Abstract The inevitable depletion of fossil resources and the resulting anthropogenic climate change require a shift towards renewable feedstocks eco‐friendly technologies for greener energy, fuel, chemicals production. This mini‐review highlights our relevant research contributions to advance production carbon‐neutral propylene, 1,2‐propanediol biohydrogen through thermo‐chemical conversion biomass‐derived glycerol, using various heterogeneous catalysts. These achievements, recently recognized by “ ACI/NBB Glycerine Innovation Award ,” are organized into shared sections: (i) economic environmental benefits utilizing surplus bioglycerol, as feedstock, (ii) strategies improve properties transition metals‐based catalysts (e.g., Pt, Pd, Ni, Cu or Mo supported on γ‐Al 2 O3 SiO ) glycerol via: steam reforming, aqueous‐phase hydrogenolysis, hydrodeoxygenation reactions, (iii) discussion catalytic roles metallic, acidic and/or redox sites, keys factors affecting catalyst stability selectivity in these reactions operated under H O‐rich conditions, (iv) assessment reaction configurations operating conditions improved target product, utilization efficiency CO emissions. insights aim guide continuous improvement bioglycerol upgrading processes.
