Biomass and coal gasification is a rapidly developing technology due to the increasing global demand for fossil fuel resources. Gasification is the process of conversion of solid carbonaceous feedstock to a gas mixture containing CO and H2 in the presence of steam or carbon dioxide. Past research on coal gasification has shown that the process requires high temperatures (> 800 oC) and produces ...
We describe atmospheric validation of 1:61 mm and 2:06 mm CO2 absorption coefficient databases for use by the Orbiting Carbon Observatory (OCO-2). The OCO-2 mission will collect the measurements needed to estimate column-averaged CO2 dry air mole fraction within 1 ppm accuracy without the regionor airmass-dependent biases that would significantly degrade efforts to understand carbon sources and...
Carbon dioxide (CO2 ), as the primary greenhouse gas in the atmosphere, triggers a series of environmental and energy related problems in the world. Therefore, there is an urgent need to develop multiple methods to capture and convert CO2 into useful chemical products, which can significantly improve the environment and promote sustainable development. Over the past several decades, metal-organ...
The availability of atmospheric carbon dioxide is the sine qua non for all plant growth and thence for all marine and terrestrial life forms. The purpose of this paper is to show that proposed reductions in anthropogenic emissions of carbon dioxide (CO2) to below the level of observed annual incremental biospheric absorption of those emissions would reduce the growth of the basic feedstock of a...
As high CO2-emitting utilities and other industries move toward implementing carbon capture and storage (CCS) technologies to manage greenhouse gas emissions, more and more CO2 will become available as a resource for multiple applications. CO2 will be a plentiful potential feedstock (carbon source) for many products, including commercial chemicals, plastics, and improved cement. Unfortunately, ...
