Solid Sorbents as a Retrofit Technology for CO2 Removal from Natural Gas Under High Pressure and Temperature Conditions

High-temperature removal of cadmium from a gasification flue gas using solid sorbents

Nitrogen enriched solid sorbents for CO2 capture

Reducing anthropogenic CO2 emissions to slow down the consequences of climate change concerns all developed countries. In the short term, one of the most viable options to cut down carbon emissions consists on CO2 capture and storage from large stationary sources such as power stations, cement plants, refineries, etc. The near-ready-to-use technology at this scale is amine scrubbing. However, i...

Stable solid and aqueous H2CO3 from CO2 and H2O at high pressure and high temperature

Carbonic acid (H2CO3) forms in small amounts when CO2 dissolves in H2O, yet decomposes rapidly under ambient conditions of temperature and pressure. Despite its fleeting existence, H2CO3 plays an important role in the global carbon cycle and in biological carbonate-containing systems. The short lifetime in water and presumed low concentration under all terrestrial conditions has stifled study o...

High-performance CO2 sorbents from algae

Highly porous N-doped carbon materials with apparent surface areas in the 1300 2400 m g range and pore volumes up to 1.2 cm g have been synthesized from hydrothermal carbons obtained from mixtures of algae and glucose. The porosity of these materials is made up of uniform micropores, most of them having sizes < 1 nm. Moreover, they have N contents in the 1.1 4.7 wt% range, this heteroatom being...
