Gasification of Lower Monohydric Alcohols by Solution Plasma Treatment and Its Reaction Mechanism

Solution plasma is a gas-phase discharge in the vapor bubbles in a solution and has the potential to efficiently produce H2 by decomposing aqueous alcohols. However, the mechanism of alcohol decomposition in solution plasma remains unclear. In this study, lower monohydric alcohols (methanol and ethanol, as well as 1- and 2-propanol) were treated in solution plasma, and in this paper, the gasification mechanism is discussed. The gases produced from these alcohols were mainly H2 and CO, with small ratios of C1–C3 hydrocarbons. Thus, the O/C ratio in the product gas was close to 1 for all alcohols, and most of the C atoms in the alcohols were bonded to O atoms. This excess of O atoms could have only come from water, suggesting a strong contribution of OH radicals from water for gasification. However, the C1–C3 hydrocarbons were produced solely by the decomposition of the alcohol. For both decomposition routes, possible reaction pathways are proposed that are consistent with the experimental facts such as the composition of the product gas and the intermediates detected.

Plasma–liquid systems are best recognised in biomedicine, where the generation of plasma‐treated water and complex organic‐containing solutions affords biological effects. However, plasma interactions with liquids are more diverse. In this review, we look from the chemical point of view at the three fields of plasma–liquid interaction in which plasma is used to convert organic substrates. In wastewater treatment, plasma decomposes organic substances: the selectivity towards specific products is less crucial than process energy costs. In the conversion of organic liquids for sustainable energy purposes, the carbon and hydrogen selectivity to syngas are important, but these are still destructive reactions yielding small molecules. Finally, we provide a comprehensive plasma application list for synthetic organic chemistry and discuss their mechanisms and limitations.
