Biomass pyrolysis liquids. Fundamentals, technologies and new strategies.

Abstract

[ES] Los líquidos de pirólisis de biomasa son productos prometedores obtenidos a partir de recursos renovables que pueden ser utilizados para la producción de compuestos químicos valiosos, combustibles y energía. De cara a maximizar el rendimiento a productos líquidos, las tecnologías de pirólisis más adecuadas son aquellas basadas en la pirólisis rápida (“fast pyrolysis”). Estas tecnologías se caracterizan por unos tiempos de residencia cortos tanto de los sólidos como de los gases y vapores, muy altas velocidades de calentamiento y temperaturas de operación en el intervalo entre 450 y 550 ºC. Las aplicaciones a escala comercial para estos líquidos todavía presentan algunos retos que precisan ser solventados. No obstante, existen ya casos exitosos de desarrollos de tecnologías de pirólisis rápida a escala industrial, en los que se obtienen bien productos químicos o energía mediante combustión del líquido de pirólisis. En este contexto, se pueden proponer estrategias novedosas de cara a la integración de procesos y la valorización de subproductos y corrientes residuales. Siguiendo esta concepción, existen actualmente distintos esquemas de biorrefinería que tienen como objetivo la producción de toda una serie de bioproductos con alto valor añadido junto con la tradicional producción de bioenergía

[EN] Biomass pyrolysis liquids are promising for the production of valuable chemicals, fuels and energy from renewable resources. Fast pyrolysis technologies are selected for maximizing the yield to liquid products, being characterized by short residence times for solids and vapors, very high heating rates and operating temperatures typically in the range of 450-550 ºC. The applications for these liquids at a commercial scale still present some challenges that need to be solved. Nonetheless, there are already successful cases of fast pyrolysis technologies at full scale, yielding chemicals or producing energy via combustion of the liquid. New strategies can be proposed for developing integration of processes and valorization of byproducts and residual streams in the fast pyrolysis process. Following this approach, different biorefinery schemes have already been proposed aiming at producing different biobased products with higher added value apart from bioenergy.

The authors express their gratitude to the Spanish Ministry of Science and Innovation MICINN (Research Project Ref. Num. CTQ2010-19811 and CTQ2010-20137), the Gobierno de Aragon and the European Social Fund for providing financial support for the work.
