We report on a facile and rapid microwave-assisted method for preparing a sodium-cadmium metal-organic framework (having coordinatively unsaturated sodium ions) that considerably shortens the conventional synthesis time from 5 days to 1 hour. The obtained (Na,Cd)-MOF showed an excellent volumetric CO2 adsorption capacity (5.2 mmol cm(-3) at 298 K and 1 bar) and better CO2 adsorption properties ...

Four types of synthetic sorbents were developed for high-temperature post-combustion calcium looping CO2 capture using Longcal limestone. Pellets were prepared with: lime and cement (LC); lime and flour (LF); lime, cement and flour (LCF); and lime, cement and flour doped with seawater (LCFSW). Flour was used as a templating material. All samples underwent 20 cycles in a TGA under two different ...

As part of DOE/NETL’s Carbon Sequestration Program, we are developing an integrated, multi-pollutant modeling framework to evaluate the costs and performance of alternative carbon capture and sequestration technologies for fossil-fueled power plants. The model calculates emissions, costs, and efficiency on a systematic basis at the level of an individual plant or facility. Both new and existing...

These are carbon capture and sequestra...

In the Nuon/Vattenfall CO2 Catch-up project, a pre-combustion CO2 capture pilot plant was built and operated at the Buggenum IGCC power plant, the Netherlands. The pilot consist of sweet water-gas shift, physical CO2 absorption and CO2 compression. The technology performance was verified and validated models were obtained. This paper describes the validation of a WGS reactor model and the excel...

Since there is no flue-gas desulfurization facility (FGD) in Australian Power Plants, the temperatures of flue gases from the plants range from 393–433 K which is much higher than the absorption temperatures in a typical post combustion CO2 capture (PCC) process. The additional cooling systems and equipments are required to cool flue gases. This adds to the cost, and water and energy consumptio...
