Comparisons of Alcohols Oxidation Comparison of simple alcohols containing only one hydroxide group is presented in Table 2 [135]: Table 2. Comparison of the properties of simple alcohols. Property Methanol Ethanol Oxidation OCP vs. RHE, V 0.1 0.11 Propanol Isopropanol 0.12 0.18 19.5 0 % CO2 in product stream (for stoichiometric water content) 87 27.4 The electrochemical activity of these alcohols to oxidize towards CO2 decreases in order: methanol, ethanol 1-propanol, 2-propanol. The largest gap is visible between methanol and ethanol, which probably reflects that the formation of CO2 from alcohols containing 2 or more carbon atoms requires the cleavage of at least one C–C bond. This thesis is strongly supported by the similar CO2 amounts obtained as a result of ethanol and 1-propanol oxidation, which both require breaking of one C–C bond, and the lack of CO2 present in the product stream for 2-propanol oxidation, which requires the breaking of 2 C–C bonds. Additionally, under prototype alcohol fuel cell conditions, the formation of the cor- responding aldehydes dominates ethanol and propanol oxidation. This is compatible with the view that aldehydes are formed via weakly adsorbed intermediates and that the strongly adsorbed intermediates are the precursors of carbon dioxide. In the case of methanol, the strongly adsorbed species constitute almost only CO and related species, whose oxidation probably proceeds more rapidly than the strongly adsorbed intermediates of ethanol and 1-propanol. This hypothesis explains the similarity between the oxidation of propanol and ethanol and why the water-to-methanol ratio in the feed stream strongly affects methanol oxidation. During C2 and C3, primarily alcohol C–C cleavage and the sub- sequent oxidation to CO2 are the most important factors influencing product distribution, while for methanol, where no C–C bonds must be broken, the amount of available water becomes the most important factor for product distribution. 5. Conclusions The development of new electricity production methods is one of the greatest chal- lenges humanity will face in the 21st century. Fuel cells are a concept that can be a solution to this problem. The use of low molecular weight alcohols as a fuel for such devices can be very convenient because they show not only high energetic densities but are also easy to store and transport. Their production streams are also well developed.PDF Image | Effect of Anode Material on Electrochemical Oxidation of Alcohols

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
