“…However, the result compared to the overall exergy efficiency of an oil extraction process from microalgae (51%) [16], and a palm biorefinery (38%) [17], is lower which suggests that improvements should be implemented to optimize the process, especially, alternatives to make use of palm rachis and palm fibers. Studies suggest that palm fibers can be used to improve the mechanical properties of panels [18], while rachis can be used for obtaining synthesis gas [19], hydrogen production [17,20], biodiesel production [21], and in the biosorbent preparation for uptaking Cd(II) and Ni (II) [22].…”

Palm production chains in Colombia have some unsatisfied demands that affect their competitiveness. Specific demands include efficiency in energy use. Therefore, in the present report, an exergy analysis for the dual crude palm and kernel oil production process was carried out to determine the main energy sinks and suggest technological improvements that allow better use of energy. For this study, the process was initially simulated in the Aspen Plus ® software, where the chemical and physical exergies of the species and streams involved were quantified. The process irreversibilities, the exergy loss, the exergy of waste, and the exergy of utilities were calculated for each stage and the whole process. An overall exergy efficiency of 18% was achieved, while the highest process irreversibilities contribution was due to the destroyed exergy with the waste in the threshing stage. To increasing the global exergy efficiency of dual crude palm and kernel oil production, it is proposed the evaluation of palm rachis use to obtain biofuels and/or high-value products.

Enhancement of Cadmium Adsorption Capacities of Agricultural Residues and Industrial Fruit Byproducts by the Incorporation of Al₂O₃ Nanoparticles

In this work, two types of residues (industrial fruit byproducts and agricultural wastes) were studies as promising adsorbents for cadmium uptake. Adsorption experiments using the evaluated biomasses (corn crops CC, palm bagasse PB, orange peels OP, and lemon peels LP) were conducted in batch mode by varying initial solution pH (2, 4, and 6) as well as the particle size (0.355, 0.5, and 1 mm). The optimum operating conditions were defined for further adsorption tests. The biomasses were chemically modified with alumina nanoparticles to evaluate the enhancement in adsorption capacities and how the nature of biomass contributes to successful incorporation of nanotechnology-based materials. The point of zero charges was ranged between 4 and 5 for all biomasses. Simultaneously, the Böehm titration method confirmed the presence of lactonic and carboxylic acid groups on the surfaces of the biomasses. Optimum operating conditions for batch cadmium adsorption experiments were observed at pH 6. Moreover, no significant changes were detected as a function of biomass size. For corn cob and lemon peels, removal percentages at 86 and 88% were reached using particle size = 0.5 mm. For palm bagasse and orange peels, the optimum parameters were 0.355 and 1 mm, respectively. Al 2 O 3 nanoparticles with a crystal size of 58 ± 12 nm were obtained by applying the sol–gel methodology. A higher cadmium removal percentage was detected after using the biomasses modified with the Al 2 O 3 nanoparticles, determining for the agricultural wastes an adsorption capacity of 91% (CC-Al 2 O 3 ) and 92% (PB-Al 2 O 3 ). In comparison, the industrial fruit byproducts exhibited a removal percentage of 93% (LP-Al 2 O 3 ) and 96% (OP-Al 2 O 3 ). The modification of industrial fruit byproducts (lemon peels and orange peels) showed increases in adsorption efficiencies around 12–6% after incorporating alumina nanoparticles, suggesting that this type of biomass is more suitable for adsorption property enhancement using nanomaterials.

“…Los valores de qm alcanzados al emplear las cáscaras de arroz natural y activada químicamente (CA-KOH y CA-H3PO4) fueron comparables con los resultados registrados en la bibliografía para otros biosorbentes (Abdolali et al, 2015, Velazquez-Jimenez et al, 2013, Alexander et al, 2017, Nag et al, 2018, Herrera-Barros et al, 2020, Peng et al, 2018, Romano et al, 2020. Si bien, para algunos residuos las capacidades de sorción máxima fueron superiores a las reportadas en este trabajo, no es posible efectuar una comparación rigurosa puesto que, en muchos casos, las condiciones de los ensayos de sorción variaron según el biomaterial empleado.…”

La contaminación por metales pesados constituye uno de los mayores riesgos para los cursos de agua ya que estos tóxicos son de difícil eliminación dada su naturaleza no biodegradable y persistente. Numerosas tecnologías han sido desarrolladas para tratar esta problemática ambiental, siendo la biosorción una de las alternativas más utilizadas debido a su eficiencia, bajo costo y posibilidad de utilizar materiales naturales como biosorbentes. Los residuos agrícolas constituyen una fuente importante de biomasa que puede ser empleada en este tipo de procesos. Por ello, el objetivo del presente estudio fue analizar los factores fisicoquímicos que afectan la sorción de zinc en solución empleando como biosorbente cáscara de arroz natural o modificada químicamente con hidróxido de potasio o ácido fosfórico. Este es un residuo altamente disponible en la provincia de Entre Ríos, Argentina.Los sorbentes fueron caracterizados por espectroscopía infrarroja y mediante la determinación del pH en el punto de carga de cero.El tratamiento químico con hidróxido de potasio mejoró significativamente la remoción del contaminante, mientras que la activación ácida no arrojó mejoras respecto al uso de la cáscara natural. Los niveles de remoción se favorecieron al incrementar el pH hasta 5 y la dosis del biosorbente, mientras que disminuyeron al aumentar la concentración de adsorbato.Para los sistemas evaluados el equilibrio del proceso se alcanzó rápidamente, ajustándose a una cinética de pseudo-segundo orden. Para los biosorbentes empleados se presentaría una sorción en monocapa con sitios de unión homogéneos.
