Selective process modifications were considered among the possible process variations for carbon dioxide separation in natural gas fired combined gas and steam turbine power plants that differ greatly among themselves in terms of additional expense (effici ...
The atmospheric concentration of CO 2 increased from 190 to 280 ppm between the last glacial maximum 21,000 years ago and the pre-industrial era. This CO 2 rise and its timing have been linked to changes in the Earth's orbit, ice sheet configuration and vo ...
Current and future dynamics, of environmental legislations and trading market, of the fuel and electricity prices due to the market liberalization or resource shortages, and of the innovations of power/cogeneration technologies, impose great challenges on ...
In order to mitigate climate change, the countries that ratified the Kyoto protocol agreed to lower their greenhouse gas emissions during the period 2008-2012 of 5% on average compared to their emissions of 1990. Carbon separation and storage (CSS) process ...
Phosphate accumulating organisms (PAO) and glycogen accumulating organisms (GAO) play an important role in aerobic granular biofilm systems used for wastewater treatment. Both are slow growing organisms which can take up and store carbon under anaerobic co ...
We present analyses of new and previously published estimates of total (vegetation plus soil) carbon storage on exposed continental shelves during the LGM. Carbon stock estimates from environmental reconstructions vary from 113 to 202 Pg C. Estimates from ...
Methane (CH4) is a major greenhouse gas whose global warming potential is 23 times more important than carbon dioxide (CO2). CH4 concentrations have steadily increased since the beginning of the industrial era, reaching an unprecedent level (almost 1800 pp ...
The catalytic decomposition of ozone (200-1600 ppm) to molecular oxygen was investigated over activated carbons in the form of woven fibre fabrics (ACF) or granules (ACG) at room temperature. The dynamics of carbon activity was characterised by two distinc ...
There has been growing concern about the way cultivating biomass for the production of agro-biofuels competes with food production. To avoid this competition biomass production for biofuels will, in the long term, have to be completely decoupled from food ...
Growing peatlands are an important long-term carbon (C) sink and thus play a key role in the global C cycle. Vast surfaces of northern peatlands have been mined for peat and are currently abandoned. In these surfaces, secondary vegetation succession takes ...
