based), and GRC-20, 206C AW (coconut shell-based). The solution to the objective was approached under three distinct phases, namely (I)...
