“…However, it can be noted that the highest oil conversion (60%) was achieved with the use of the CaO/SiO 2 composite with aratio of CaO to SiO 2 of 1:1. Based on these results, it should be noted that the oil conversion achieved in this study relatively lower compared to those reported by others for the same oil [20] [21]. In this respect, it should be acknowledged that more study is required to optimize the performance of the CaO/SiO 2 composites, in recognition of the higher performance of this catalyst reported by other works [3][19], together with the existence of the limestone and rice husk as low-cost raw materials.…”

In this study, CaO/SiO2 composites were prepared from rice husk silica (RH-SiO2) and limestone from a local company. The composites with different mass ratios of CaO to SiO2 (1:1, 1:2, 1:3, 1:5, and 1:10) were synthesized using the sol-gel technique and characterized using XRF, XRD, and SEM. The composites were then used as catalysts for the transesterification of palm oil, with the main purpose to investigate the effect of catalyst compositions on the percentage of conversion of the oil. The results of XRD and SEM confirm the existence of RH-SiO2 as an amorphous material, and CaO as crystalline material, while the composites are a mixture of amorphous and crystalline phases. The catalysts were then used in transesterification experiments and the percentage of oil conversion was calculated. To confirm the successful conversion of palm oil into fatty acid methyl esters, the products of the reactions were analyzed using GC-MS. The experimental results demonstrated that the composites prepared exhibit catalytic activity, with the highest conversion (60%) achieved using the catalyst with the CaO to SiO2 ratio of 1:3.

El objetivo fue evaluar el rendimiento de producción de biodiesel a partir de aceite de soja usado para un mejor aprovechamiento de los aceites usados por el método de transesterificación, se evaluaron el Óxido de Calcio (2 y 6%) y la Relación Molar de etanol: aceite (9:1 y 15:1). Se planteó un diseño experimental factorial 22 con cinco puntos centrales para evaluar el efecto de los parámetros relación molar etanol: aceite y el porcentaje de concentración de Óxido de Calcio en el rendimiento de biodiesel. El rendimiento mayor de biodiesel fue de 60.9%, con relación molar 15:1 etanol: aceite y concentración de óxido de calcio 6%. Cabe señalar que se podría optimizar este rendimiento aplicando la metodología de superficie respuesta, la viscosidad fue de 8,70 centistokes, resultado que estuvo cercano a la norma ASTM D6751-09. Por último, las variables de control con relaciones molares mayores a 15:1 y concentraciones de catalizador próximas al 6%, son aplicables para optimizar el rendimiento de producciones del biodiesel.
