The increasing demand for sustainable waste utilization has led to a growing interest in cocoa shell as a valuable biomass resource. This study investigates the pyrolysis of cocoa shell, both untreated and acid-washed, at temperatures of 300, 400, and 500 °C to extract valuable compounds. Utilizing nitrogen as the pyrolysis atmosphere, we aimed to optimize conditions for the production of bio-oil enriched in valuable compounds.
Advancements in photocatalysis have transformed synthetic organic chemistry, using light as a powerful tool to drive selective chemical transformations.
Kraft lignin is a major industrial by-product of the pulp and paper industry, currently used primarily as low-value fuel. There are economic and environmental incentives to utilize kraft lignin for materials applications, however, its compositional variability and chemical complexity remains a major barrier to commercial use. Colloidal lignin particles (CLPs) have emerged as a promising strategy for reducing the heterogeneity of technical lignins by generating spherical particles with narrow size distribution.
This study aimed to evaluate sugarcane bagasse as a precursor for the synthesis of magnetic carbonaceous material (MC) produced at 230 °C via hydrothermal carbonization, followed by an activation process with KOH (1:2 and 1:4; m:m) at 700 °C under a nitrogen atmosphere (MAC). The study assessed the structure, texture, and adsorption capacity of MC and MAC for the dye methylene blue (MB). FTIR analysis was performed to investigate the structural properties, while BET and BJH analyses were conducted to determine the specific surface area and pore volume.
The goal of this research was to develop advanced silica materials from rice husk ash. A renewable and abundant agro-industrial waste that causes problems of accumulation and final disposal in the environment. Using extraction and synthesis methods, nanometric silica was produced. This silica was then used as a support material for nickel-based catalysts applied in CO2 hydrogenation reactions.This silica was then used as a support material for the development of nickel-based catalysts applied in CO2 hydrogenation reactions.
