G

raphene based adsorbent has been introduced as the next

generation CO

2

adsorbent by the scholars since 2012. CO

2

adsorption capacity on these adsorbents as an indicator has

been reported to evaluate their performance in comparison

with other adsorbents in the literatures. This parameter is

easily estimated by CO

2

adsorption isotherm data. On the

other hand, these indicator doses not present the performance

of the adsorbents in their end utilization. Recently, some

scholars develop an indicator called the efficiency indicator to

evaluate the performance of the adsorbents in the idealized

pressure swing adsorption (PSA) process. This new indicator

is defined as the amount of captured CO

2

to energy needed

for compressing the gaseous mixture in the PSA process.

In this study, for the first time, the recent indicator was used

to evaluate the performance of CO

2

capture on mesoporous

graphene oxide - TiO

2

nanocomposite. This adsorbent was

synthesized and characterized by N

2

adsorption-desorption

measurements, X-ray diffraction, field emission scanning

electron microscopy and FT-IR spectroscopy. Subsequently,

the pure single-component adsorption isotherms, including

CO

2

and N

2

were measured at 298 K to assess the efficiency

indicator of CO

2

capture on mesoporous graphene oxide - TiO

2

nanocomposite for different type of thermal power plant. The

CO

2

:N

2

binary gas mixtures, including the molar ratio of 5:95,

8:92, 10:90and15:85wereconsidered tocalculate this indicator

for combined cycle power plant, natural gas-fired steam power

plant, heavy oil-fired steam power plant and coal-fired steam

power plant respectively. The efficiency indicator of CO

2

capture on mesoporous graphene oxide-TiO

2

nanocomposite

was calculated to be 2.136, 1.170, 0.875 and 0.432 tonne/

GJ for above mentioned power plants. Besides, the results

indicated that CO

2

capture on this adsorbent had the higher

efficiency in comparison with other adsorbents, including

three-dimensional graphene based porous adsorbent, holey

graphene frameworks, thermally treated graphene nanosheets

and activated carbon.
