COAL-BASED ACTIVATED CARBON FOR PRESSURE-SWING ADSORPTION
PK-1560 is a kind of coal-based extruded activated
carbon developed by SHANXI for pressure-swing
adsorption. Physical activation: The precursor is developed
into activated carbons using gases. This is generally done
by using one combination of the following processes:
1.)Carbonization: Material with carbon content is
pyrolyzed at temperatures in the range of 300–700℃, in
absence of oxygen (usually in inert atmosphere with gases
like argon or nitrogen) .
2.)Activation/ Oxidation: Raw material or carbonised
material is exposed to oxidizing atmospheres (carbon
monoxide, oxygen, or steam) at temperatures above
700℃ , usually in the temperature range of 700–900℃ .
The product is also designed to comply with all the
applicable provision of AWWA standard for extruded
PK-1560 is used primarily to separate hydrogen from
blast furnace gas or from the methyl alcohol gas. This
carbon is a coarser mesh media and is generally used in
deep bed filters where pressure drop may be concerned.
PK-1560 functions as a dual purpose media provide both
filtration and adsorption.
Iodine Number 1010 mg/g (min)

Having high hardness, the product can reduce
the generation of fines and product losses during
Complicated pores structure provides an equal
blend of low and high energy, also for effective
removal of abroad range of high and low molecular
weight organic compounds.
Separating nitrogen and carbon dioxide from the air.
Separating methane from ferment gas.
