Sustainable production of allyl alcohol

Allyl alcohol is an industrially important substance, mostly used for the production of chemical intermediate in organic synthesis. Current industrial processes for the production of allyl alcohol are fossil fuel-based routes from hydrogenation of propylene-derived acrolein or propylene oxide isomerization. In addition, the allyl alcohol can be produced by the catalyzed acetoxylation of propylene over noble metal catalysts. All these methods have many disadvantages such as environmentally unfriendly route, multistep synthesis, unsustainable process, expensive and toxic feedstocks. These disadvantages in the current industrial processes have stimulated researchers to develop new sustainable routes for production of allyl alcohol from glycerol.
Nowadays, there is no industrial process for the large-scale production of allyl alcohol from glycerol. The market size of allyl alcohol is 0.1 Mt/year with price 2.2-3.2 USD/kg, making it much more commercially attractive in comparison to glycerol (0.1-0.6 USD/kg).


The present invention relates to the use of a tri-metallic promoted aluminosilicate zeolite catalyst for the direct gas-phase conversion of glycerol to allyl alcohol, as well as to a process for the production of allyl alcohol from glycerol in a fixed-bed continuous flow reactor in the presence of such heterogeneous catalysts. The method comprises conversion of glycerol to allyl alcohol in the range of temperature 250-450 °C, glycerol concentration 1-60 wt %, total gas hourly space velocity 100-2000 h-1, the weight of catalyst 0.5-5.0 g.
