Hypercrosslinked polymers (HCPs) are very promising for large-scale applications due to their easy preparation, high thermal stability, and good capability of CO2 capture. Currently, many amine-functionalized porous materials prepared through two steps. In this paper, the HCPs was obtained with a one-step method it showed adsorption up 4.24 mmol/g at 273.15 K. addition, since azo-functionalized...

The combination of growing energy demand and environmental concerns has made the development of CO2 capture and storage technologies a necessity for the near-future energy mix. Post-combustion CO2 capture is one of the most mature technologies for reducing CO2 emissions in power plants. As a next step for the technology development, large-scale demonstration capture plants have to be implemente...

The projections of energy related carbon dioxide (CO2) emissions in the Special Report on Emission Scenarios (SRES) of the Intergovernmental Panel on Climate Change (IPCC) serve as point of departure for an assessment of plausible ranges of CO2 emissions that could be avoided through CO2 capture and storage measures. Scenario and time dependent, sector and fuel specific capture factors are deve...

A mathematical model of a continuous moving-bed temperature-swing adsorption (MBTSA) process for post-combustion CO2 capture in a coal-fired power plant context has been developed. Process simulations have been done using single component isotherms and measured gas diffusion parameters of an activated carbon adsorbent. While a simple process configuration with no gas re-circulation gives quite ...

With the aim to capture and subsequent selective trapping of CO2, a nanocomposite has been developed through selective modification of the outer surface of the halloysite nanotubes (HNTs) with an organosilane to make the nanocomposite a novel solid-phase adsorbent to adsorb CO2 from the atmosphere at standard ambient temperature and pressure. The preferential adsorption of three major abundant ...

A hierarchical computational approach is introduced that combines materials screening with process optimization. This approach leads to novel materials for cost-effective CO2 capture. Zeolites are screened using shape, size, and adsorption selectivities. Next, process optimization is introduced to generate a rank-ordered list based on total cost of capture and compression. We not only select th...

Flue gas from a plant using fossil fuels contains CO2. Thus power/process plants using fossil fuels contribute to climate change if CO2 in flue gas is not captured. The process of CO2 capture from flue gas is called „postcombustion‟ CO2 capture. Existing plants may be retrofitted with this process to minimize CO2 emission. Amine solutions are mostly used for this process to scrub the flue gas. ...

In this work, the CO2 capture capacity of a series of activated carbons derived from recycled polyethylene terephtalate (PET) was tested, facing two problems at the same time: minimising plastic waste and developing an adsorbent for CO2 capture. The PET raw material, obtained from post-consumer soft-drink bottles, was chemically activated with KOH. In addition, a series of nitrogen-enriched act...
