“…Processes such as calcination (Gu et al 2018), hydrodistillation (Tavares et al 2020), lyophilization (Rubio et al 2020), anaerobic anaerobic digestion (Alrefai et al 2020), extraction (Akond and Lynam 2020), fermentation ( Coimbra et al 2021), enzymatic hydrolysis (Corchado-Lopo et al 2021), hydrothermal liquefaction (Cervi et al 2021), saccharification (Marques and Aguiar-Oliveira 2020), transesterification (Khounani et al 2021b) among others, they are difficult to implement due to the great procedural and technological complexity, which requires greater investment, especially in equipment and infrastructure, making it difficult to implement as a strategy for the use of waste in the Extreme South of Bahia. The simplest processes that facilitate implementation in the region are found in other bioproducts, such as soil corrective using orange peel and sugarcane bagasse (Debernardi-Vázquez et al 2020) for composting, biochar using pie castor bean (Silva et al 2021), sunflower seed (Casoni et al 2019), cherry kernel (Pollard and Goldfarb 2021), filter cake and sugarcane molasses (Bernardino et al 2018;, branches, stems, roots and leaves of trees (Martín et al 2017), oat husk (Srivastava et al 2020), baru endocarp/mesocarp (Rambo et al 2020a;Rambo et al 2020b), coffee and cocoa husks (Milian-Luprón et al 2020) obtained by pyrolysis and briquettes using tree branches, trunks, roots and leaves (Nunes et al 2019;Ponte et al 2019), husk from coconut (Nunes et al 2019) and sugarcane bagasse (Ponte et al 2019) through crushing and compaction.…”

The expansion of agricultural production is increasingly accelerated, as a result of the greater need for food caused by population growth and, consequently, this growth results in the generation of greater amounts of waste. In general, the inspection of public environmental agencies and society demand from agribusinesses actions that increasingly seek the use of new environmental technologies for the destination of production residues, which can drastically reduce the impacts caused to the environment, in addition to add

“…The outlet gas was sampled by a mass spectrometer (Extorr XT Series RGA XT300M) through a fused silica capillary (internal diameter: 40 μm) to measure the toluene concentration at the dominant mass to charge ratio of 91. Proximate analysis to determine the fixed carbon, volatile matter, and inorganic content was performed on a TA Instruments TGA 5500 as described previously 31 . Surface area and porosities were measured via N 2 physisorption at 77 K over a P / P 0 range of 0 to 0.7 on a Micromeritics 3‐Flex using the Brunauer–Emmett–Teller (BET) and t‐plot methods after being degassed for 24 h at 250°C on a Micromeritics Smart VacPrep.…”

Capturing the effects of particle heterogeneity on adsorption in a fixed bed

To efficiently design new adsorption systems, industrial scale fixed beds are often scaled down to bench‐top experiments and/or modeled using computational fluid dynamics (CFD). While there has been considerable work exploring adsorption of volatile organics onto activated carbon fixed beds in the literature, this article attempts to reckon with the high variability of adsorption capacities observed at small scales and improve small‐scale experiments for industrial scale reactor design. This study integrates experimental results with CFD simulations, which can explicitly model system heterogeneities and their influence on adsorption by resolving local packing densities and flow paths. Activated carbon physical properties were determined through surface area analysis, proximate analysis, and toluene adsorption (measured via mass spectroscopy). Variability in the small‐scale systems was not attributed to surface area or carbon content, as is often stated, but instead was due to local packing density variations and the heterogeneity of particle size distributions.

“…Additionally, significant quantities of cherry pits also come from other areas of the food and distillery industries. In recent years, there have been several studies on the recovery of sour cherry pits [18][19][20]. The oils obtained from cherry pits are recommended for use in cosmetics and cooking due to the presence of fatty acids [19].…”

Physicochemical Characterization of Cherry Pits-Derived Biochar

Although the suitability of some biochars for contaminants’ sorption separation has been established, not all potential feedstocks have been explored and characterized. Here, we physicochemically characterized cherry pit biochar (CPB) pyrolyzed from cherry pit biomass (CP) at 500 °C, and we assessed their As and Hg sorption efficiencies in aqueous solutions in comparison to activated carbon (AC). The basic physicochemical and material characterization of the studied adsorbents was carried out using pH, electrical conductivity (EC), cation exchange capacity (CEC), concentration of surface functional groups (Boehm titration), and surface area (SA) analysis; elemental C, H, N analysis; and Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM–EDX). AsO43− anions and Hg2+ cations were selected as model contaminants used to test the sorption properties of the sorption materials. Characterization analyses confirmed a ninefold increase in SA in the case of CPB. The total C concentration increased by 26%, while decreases in the total H and N concentrations were observed. The values of carbonate and ash contents decreased by about half due to pyrolysis processes. The concentrations of surface functional groups of the analyzed biochar obtained by Boehm titration confirmed a decrease in carboxyl and lactone groups, while an increase in phenolic functional groups was observed. Changes in the morphology and surface functionality of the pyrolyzed material were confirmed by SEM–EDX and FTIR analyses. In sorption experiments, we found that the CPB showed better results in the sorption separation of Hg2+ than in the sorption separation of AsO43−. The sorption efficiency for the model cation increased in the order CP < CPB < AC and, for the model anion, it increased in the order CPB < CP < AC.
