Conversion of Glycerine to Synthesis Gas and Methane by Film Boiling

Abstract: This paper presents a new approach for promoting thermal decomposition reaction of subcooled liquids. It is based on establishing film boiling of the liquid. The process is illustrated by converting aqueous glycerine to synthesis gas (a mixture of carbon monoxide and hydrogen) and methane. A horizontal tube is immersed into a pool of aqueous glycerine (water weight fractions of 3% and 10%) and film boiling is established on the tube. Because of the large temperature drop that occurs across the vapor film that … Show more

“…Various possibilities are being studied and assessed to find a suitable utilization of excessive glycerin. The most promising options are its employment as an environmentfriendly solvent with reduced global warming potential [10][11][12][13] or its transformation to other valuable chemicals [14][15][16]. Distillation of binary and ternary mixtures of glycerin is a common process which is applied during extractive distillation of ethanol [8,10,17], purification of crude glycerin [15,18], or absorption of ethanol from gaseous mixtures of ethanol and CO 2 [17].…”

“…Pure or even crude glycerin might be fermented to valuable products like 1,3-Propanediol [5]. Catalytic conversion or pyrolysis to other valuable chemicals such as syngas is also possible [6,7]. However, in order to find reasonable applications, the behavior of glycerin in various apparatuses and conditions have to be thoroughly studied and described together with its thermophysical, chemical and transport properties.…”
