The present invention related to a method of manufacturing a polycarbonate including the process of copolymerizing epoxide compound and CO2 using cobalt(III) or chromium(III), where the ligands contains at least 3 ammonium cations, central metal has formal −1 charge, and conjugated anions of ...
A formal approach to identify the parameters for which certain regimes are degenerate runs as follows. Suppose that T1=0 and Tz=Ty. It is shown in Appendix B.3 that in the interval (0,Tz) we have β−γx(t)−(ψ−δ(X(t)+αS0))=eρt(λx(t)+ζτ).The extraction rate...

Production MethodsCarbon monoxide is formed during combustion of carbonaceous materials in oxygen (when carbon is in excess), or it can be formed (with oxygen) by thermal decomposition of carbon dioxide (>2000° °C). It can be generated by improperly vented cooking and heating appliances includi...
However, to use carbon dioxide in a more benign and practical manner, efficient transformations with less- activated substrates under mild conditions have to be developed. Obviously, reactions of CO2 that require a high-energy input are not benign because in general this energy leads also to ...
This can be accomplished using the direct air capture of carbon dioxide, among other technologies. Process models of these systems assume that they would operate at standard ambient temperature and pressure, when capture rates vary with ambient conditions, including temperature, relative humidity, and ...
1. The term 'carbon' is typically used as a shorthand way of referring to greenhouse gases (GHGs), of which carbon dioxide is the main one produced by human activity. The GHGs incorporated within the EU ETS are: carbon dioxide, methane, nitrous oxide, perfluorocarbons, hydrofluorocarbon...
Methane Reduction and Carbon Dioxide Removal (CDR): There is an ever increasing focus on CDR. The IPCC WGIII Report has brought into even sharper focus the need for CH4 reduction and CDR. The McKinsey & Co led Frontier initiative is illustrative of both the awareness of the need, and the...
Abstract WE report here the photoelectrocatalytic reduction of carbon dioxide to form organic compounds such as formic acid, formaldeyde, methyl alcohol and methane, in the presence of photosensitive semiconductor powders suspended in water as catalysts. Photocatalytic reaction kinetics were elucidated ...
