Carbon management and sequestration offers an opportunity for reducing greenhouse gas emissions that can complement the current strategies of improving energy efficiency and increasing the use of non-fossil energy resources. When most people think of sequestering carbon, they think of planting trees. However, the focus of this paper is the capture of CO 2 from large stationary sources, primaril...

Composites incorporating two-dimensional nanostructures within polymeric matrices have potential as functional components for several technologies, including gas separation. Prospectively, employing metal-organic frameworks (MOFs) as versatile nanofillers would notably broaden the scope of functionalities. However, synthesizing MOFs in the form of freestanding nanosheets has proved challenging....

Introduction World economy at present relies on burning fossil fuels to produce affordable energy. A consequence of the use of these fuels is the emission of large amounts of carbon dioxide (CO2) to the atmosphere creating environmental problems such as global climate warming. In the near future, if CO2 emission regulations are enforced, industry will require improved technologies for the effic...

Carbon dioxide gas separation is important for many environmental and energy applications. Molecular dynamics simulations are used to characterize a two-dimensional hydrocarbon polymer, PG-ES1, that uses a combination of surface adsorption and narrow pores to separate carbon dioxide from nitrogen, oxygen, and methane gases. The CO2 permeance is 3 × 10(5) gas permeation units (GPU). The CO2/N2 s...

Ionic liquids (ILs) are proposed as potential “green” solvents with remarkable properties. Deep eutectic (DESs) a new type of ILs additional properties, such higher biodegradability and lower price. DESs absorbents for various gas separations, CO2/N2, CO2/H2/CO, H2S/CH4, N2O/N2. Due to their large number, the screening is crucial. Although high absorption capacities were screened using solubili...

Because of the high separation performance and easy preparation, mixed-matrix membranes (MMMs) consisting of metal-organic frameworks have received much attention. In this article, we report a novel ZIF-300/PEBA MMM consisting of zeolite imidazolate framework (ZIF-300) crystals and polyether block amide (PEBA) matrix. The ZIF-300 crystal size was effectively reduced by optimizing the hydrotherm...

A new CO2/CH4 gas separation process is presented in this paper. Capture of CO2 from natural gas is carried out using an n-alkane solvent in a conventional physical absorption process. A methodology to find optimal process condition and solvent has been developed using an advanced equation of state (SAFT-VR), process modelling-optimisation software (gPROMS), and detailed process cost estimation...

Corrosion in CO2 Post-Combustion Capture with Alkanolamines – A Review — CO2 capture and storage plays an important part in industrial strategies for the mitigation of greenhouse gas emissions. CO2 post-combustion capture with alkanolamines is well adapted for the treatment of large industrial point sources using combustion of fossil fuels for power generation, like coal or gas fired power plan...

Reversible CO2-induced precipitation of a calix[4]arene-based complex leads to selective separation of Na+ salts.

Efficient reduction of CO2 into useful carbon resources particularly CO is an essential reaction for developing alternate sources of fuels and for reducing the greenhouse effect of CO2. The binuclear Ni, Fe-containing carbon monoxide dehydrogenase (CODHs) efficiently catalyzes the reduction of CO2 to CO. The location of Ni and Fe at proper positions allows their cooperation for CO2 to CO conver...
