Towards biowastes valorization: Peanut shell as resource for quality chemicals and activated biochar production

Abstract The purpose of this work was to transform a regional biowaste into value-added chemicals and products through modest thermo-catalytic pyrolysis process. ZSM-11 (Zeolite Socony Mobile-11) zeolites modified by nickel (Ni) incorporation (1–8 wt%) were synthesized characterized means X-Ray Diffraction, Inductively Coupled Plasma Atomic Emission Spectroscopy, Infrared Fourier Transform UV–Vis Diffuse Reflectance Spectra Temperature Programmed Reduction. Results demonstrated that Ni mainly incorporated as oxide. These porous materials evaluated heterogeneous catalysts improve biooil composition. In sense, higher hydrocarbon yields, quality obtained oxygenates diminished. deactivation the most active material studied over six cycles reaction. order achieve circular bioeconomy postulates, biochar (usually considered residue) further transformed physicochemical activation. activated biochars extensively characterized.
