Carbon dioxide as the working fluid in heating and/or cooling systems [PDF]

, 2003
Despite vigorous research the use of carbon dioxide in the market is still relatively small. This is due to legislation, and technical difficulties of developing efficient, acceptable carbon dioxide ...

Automation of Bosch reaction for CO2 reduction [PDF]

, 1972
System for collecting excess carbon dioxide in space cabin is described. System collects carbon dioxide exhaled by human inhabitants and decomposes gas into carbon and water by reaction with hydrogen in presence of catalyst. Diagram of equipment involved

Subtle tuning of micro-environment in COFs nanoribbons actuates low electricity-consumption photo-assisted Co-electrolysis of methanol and CO2

Nano Research Energy
The lower electricity consumption (EC) and higher value-added products are much desired yet still challenging for the development of CO2 coupling electrocatalytic systems.

Comparison of data-driven uncertainty quantification methods for a carbon dioxide storage benchmark scenario

, 2018
A variety of methods is available to quantify uncertainties arising with\-in the modeling of flow and transport in carbon dioxide storage, but there is a lack of thorough comparisons.

Climate simulation of the latest Permian: Implications for mass extinction [PDF]

, 2005
This report presents the results of climate modeling research which indicates that elevated levels of carbon dioxide in the atmosphere at the end of the Permian period led to climatic conditions inhospitable to both marine and terrestrial life.

Exploring Non-aqueous Solutions for CO2 Capture at Elevated Pressure: An Initial Study for EHA/MOR in DMSO Mixtures [PDF]

E3S Web of Conferences
Carbon dioxide (CO2) absorption in a non-aqueous solution is a potential technology for reducing greenhouse gas emissions. In this study, a non-aqueous solvent, dimethylsulfoxide (DMSO), was blended with a amines The non-aqueous blended amines absorbents’

Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]

, 2002
Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation

A new simulation approach for hydraulic fracture network of deep coalbed methane reservoirs with equivalent parameter method

Energy Exploration & Exploitation
Cleat systems are widely distributed within deep coalbed methane (CBM) reservoirs. The significant uncertainty regarding the distribution and density of these cleat systems complicates accounting for their impact on hydraulic fracture propagation.

Nonsmooth frameworks for an extended Budyko model

, 2017
In latitude-dependent energy balance models, ice-free and ice-covered conditions form physical boundaries of the system. With carbon dioxide treated as a bifurcation parameter, the resulting bifurcation diagram is nonsmooth with curves of equilibria and ...
