“…Among the pecan biochars, the HB had the highest EC value, followed by the LB (0.83 mS/cm) and BB (0.81 mS/cm). This was consistent with the size order in the EC values of the Jatropha curcas leaf, branch, and trunk biochar [16]. As reported, the biochar with a high content of soluble cations tended to have an adverse effect on soil properties and plant growth [50].…”

“…The characteristics of biochars prepared from various organs or tissues of the same plant have also been compared. For example, the leaves, trunks, and branches of Jatropha curcas were used as materials for the preparation of biochar, and obvious differences in the biochar properties were revealed [16]. For the feedstock type to have an important effect on the properties and the application of biochar, it is essential to clarify the properties of biochars prepared with different raw materials in order to select suitable biochars for application [17,18].…”

Large amounts of residues are generated in pecan cultivation processes. Biochar is an environmentally friendly way to utilize residues but attempts to prepare and apply biochar with pecan residues are rare. In this study, six types of biochars were produced from pecan branches, trunks, roots, nutshells, husks, and leaves under pyrolysis, and their physicochemical properties were compared to assess their application perspective in environmental and agricultural fields. The yields of six pecan biochars were 32.1%–45.9%, with the highest yield for husk biochar (HB) (45.9%). Among the pecan biochars, trunk biochar (TB) and root biochar (RB) had much larger specific surface areas. Branch biochar (BB), TB, and RB presented tubular structures with elliptical pores, while nutshell biochar (NSB), HB, and leaf biochar (LB) appeared flaky or as clustered structures with relatively rougher outer surfaces and irregular pores. The functional group types of pecan biochars were generally similar, but the intensities of the peak near 2900 cm−1 in BB were obviously higher than those of the other biochars. RB and LB contained significantly more ash and volatile than those of the other pecan biochars, with the highest fixed carbon content being found in NSB (70.1%). All of the pecan biochars were alkaline (7.90–9.87), and HB, LB, and NSB had significantly higher pH values than those of the other biochars. Elemental analysis indicated that RB, NSB, and LB had higher carbon levels (more than 70%) with lower O/C ratios (no more than 0.2). HB possessed a relatively high content of nitrogen, potassium, magnesium; the phosphorus content was highest in NSB; LB had the highest calcium content. The results of principal component analysis showed that BB, LB, and NSB were clustered in the same quadrant with relatively close relationships. The results of this study can guide the utilization of pecan wastes and their application as biochar in different fields.

“…Biochar derived from wood residues are microporous, have high surface area, low ash, low moisture, and high stability due to the presence of lignin content and aromatic carbons whereas biochar from agricultural feedstocks contains more functional groups like hydroxyl, carboxyl and had better yield but low lignin content and thus it results in low stability (Pandey et al, 2020;Tomczyk et al, 2020;Xu et al, 2018). In a recent study, the leaves of a famous biodiesel plant named Jatropha curcas yielded 53.3 ± 9.2% biochar at 300 ⁰C pyrolysis temperature (Konaka et al, 2021). Agricultural feedstocks such as rice straw, rice husk, peanut shells provide a higher yield of biochar (Pandey et al, 2020).…”

“…Por otra parte, la conversión termoquímica de biomasa ha adquirido un mayor interés comercial frente a la conversión bioquímica, debido a su flexibilidad con diferentes calidades y más variedades de materia prima, su productividad relativamente más alta debido a la naturaleza completamente química de la reacción, su independencia de las condiciones del medio y operar a temperaturas superiores 14,15 . La cáscara del fruto de Jatropha curcas está reportada por varios autores como fuente de relativamente alto potencial energético para llevar a cabo procesos de conversión termoquímica como gasificación o pirólisis 12,[16][17][18] . La gasificación posee una eficiencia superior al generar electricidad y una gran capacidad de integración con otros sistemas productores de energía como ciclo de vapor, turbinas y motores a gas 19,20 .…”

La simulación de procesos desempeña un papel importante para el desarrollo de nuevas tecnologías y permite la asistencia en el diseño, operación y optimización de plantas. En la presente investigación se simularon mediante DWSim los procesos de transesterificación del aceite de Jatropha curcas y la gasificación de la corteza de su fruto. En la simulación del proceso de producción de biodiesel se emplearon cinco etapas: preparación del metóxido, transesterificación, recuperación del alcohol, separación del glicerol, lavado y purificación del biodiesel. La simulación del proceso de gasificación se realizó mediante un modelo estequiométrico teniendo en cuenta las reacciones fundamentales presentes en las etapas de pirólisis, combustión y reducción que ocurren en un gasificador en corriente descendente. Los productos obtenidos de la transesterificación mostraron altos rendimientos: 11% de glicerol y 98% de biodiesel. La composición del gas de síntesis de la gasificación se correspondió con las reportadas en la literatura. Se obtuvo un flujo volumétrico de gas de 92,38 m3/h con un poder calórico inferior de 5,67 MJ/Nm3, con un 72% de eficiencia del proceso. Debido a las limitaciones encontradas en la simulación del proceso de gasificación, se realizó una validación en Aspen Plus que mostró igualdad de resultados entre ambos simuladores.
