Zn(NH3)(CO3) inorganic helical framework for selective separation of carbon dioxide

Independent Colimitation for Carbon Dioxide and Inorganic Phosphorus

Simultaneous limitation of plant growth by two or more nutrients is increasingly acknowledged as a common phenomenon in nature, but its cellular mechanisms are far from understood. We investigated the uptake kinetics of CO(2) and phosphorus of the algae Chlamydomonas acidophila in response to growth at limiting conditions of CO(2) and phosphorus. In addition, we fitted the data to four differen...

Synthesis of Layered Metal Organic Frameworks for Carbon Dioxide Separation *

Current rising atmospheric CO2 concentration and its potential dramatic influence on climate change have led to intensive research into materials for CO2 capture and separation , since CO2 capture and storage (CCS) is anticipated to be an important component of reducing worldwide CO2 emissions from stationary point sources, such as coal-fired power plants . In this work, we focus on the potenti...

Novel Ceramic Membrane for High Temperature Carbon Dioxide Separation

A High Pressure Carbon Dioxide Separation Process for IGCC Plants

Under separate contracts from the U.S. Department of Energy, Office of Fossil Energy (DOEFE), Los Alamos National Laboratory, and a team of SIMTECHE and Nexant (a Bechtel Technology and Consulting Company) are jointly working to develop the proprietary process for capturing carbon dioxide (CO2) from a shifted syngas stream (a mixture of mostly carbon dioxide and hydrogen) prior to combustion in...

Kinetic separation of carbon dioxide and methane on a copper metal-organic framework.

Separation of carbon dioxide and methane is an important issue in upgrading low-quality natural gas. Adsorption equilibria and kinetics of CO(2) and CH(4) on a copper metal-organic framework (MOF), Cu(hfipbb)(H(2)hfipbb)(0.5) [H(2)hfipbb=4,4'-(hexafluoroisopropylidene) bis(benzoic acid)], were investigated to evaluate the feasibility of removing CO(2) from CH(4) in a pressure swing adsorption p...
