Resumen:

Before the extended use of fossil fuels, biomass was the main source of energy. Nowadays, there is an interest for its use in the production of different energetic materials, as well as added value substances. In order to obtain these products, biomass has to be transformed through different conversion process. Thermochemical biomass transformation presents an attractive option due to its ability to produce fuels quickly, along with the potential to decompose most biomass compounds, such as lignin. Hydrothermal processing (HTP) is a promising technology for being carried out at lower temperatures than pyrolysis and gasification and utilizing wet material up to 70% humidity content, saving biomass drying. However, one concern is that HTP typically uses fossil-generated electricity for heating. Therefore, to reduce its environmental impact, concentrated solar energy has been proposed as a heat source. In the present work, hydrothermal liquefaction of agave bagasse was performed in a solar furnace of 25kW. The experiments were carried out in a solar reactor specifically designed to work at maximum conditions of 220 bar and 500°C. The experiments were carried out with heating rate of 2°C/min. They considered different operational parameters of temperature (150, 250 and 300°C), initial pressure (10, 30 and 50 bar), residence time (0 and 60 min). The main results indicate that at lower temperatures of 250°C, a bio-oil with better energetic properties than that obtained by conventional pyrolysis at 450°C can be accomplished. © 2021.
