The Ph.D. thesis of Aingeru Remiro-Eguskiza, a chemical engineer of the University of the Basque Country, deals with the quest for a process to produce hydrogen from bio-oil that has a lower impact on the environment than the process using current routes.
The gradual increase in the price of crude oil and the negative environmental consequences that its use entails are putting us on the threshold of a change of energy model that will need to be tackled over the coming decades. Faced with the obvious necessity of finding an energy alternative that will replace fossil fuels in the near future at least partially and in a gradual way, hydrogen is emerging as one of the alternatives.
Currently, hydrogen is obtained through various methods that require separating the hydrogen from other chemical elements like carbon (in fossil fuels) and oxygen (from water). The methods used for this purpose are not viable from an environmental or economic perspective, respectively, as far as the large-scale production of hydrogen is concerned.
The aim of this thesis was to contribute towards the laboratory scale development of a process for producing hydrogen from bio-oil by means of catalytic reforming using water vapour. Bio-oil is a heterogeneous mixture of wood-based oxygenated products, the catalytic transformation of which routinely entails problems of operability and deactivation of the catalyst. This is because when it is being heated, a fraction of the compounds that make up the bio-oil form a solid residue (the so-called pyrolytic lignin) which collects on the inlet pipes of the reactor and in the reactor itself. The bio-oil used for the research in the thesis was developed at an IK4-Ikerlan plant.
