Powder and lumps of the Argonne Premium Upper Freeport coal were compared in a 9monthlong CO2 sorption−desorption study. On the basis of the slope analysis, CO2 induced the lumps swelling by 7%. The powder swelled by 8% and then rapidly shrank by 3% on desorption. This was verified by a "single point" injection of helium and the pressureanddensity technique, which was sufficiently ...

Activated charcoal is a fine, odorless, black powder. It is produced by heating charcoal to an extremely high temperature in an environment without oxygen, such as a tank. Once activated, the powder's pores trap chemicals, making it effective at treating overdoses and chemical poisonings by preventing the body from absorbing the toxic substances.
