The potential of biochar derived from banana peel/Fe3O4/ZIF-67@K2CO3 as magnetic nanocatalyst for biodiesel production from waste cooking oils

Results in Engineering, Journal Year: 2024, Volume and Issue: 22, P. 102005 - 102005

Published: March 16, 2024

Using biomass-based catalysts in biodiesel production can make the process more economical and environmentally friendly. In this study, a new magnetic nanocatalyst was developed using banana peel biochar, ZIF-67, Fe3O4, K2CO3, then utilized catalytic transesterification to convert waste cooking oils (WCO) into biodiesel. The level of free fatty acids treated WCO (WCOT) reduced generate with suitable characteristics. physicochemical aspects were characterized by Fourier-transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) map techniques. process, effect temperature, methanol-to-oil ratio, time, weight on potential produce from WCOT explored. highest yield (96.82%) (99.18%) attained at 65 °C, 3 wt %, ratio 19:1, processing time h, mixing rate 600 rpm. Based thermodynamic studies, endothermic non-spontaneous. regeneration studied various solvents n-hexane had good ability recover catalyst (90% up 5 stages). results 1H NMR test revealed that desired high WCOT. properties produced met ASTM D6751 EN 14214 standards.

Edible waste oil to biofuel using reclaimable g-C3N4/HAp/Fe3O4/K2CO3 nanobiocomposite catalyst: Toxicity evaluation and optimization

Environmental Technology & Innovation, Journal Year: 2023, Volume and Issue: 32, P. 103403 - 103403

Published: Oct. 12, 2023

In the current work, new heterogeneous nonobiocomposite of g-C3N4/HAp/Fe3O4/K2CO3 was made from chicken bone and melamine used in biofuel generation edible waste oil (EWO). FTIR, SEM, Map-EDX, BET, VSM, XRD techniques confirmed that catalyst synthesized. The magnetic saturation number BET value were determined to be 8.89 emu.g-1 3.95 m2.g-1, respectively. impact temperature, time, mass, ratio methanol: Oil (MeOH: Oil) on production explored using response surface method-central composite design. maximum yield EWO (98.52%) achieved at contact time 150 min, temperature 65 oC, amount 3 wt%, MeOH: 15:1. Activation energy k0 for transesterification process computed 58.91 kJ.mol-1 3.24×107 min-1, values ΔH ΔG positive process, which indicates is exothermic non-spontaneous. environmental factor (E) also showed has negligible harmful effects environment. can effectively reused many times process. produced good compliance with famous standards serve as a suitable fuel source.
