“…Acid hydrolysis of cupuaçu husks produced a satisfactory flavoring in the production of vanilla, bacon, ham, whiskey, and rums and currently recognized for its anti-inflammatory potential (Zhao et al, 2019). Brito et al (2020) verified the predominant presence of vaccenic acid (21.2%), palmitic acid (19.7%), and furfural (7%) compounds in bio-oil derived from pequi residual biomass. Rambo et al (2021), like this study, identified guaiacol (28.7%) and creosol (22.5%) compounds in bio-oil derived from baru hydrolyzed endocarp.…”

Lignocellulosic waste is a valuable source of energy, fuels, and raw materials for the chemical industry. In this study, the potential of cupuaçu husks, derivative from a typical fruit of the Brazilian Amazon, was evaluated. Therefore, biomass was submitted to acid hydrolysis and pyrolysis, and the contents of sugars, by-products, bio-oil compounds, and bio-oil theoretical energy potential were determined. X-ray diffraction, High performance liquid chromatography, Fourier-transform infrared and Gas chromatography mass spectrometry analyzes were used. The hydrolysate has considerable sugar levels (31.7%) and presence of relevant by-products including furfural, levulinic acid and hydroxymethylfurfural. Bio-oil contained a variety of phenolic compounds, and its theoretical energy potential suggested usability of cupuaçu husks for energy generation. Economic analysis showed that commercialization of bioproducts obtained by biomass hydrolysis and pyrolysis could be highly profitable. These outcomes indicate a range of applications for cupuaçu husks in biorefinery processes and potential to promote sustainability and social development.

The biochar of the Pequi peel represents a sustainable alternative in the process of treating effluents through adsorption system. This study investigates the adsorption capacity in a fixed bed column of the activated biochar from pequi peel (ABPP) to remove the components. The biochar was obtained by pyrolysis, which was activated with zinc Chloride - ZnCl₂. Through the Thomas model, it was found that the concentration of Paracetamol of 5 mg L-1 obtained 3.21 mg g-1 of drug adsorption, which was higher than the adsorption obtained with the concentrations of 10 mg L-1 (3.02 mg g-1) and 20 mg L1 (1.22 mg g-1). Methylene blue was tested with a concentration of 3 mg L-1, adsorbing 8.07 mg g-1. The data fit the Thomas model with an R² higher than 0.90. The capacity of ABPP to adsorb methylene blue and Paracetamol was satisfactory, with adsorbing significant.

Lignocellulosic biomass residues can generate interesting materials for the chemical and food industries. Physical activation processes were developed by cold pressing and slow pyrolysis, as well as physical chemical activation with zinc chloride (ZnCl 2 ), to produce bio-based products, including bio-oil (30%) and biochar (31%), with good yields. Charcoal and biooil provided good results, respectively, with regard to adsorption capacity (357 m 2 g -1 of surface area BET) and the possibility of extracting chemical compounds (phenols with 45.81% and aldehydes with 32.76%). Moreover, the key economic performance indicators of the process were analyzed, and the results indicate that the proposed process is economically feasible and attractive with $422,416.10 profits. Finally, after dialoguing with the babassu nut breakers and understanding their needs, the feasibility of economically developing the contacted families through technology transfer for extracting the oil, cake, biochar, and bio-oil from babassu coconuts was studied, demonstrating the possibility of income generation based on the profitability achieved in this study.
