Resumen:
The transformation of glycerol, by-product of the biodiesel production, has awaken some interest because of its growing production from the biofuel production process and because its origin from renewable raw materials, which allows it to be obtained in a sustainable environmental development. Reactions to produce compounds of commercial interest and added value, such as hidrogenolysis to propanediols, etherification to ethers of glycerol, are being focused now for study. The main objective is to design the adequate catalysts for these processes and to select the corresponding operational conditions. The Pt/WO3/ZrO2 catalytic system was recently reported as an active system for the glycerol hidrogenolysis, thus producing mainly the 1,3-propanediol, though the 1,2-propanediol or propylenglycol were also formed. The experience in both preparation and characterization of that catalyst was the starting point in order to study the hidrogenolysis reaction, including preparation parameters of WO3/ZrO2 and the metal precursor used, in order to control the reaction selectivity and thus optimize the propanediol production. Then, the etherification of glycerol with isobutylene was studied, starting from reports of using acidic ion-exchange resins, while a second catalyst such as supported metals, which generate a synergistic effect and promote their catalytic behavior. The reforming of glycerol is another interesting reaction, as it allows to obtain hydrogen, which is considered the future renewable fuel. This reaction takes place on 8-10 metal groups supported catalysts. The comparison between catalytic and biologic ways to transform the glycerol is important to make a complete evaluation previously to scaling-up the process. A complete review of the mentioned reactions including the catalysts used was made.
