Low-temperature catalytic decarboxylation of formic and acetic acid over a Ru/TiO2 catalyst: prospects for continuous production of energy-rich gaseous mixtures

Abstract

Catalytic decarboxylation is a novel and promising pathway for continuous and efficient conversion of organic wastewaters. Stable conversion of acetic acid to CH₄ and CO₂ mixtures (T ≥ 225 °C, S_p > 80%, 70 h TOS) was demonstrated. Approaches for overcoming catalyst deactivation during production of H₂-rich gas from formic acid are outlined.
