Activated Carbon (AC) derived from low-priced biomass materials has been identified as the efficient and cost-effective candidate for low-temperature CO2 adsorption technique performed, though suffering limited capture capacity heterogeneous fluidization in fluidized-bed systems have remained main challenges industrialization of carbonaceous sorbents. Herein, first time, novel, low-cost, highly fluidizable sorbent waste-based oleaster seed (OS) developed through mixing with coarse fluid catalytic cracking (FCC) particles. Hydrophobic SiO2 nanoparticles (NPs) which are well-known assistant enhanced hard-to-fluidize particles was also tested comparison. To determine best activator activator/precursor weight ratio, AC obtained pyrolysis OS prepared two disparate activators KOH ZnCl2, ratios 2, 3, 4, outcomes reveal highest average 2.78 mmol/g over three successive cycles KOH-activated ratio 2/1. This great OS-derived mixed different wt.% FCC NPs to boost its fluidity; which, bed expansion reached 1.6 3.5, at gas velocity 5 cm/s by 2.5 FCC, similar NPs-assisted sample. In addition homogeneous fluidizability, a superior multicyclic stability 95.5% during 25 multiple adsorption/desorption assessed. The FCC-mixed activated carbon both fluidity activity is introduced candidate.

Due to the CO2 emissions and greenhouse effect, reducing its harmful impacts on climatic conditions is necessary. adsorption in a microporous carbon structure one of more effective separation techniques avoid this type emissions. In work, biochar (BC) five activated carbons (ACs) were produced from Pinus radiata sawdust by chemical activation with potassium hydroxide (KOH) or zinc chloride (ZnCl2). Characterization was performed scanning transmission electron microscopy (SEM TEM), surface area pore size distribution volumetric N2 experiments using Brunauer-Emmet-Teller (BET) Barret-Joyner-Halenda (BJH) methods, respectively, X-ray diffraction (XRD), elemental analysis photoelectron spectroscopy (XPS). The performance efficiency analyzed terms capacity at an absolute pressure range 0-760 mmHg different temperatures (0, 25 50ºC). apparent IAST selectivity over determined all showed preferential sorption for CO2. Langmuir, Freundlich Toth isotherms employed analyze pure data isotherm gave best fit. 600ºC KOH ratio 1:4 w/w achieved largest uptake (5.79 mmol/g 0°C 750 mmHg) due combination between high microporosity (89%) (2437 m2/g). This also reached relatively selectivity.
