Abstract

Hydrothermal reaction of formic acid has been studied by varying the following conditions: temperature (275 to 350 °C), concentration of formic acid (0.1 to 1 M), addition of HCl, and presence of metal alloy powders. In hot water, formic acid decomposes to CO and CO<SUB>2</SUB>. The product ratio of CO to CO<SUB>2</SUB> strongly depends on the conditions. At higher concentrations and lower temperatures, the yield of CO gets larger. In most of the conditions studied here, the main product is not CO<SUB>2</SUB> but CO in contrast to previous works. Acid enhances the CO production and metal powders catalyze the decarboxylation pathway.
