Ethanol produced from lignocellulosic biomass of composition is not a new concept. However, the increase in the population and industrial activity in the world, the energy demand and environmental impacts brought to light the need for new energy sources. At the beginning of this new millennium, ethanol and biomass gained notoriety as sources that could sustainably complement the energy matrix and also to mitigate the impacts of fossil energy sources. There are different ways to produce ethanol from biomass, but the most studied technologies are those made through biotechnological routes. In view of the investments on development made over the years, this article aims at analyzing the generation of technologies in the main links of the second generation ethanol production chain through patent applications in order to identify trends that will guide the industry of this biofuel.
