Radioactive Carbon as an Indicator of Carbon Dioxide Utilization: VII. The Assimilation of Carbon Dioxide by Molds.

des Sciences Math6matiques," tome 1, volume 1, page 601, it is added that J. Perott used the term sulerien groups for abelian groups in American Journal of Mathematics, 11, 99 (1889). This matter is somewhat complicated by the fact that C. Jordan used the term abelian group, with a somewhat different meaning from that now commonly assigned to it, in his widely used "Trait6 des substitutions" (1...

Radioactive Carbon as an Indicator of Carbon Dioxide Utilization: VI. On the Possibility of Carbon Dioxide Reduction via the Carboxylase System.

Recent experiments,' carried out with the aid of labeled carbon, have shown beyond any doubt that CO2 enters into the metabolism of a large variety of organisms in the absence of light. As a consequence it has been suggested that CO2 assimilation may be a process of wide-spread occurrence in living systems. The metabolic processes of living organisms are for the most part enzyme catalyzed. The ...

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...

Carbon dioxide chemistry: Examples and challenges in chemical utilization of carbon dioxide*

The development of catalytic methods for chemical transformation of CO2 into useful compounds is of paramount importance from a standpoint of C1 chemistry and so-called green chemistry. The kinetic and thermodynamic stability of CO2 molecule presents significant challenges in designing efficient chemical transformations based on this potential feedstock. In this context, efforts to convert CO2 ...
