The current growth of the biodiesel industry, that satisfies part of the global energy demand, also generates a high proportion of crude glycerol, becoming an environmental problem as it is accumulated and not commercialized. This study evaluates the catalytic potential of Colombian olivine, using glycerol steam reforming to appraise valorization alternatives for this subproduct. The olivine analyzed was thermally treated at 1200 °C and reduced at 900 °C. The calcined olivine increased glycerol conversion at 600 °C from 58% (without catalyst) to 97% with the formation of liquid-phase products. By another way, syngas with H2/CO ratios of 1.1 and 1.5 was generated with reaction temperatures of 700 and 800 °C, respectively, with low contents of CH4. Finally, it was established that the Medellín olivine, under the used conditions for glycerol steam reforming, represents a viable and interesting alternative to valorize glycerol toward gas-phase or liquid-phase products.
