Olive Waste Valorization Through TGA-MS Gasification: A Diatomaceous Earth Effect

The effect of diatomaceous earth on gasification of olive pomace and olive stone was studied by thermogravimetric analysis with mass spectrometry (TGA-MS). Additionally, gas emissions, the H2/CO ratio, and gasification reactivity were evaluated. First, a preliminary study of the effect of particle s...

Additionally, gas emissions, the H2/CO ratio, and gasification reactivity were evaluated. First, a preliminary study of the effect of particle size on olive waste gasification was performed to select the most appropriate from a technical and industrial point of view. With olive pomace, the larger the particle size, the lower H2/CO and reactivity. However, with olive stone, optimum results were observed with the largest particles. Subsequently, olive waste was mixed with different percentages (10, 25, and 50 wt %) of diatomaceous earth. When olive pomace contained diatomaceous earth, even though there was no substantial improvement in reactivity, syngas quality in terms of H2/CO was significantly enhanced and increased by up to four times. However, the diatomaceous earth effect on olive stone gasification was more remarkable, enhancing both reactivity and the H2/CO ratio. Different behaviors in the biomasses were due to the different impacts of the alkali and alkaline earth metals on the diatomaceous earth. Whereas both of these made positive contributions to the olive stone, only the latter had a significant influence on olive pomace.El efecto de la tierra de diatomeas sobre la gasificación del orujo de aceituna y del hueso de aceituna se estudió mediante análisis termogravimétrico con espectrometría de masas (TGA-MS). Adicionalmente se evaluaron las emisiones de gases, la relación H 2 /CO y la reactividad de gasificación. En primer lugar, se realizó un estudio preliminar del efecto del tamaño de partícula en la gasificación de los orujos para seleccionar los más adecuados desde el punto de vista técnico e industrial. Con orujo de oliva, cuanto mayor es el tamaño de partícula, menor H 2/CO y reactividad. Sin embargo, con el hueso de aceituna se observaron resultados óptimos con las partículas más grandes. Posteriormente, los orujos se mezclaron con diferentes porcentajes (10, 25 y 50 % en peso) de tierra de diatomeas. Cuando el orujo de oliva contenía tierra de diatomeas, aunque no hubo una mejora sustancial en la reactividad, la calidad del gas de síntesis en términos de H 2 /CO mejoró significativamente y aumentó hasta cuatro veces. Sin embargo, el efecto de la tierra de diatomeas sobre la gasificación del hueso de aceituna fue más notable, mejorando tanto la reactividad como el H 2relación /CO. Los diferentes comportamientos en las biomasas se debieron a los diferentes impactos de los metales alcalinos y alcalinotérreos sobre la tierra de diatomeas. Mientras que ambos hicieron contribuciones positivas al hueso de aceituna, solo el último tuvo una influencia significativa en el orujo de aceituna.American Chemical Society202220222021info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29908reponame:RUIdeRA.
