Beneficiation Of Pyrolitic Carbon Black [PDF]

open access: yesWorld Academy of Science, Engineering and Technology, International Journal of Chemical, Molecular, Nuclear, Materials and Metallurgical Engineering, 2013
This research investigated treatment of crude carbon black produced from pyrolysis of waste tyres in order to evaluate its quality and possible industrial applications. A representative sample of crude carbon black was dry screened to determine the initial particle size distribution.

Microporosity in carbon blacks [PDF]

open access: yesCarbon, 2002
Microporous carbon blacks can be characterized by the same techniques as activated carbons, using the classical DR equation and comparison plots based on non-porous materials. The CO2 adsorption isotherm at 273 K, combined with computer modelling, also leads to an assessment of microporosity.

Are there "black holes" in carbonate deposystems?

open access: yesGeologica Acta, 2004
The likelihood that extensive dissolution of aragonite (and high magnesian calcite) takes place during very early burial, even in relatively shallow tropical settings, has wide implications for interpreting and modelling ancient limestones. Some low energy environments may constitute net sinks ("black holes") for carbonates.

Recommendations for reporting "black carbon" measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Abstract. Although black carbon (BC) is one of the key atmospheric particulate components driving climate change and air quality, there is no agreement on the terminology that considers all aspects of specific properties, definitions, measurement methods, and related uncertainties.

Cycling of black carbon in the ocean [PDF]

open access: yesGeophysical Research Letters, 2016
AbstractBlack carbon (BC) is a by‐product of combustion from wildfires and fossil fuels and is a slow‐cycling component of the carbon cycle. Whether BC accumulates and ages on millennial time scales in the world oceans has remained unknown. Here we quantified dissolved BC (DBC) in marine dissolved organic carbon isolated by solid phase extraction at ...

Black carbon affects the cycling of non-black carbon in soil

open access: yesOrganic Geochemistry, 2010
Abstract Black carbon (BC) is an important fraction of many soils worldwide and plays an important role in global C biogeochemistry. However, few studies have examined how it influences the mineralization of added organic matter (AOM) and its incorporation into soil physical fractions and whether BC decomposition is increased by AOM.

Dispersion of carbon black

open access: yesPolymer Testing, 1984
Abstract Satisfactory dispersion of the carbon black is essential to the production of rubber compounds possessing the maximum possible resistance to wear, tensile strength and abrasion resistance. The methods used to measure/estimate the degree of dispersion are reviewed in this paper.
