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 surrounds the tube, the potential exists to drive pyrolytic or thermal cracking reactions at high temperature but in a comparatively cold bulk liquid. The reaction products are transported away from the tube under the action of buoyancy. The reactor volume essentially forms by itself solely as a result of heating the tube.
