“…130 There are three phases of the combustion process and there is a CO 2 capture system for every stage of the process. 131 The first phase, known as pre-combustion, involves capturing CO 2 before the combustion process takes place, 132 such as that observed in Integrated Gasification Combined Cycle power plants. The second phase, known as post-combustion, involves separating CO 2 after fossil fuel burning from N 2 and capturing it.…”

The extreme amount of greenhouse gases (GHGs) being released into the atmosphere has proved to be a globally challenging phenomenon that leads to changes in the climate and global warming. The amount of GHGs in the atmosphere has escalated immensely, with a substantial growth of 5.8% in 2010; a similar increase was observed in Pakistan as well. In Pakistan, carbon dioxide (CO2) emissions stand at 54% of total GHG emissions whereas methane, nitrous oxide, carbon monoxide and volatile organic carbon contribute to emissions at 36%, 9%, 0.75% and 0.3%, respectively. One of the key reasons for climatic changes is GHG emission generation from human interventions and activities related to transportation, urban development, industrialization, energy sources, farming and agriculture, waste's improper management, land use and forestry. In 2011, Pakistan's entire GHG emissions were a whopping 347 Mt of CO2‐eq, and by 2050, they are estimated to reach 4621 Mt CO2‐eq. This review evaluates and assesses GHG emissions generating from various sectors in Pakistan, in a socio‐scientific prospect that is caused by human activities and interventions in different economic sectors in Pakistan, endangering the environment across the country. Additionally, the review examines the current level of GHG emissions while accounting for China–Pakistan Economic Corridor–based emissions, abatement strategies including development of a state‐of‐the‐art technique for carbon capture and storage/utilization technologies in Pakistan. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Not only removal of CO 2 from flue gases but also separation of CO 2 from natural gas is crucial because CO 2 decreases the energy density of natural gas and causes corrosion in the transport pipelines . Current CO 2 separation technologies, cryogenic distillation and absorption, are energy‐intensive processes . Alternative separation technologies based on adsorption have been recently developed for efficient capturing of CO 2 from flue gas and upgrading of natural gas .…”

Improving CO₂ Separation Performance of MIL‐53(Al) by Incorporating 1‐n‐Butyl‐3‐Methylimidazolium Methyl Sulfate

et al. 2019

1‐n‐Butyl‐3‐methylimidazolium methyl sulfate is incorporated into MIL‐53(Al). Detailed characterization is done by X‐ray fluorescence, Brunauer–Emmett–Teller surface area, scanning electron microscopy, X‐ray diffraction, Fourier‐transform infrared spectroscopy, and thermogravimetric analysis. Results show that ionic liquid (IL) interacts directly with the framework, significantly modifying the electronic environment of MIL‐53(Al). Based on the volumetric gas adsorption measurements, CO2, CH4, and N2 adsorption capacities decreased from 112.0, 46.4, and 19.6 cc (STP) gMIL‐53(Al) −1 to 42.2, 13.0, and 4.3 cc (STP) gMIL‐53(Al) −1 at 5 bar, respectively, upon IL incorporation. Data show that this postsynthesis modification leads to more than two and threefold increase in the ideal selectivity for CO2 over CH4 and N2 separations, respectively, as compared with pristine MIL‐53(Al). The isosteric heat of adsorption (Qst) values show that IL incorporation increases CO2 affinity and decreases CH4 and N2 affinities. Cycling adsorption–desorption measurements show that the composite could be regenerated with almost no decrease in the CO2 adsorption capacity for six cycles and confirm the lack of any significant IL leaching. The results offer MIL‐53(Al) as an excellent platform for the development of a new class of IL/MOF composites with exceptional performance for CO2 separation.

“…Although biomass gasification has been proven to be one of the most efficient techniques for syngas production, one drawback of this technique is the production of CO 2 in the product stream [13][14][15][16]. As is known, the release of CO 2 is a cause of the greenhouse gas effect; storage or utilization of CO 2 has therefore attracted interest worldwide.…”

Syngas Production from Combined Steam Gasification of Biochar and a Sorption-Enhanced Water–Gas Shift Reaction with the Utilization of CO2

et al. 2019

This research aims at evaluating the performance of a combined system of biochar gasification and a sorption-enhanced water-gas shift reaction (SEWGS) for synthesis gas production. The effects of mangrove-derived biochar gasification temperature, pattern of combined gasification and SEWGS, amount of steam and CO 2 added as gasifying agent, and SEWGS temperature were studied in this work. The performances of the combined process were examined in terms of biochar conversion, gaseous product composition, and CO 2 emission. The results revealed that the hybrid SEWGS using one-body multi-functional material offered a greater amount of H 2 with a similar amount of CO 2 emissions when compared with separated sorbent/catalyst material. The gasification temperature of 900 • C provided the highest biochar conversion of ca. 98.7%. Synthesis gas production was found to depend upon the amount of water and CO 2 added and SEWGS temperature. Higher amounts of H 2 were observed when increasing the amount of water and the temperature of the SEWGS system.
