Experimental data on the production and characterization of biochars derived from coconut-shell wastes obtained from the Colombian Pacific Coast at low temperature pyrolysis

Abstract

Biochars are emerging eco-friendly products showing outstanding properties in areas such as carbon sequestration, soil amendment, bioremediation, biocomposites, and bioenergy. These interesting materials can be synthesized from a wide variety of waste-derived sources, including lignocellulosic biomass wastes, manure and sewage sludge. In this work, abundant data on biochars produced from coconut-shell wastes obtained from the Colombian Pacific Coast are presented. Biochar synthesis was performed varying the temperature (in the range: 280 °C–420 °C) and O2 feeding (in the range: 0–5% v/v) in the pyrolysis reaction. Production yields and some biochar properties such as particle size, Zeta Potential, elemental content (C, N, Al, B, Ca, Cu, Fe, K, Li, Mg, Mn, Na, P, S, Ti, Zn), BET surface area, FT-IR spectrum, XRD spectrum, and SEM morphology are presented. This data set is a comprehensive resource to gain a further understanding of biochars, and is a valuable tool for addressing the strategic exploitation of the multiple benefits they have.

Supercritical Water Gasification of Coconut Shell Impregnated with a Nickel Nanocatalyst: Box–Behnken Design and Process Evaluation

“…Energy can be obtained from coconut shells through thermochemical methods such as pyrolysis and gasification. Several authors have researched the pyrolysis of coconut shells, focusing on producing liquid and solid products [2][3][4]. Coconut shells have also been used as a feedstock for conventional gasification processes, aiming to produce synthesis gas [5][6][7][8].…”

Feasibility study of coconut shell biochar production using community-scale biochar kiln

“…However, the BET surface area of biochar obtained in this work was still in the same range as those of previous studies. According to the results of Castilla-Caballero et al [37], the BET surface area values of biochar derived from coconut shells obtained from the Colombian Pacific Coast were in the range of 9.85 m²•g -1 to 15.75 m²•g -1 after varying pyrolysis temperature and oxygen-feeding content in the pyrolysis reaction. Babatabar et al [35] found that after pyrolyzing lignocellulosic and algal biomasses in a fixed-bed reactor, the BET surface area of coconut shell-derived biochar was 26.22 m²•g -1 .…”
