Precursor suitability and pilot scale production of super
activated carbon for greenhouse gas adsorption and fuel

Raw and calcined petroleum cokes of Indian origin were
characterized and screened as a carbon precursor for the
preparation of activated carbon on medium and pilot scale
by chemical activation method. Raw petroleum coke (RPC)
was found more suitable precursor for preparation of
activated carbon, whereas the enhanced graphitic
arrangement limits the applicability of calcined
petroleum coke. The suitability of petroleum coke as
activated carbon precursor was correlated with its
physical properties. Super activated carbon (SAC)
obtained from RPC exhibited very high specific surface
area (3578 m2 g−1) with ultra-microporosity ranges from
0.4 to 0.7 nm. The equilibrium adsorption of CO2, CH4,
CO, and N2 measured on powder SAC at different
temperatures evidenced its applicability for gas
separation through high adsorption capacity and
selectivity. SAC also showed the high fuel gas storage
capacity, H2 (26.67 mmol g−1 at 77 K and 3000 kPa) and
CH4 (10.87 mmol g−1 at 303 K and 3700 kPa) due to its
high specific surface area and microporous textural
property. The production of SAC was also demonstrated for
pilot scale and examined for CH4 storage.

The transformation of powder SAC into pellets using
bentonite clay as a binder to provide better mechanical
strength with enhanced CH4 adsorption (on a volume basis)
made it viable for practical application.
