Pathway of carbon dioxide reduction to acetate without a net energy requirement inClostridium purinolyticum

Reduction of carbon dioxide in 1-butyl-3-methylimidazolium acetate.

Gaseous CO(2) is almost irreversibly absorbed by the room temperature ionic liquid 1-butyl-3-methylimidazolium acetate ([C(4)mim][Ac]) in which it undergoes a chemically irreversible, one electron electrochemical reduction, suggesting a means for the sequestration of the greenhouse gas.

Energy Policies for Carbon Dioxide Emission Reduction

The carbon dioxide requirement of Neisseria gonorrhoeae.

In some microorganisms C02 can be replaced successfully as a growth factor by certain dicarboxylic acids which enter the Krebs cycle (Lwoff and Monod, 1946; Ajl and Werkman, 1948). Other microorganisms require C02 for growth even when cultivated on rather complex media (Steinman, et al., 1954; Mueller and Einton, 1941), and the biochemical basis for this need has remained obscure. In the course...

Exergy and Energy Analysis of Effective Utilization of Carbon Dioxide in the Gas-to-Methanol Process

Two process models are used to convert carbon dioxide into methanol. These processes have been extended and improved using Aspen Plus simulator software. Both processes are found in the CO2 correction system. In this machine, the desired synthesis gas is produced in a flexible configuration. At the same time, the conversion of CO2 to hydrogen via a copper-based catalyst ha...
