Carbon manufacture

Adsorption. Adsorption involves the transfer of a component onto a solid surface. An example is the adsorption of organic vapors by activated carbon. Activated carbon is a highly porous form of carbon manufactured from a variety of carbonaceous raw materials such as coal or wood. The adsorbent may need to be... 

Uses. Hiere are several different grades of barium carbonate manufactured to fit the specific needs of a wide variety of applications very fine, highly reactive grades are made for the chemical industry coarser and more readily haridleable grades are mainly supplied to the glass industry ...

Critoph and Turner [15] carried out similar direct measurements for ammonia and 208C (coconut shell based) carbon manufactured by Sutcliffe Speakman Carbons. The bed conductivity was found to be around 0.165 W/mK at concentrations less than 20% and to rise to 0.19 W/mK at 25% concentration. The corresponding grain conductivities rose from 0.85 to 1.25 W/mK respectively. The higher grain conductivity than that found by Gurgel and Grenier may reflect the different structures present within the extmded and nut shell carbons.

Innovatory boronated carbons (manufactured in the Institute of Chemistry and Technology of Petroleum and Coal, Wroclaw University of Technology, Poland) were obtained by co-pyrolysis of coal-tar pitch with a pyridine-borane complex. In the first stage of pyrolysis (520°C) the so-called semi-coke is obtained. Further carbonization at 2500°C leads to obtaining boron-doped carbonaceous material (sample labeled 25B2).

Carbon Manufacture. The history of Chinese ink indicates that the carbon was made in at least two ways—viz., by burning wood, usually pine, or by burning oil. However, other fuels may also have been used. 

How far particle size analysis will lead is uncertain. At an elementary level, the ability to confirm or deny the identity of ink in two areas of the same painting would itself be useful (—e.g., in assessing the authenticity of a signature). This author s opinion is that the differentiation of lampblack inks is likely to be difficult or impossible because of the reproducible conditions of carbon manufacture. With pine soot inks (and perhaps others, if they exist) the position is more hopeful since fortuitous circumstances may show that ink made in one place differs from that made in another. With regard to the history of ink, this approach could be applied more often to earlier paintings, and its potential value is obvious.

Activated carbon is a finely divided form of amorphous carbon manufactured from the carbonization of an organic precursor, which possesses a microporous structure with a large internal surface area. The ability of the hydrophobic surface to adsorb small molecules accounts for the widespread applications of activated carbon as gas filters, decoloring agents in the sugar industry, water purification agents, and heterogeneous catalysts.
