Abstract:
The research to date on renewable ethanol is focused on ethanol production from biomass via biological (1st generation) or biochemical (2nd generation) pathways, and frequently the term bioethanol in used only to refer them. However, it must be used in a broadest sense to refer to whatever ethanol produced by a process using biomass as feedstock. Up to date, 2nd generation processes could be classified in three broad pathways: biochemical (enzymatic hydrolysis), bio-thermochemical (fermentation of synthesis gas) and thermochemical (catalytic synthesis). The aim of this paper is to present a short review on the state of the art of 2nd generation processes to produce ethanol from lignocellulosic biomass. In this short review, especial attention is taken for the thermochemical pathway, probably the most promising and unknown pathway.
