The wonder of an ancient material –Charcoal!
Posted by admin | Under Uncategorized Monday Jul 7, 2008Activated carbons are produced from charcoal involving the burning (Carbonization) of selected raw materials under controlled atmospheric conditions
There are different activated carbons manufactured from various raw materials specially treated to produce a very large surface area ranging from 300 to 2000m2/g this means the internal pore structure which can absorb gases and liquids
Gas masks and water filters are just two of many the uses. Some others include the gold mining industry for extraction food and beverage decolourisation. It is a vital medication as an absorbent of poisons and remedy for stomach problems.
Almost any carbonaceous material; vegetable animal or mineral origin can be converted into activated carbon.
These products have different physical properties and economical characteristics which are selected for particular functions. The starter materials are treated with two basics processes. There are many modifications for the desired product-a high or low density, powdered, granulated and extruded.
The process is initially carbonised to open up the internal pore structure, to increase the pores macro and micro for high absorption the char is subjected to steam or chemical treatment.
It wasn’t until the introduction of gas during the 1st World War that gas masks efficacy was improved.
Did you know that if you are in a survival situation and need to drink polluted water –you can pour water over a crude filter –a cloth containing charcoal –Not the ideal but could save your life – The charcoal itself can also be an efficient fuel for cooking!





























Added. Nice work on this one. Btw, my blog is dofollow, stop by and grab a link. Walter
When these things are remembered no one will marvel at the ease with which Alexander held the Empire of Asia, or at the difficulties which others have had to keep an acquisition, such as Pyrrhus and many more; this is not occasioned by the little or abundance of ability in the conqueror, but by the want of uniformity in the subject state.
Sandra Kellog wrote about it lately but i think what you wrote is much better.
funny, Tony Santos wrote about this topic exactly the other day.
