Combustión de biomasa sin emisión de CO2 en una planta de 20 kW

Abstract

El Acuerdo de París fijó el objetivo de limitar en 2 ºC el incremento de temperatura media global sobre los valores preindustriales. Para tal efecto, el IPCC señala a la bioenergía con captura y almacenamiento de CO2 (BECCS en inglés) como una de las tecnologías clave para reducir el impacto del cambio climático pudiendo alcanzarse emisiones negativas de CO2. La implementación de biocombustibles en las tecnologías tradicionales de captura de CO2 implica un alto coste energético del combustible obteniendo una corriente de CO2 prácticamente puro con uno de los menores costes energéticos asociados. El proceso se basa en la utilización de un transportador de oxígeno (TO), normalmente un óxido metálico, que al transportar el oxígeno del reactor de oxidación al de reducción, evita la mezcla del oxígeno del aire y los gases de combustión, evitando de este modo la aplicación de un proceso de separación de gases. En este trabajo se evaluó en una planta piloto de 20 kW de potencia, el efecto de las principales variables de operación bajo condiciones de In situ Gasification-CLC como son la circulación de sólidos, el tipo de agente gasificante y el inventario específico de sólidos en el reactor de reducción sobre los principales parámetros de rendimiento del proceso como son la eficacia de captura de CO2 y la demanda total de oxígeno.

Trabajo financiado por el MINECO (ENE2014-56857-R, ENE2016-77982-R, ENE2017-89473-R) y por FEDER. A. Pérez-Astray agradece la beca predoctoral BES-2015-074651.
