Synergestic effect in the steam co-gasification of olive pomace, coal and petcoke: Thermogravimetric-mass spectrometric analysis

A comparison of the gasification performance of olive pomace, coal, petcoke and their binary and ternary blends was carried out by means of TGA (thermogravimetric analysis) coupled with mass spectrometry (MS). The thermochemical behavior of the raw materials was a function of their composition and i...

The thermochemical behavior of the raw materials was a function of their composition and inorganic content. Olive pomace had a low ash content, a high volatile content and a low moisture. Moreover, olive pomace presented the highest reactivity. On the other hand, olive pomace presented the highest H2, CO, CO2, CH4 and NO emissions, while the highest SO2 release was obtained with petcoke, showing the output stream coming from the gasification of coal the highest H2/CO ratio. The presence of olive pomace in the blends improved their reactivity, increased the H2 release and the H2/CO ratio, and decreased the CO yield. A synergistic effect was observed in the gasification of the binary blend of olive pomace and petcoke. On the contrary, the gasification of the binary blend of olive pomace and coal presented an antagonistic effect. In ternary blends, either ssynergistic or antagonistic effects were observed, which depended on raw materials ratios in the feed. Finally, the lower the olive pomace ratio in the blends, the higher the porosity of the remaining residue was.Se llevó a cabo una comparación del rendimiento de gasificación de orujo de oliva, carbón, coque de petróleo y sus mezclas binarias y ternarias mediante TGA (análisis termogravimétrico) acoplado a espectrometría de masas (MS). El comportamiento termoquímico de las materias primas estuvo en función de su composición y contenido inorgánico. El orujo de aceituna presentó un bajo contenido de cenizas, un alto contenido de volátiles y una baja humedad. Además, el orujo de oliva presentó la mayor reactividad. Por otro lado, el orujo de aceituna presentó las mayores emisiones de H 2 , CO, CO 2 , CH 4 y NO, mientras que la mayor liberación de SO 2 se obtuvo con el coque de petróleo, siendo el flujo de salida procedente de la gasificación del carbón el mayor H 2relación /CO. La presencia de orujo de aceituna en las mezclas mejoró su reactividad, aumentó la liberación de H 2 y la relación H 2 /CO, y disminuyó el rendimiento de CO. Se observó un efecto sinérgico en la gasificación de la mezcla binaria de orujo de oliva y coque de petróleo. Por el contrario, la gasificación de la mezcla binaria de orujo de aceituna y carbón presentó un efecto antagónico. En las mezclas ternarias, se observaron efectos sinérgicos o antagónicos, que dependían de las proporciones de las materias primas en la alimentación. Finalmente, cuanto menor era la proporción de orujo de oliva en las mezclas, mayor era la porosidad del orujo restante.Elsevier202220222018info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29759reponame:RUIdeRA.
