Carbon dioxide reduction product distribution

However, there are several issues with widespread methanol usage. Methanol production from natural gas is relatively inefficient ( 67%), and this largely offsets the vehicular improvement in efficiency and carbon dioxide reduction (since gasoline can be made with "85% efficiency from oil). Additionally, the PEM fuel cell demands very pure methanol, which is difficult to deliver using existing oil pipelines and may require a new fuel distribution infrastructure. 

To study the effect of the Ru/Al Oj catalyst on hydrogen yield for refomung of glucose in supercritical water, the experiments were compared to reactions with and without catalytic runs imder identical conditions. Typical product distributions are shown in Table 6.9 for experiments with and without a Ru/Al Oj catalyst at 973 K with 1 wt.% glucose feed (Byrd et al., 2007). There was a significant reduction in carbon monoxide and methane yields in the presence of the catalyst. The main products of the reaction were hydrogen, methane, carbon dioxide, and carbon monoxide. The low carbon monoxide yield (0.1% by vol.) indicates that the water-gas shift reaction approaches completion. 

In the work of WRAP (Final Report, 2012 Dynamics), eco-efficiency across the supply chain of textile and clothing product consumption in the UK over one year is analyzed, consisting only of the production, distribution, and retailing phases. It is seen that in the baseline scenario a 4.1% reduction on current carbon dioxide emission is possible and if the highest possible reduction scenario occurs, the rate of reduction is estimated as 24.5%. Detailed information about the estimation of reduction in sector-based supply chain carbon dioxide emission in the UK can be found in the report. 

The increase of carbon dioxide in the atmosphere is of global environmental interest due to the greenhouse effect. Thus accurate analysis of carbon dioxide is of environmental importance. The distribution of products obtained on electrocat-alyzed reduction of CO2 on M-N4 complexes, depend of factors such as applied potential, pH, nature of macrocycle and the nature of the central metal. 

The electrochemical activation of carbon dioxide is intensely investigated as a possible means of converting this rather inert molecule into useful chemicals. Direct electrochemical reduction on most metal electrodes suffers from a large overpotential and an extreme dependance of product distribution both on the nature of the electrode material and of the reaction medium [1], Efficient reduction requires catalysis. A large number of transition metal complexes has been successfully used as catalysts for CO2 reduction, mainly to CO and formic acid [2], Electrogenerated organic anion radicals have also been shown to give efficient catalysis of CO2 reduction to oxalate [3].
