“…54 Their porous structure veried their applications in wastewater bioremediation, soil treatment, and as a catalyst for biomass conversion. [73][74][75] The powder X-ray diffraction (XRD) technique was utilized to determine the crystallinity of the biomass and dry biochar samples by taking into account the changes in the crystalline structure of cellulose by the interruption of the hydrogen bonding of cellulose chains occurring due to liquefaction. 76 Fig.…”

“…This result may be due to the filling of micropores with ash products. This interpretation is supported by their negative correlation; high ash content in AC resulted in low adsorption (Hassan et al 2021). It is proposed that the higher activation temperature limited the accessible pathways in the AC.…”

Granular activated carbon (GAC) and powdered activated carbon (PAC) are the two most common forms of activated carbon with varying particle size range. The goal of this study was to analyze the key factors (particle size and activation temperature) affecting the surface characteristics of GAC and PAC derived from palm kernel shell (PKS). The surface morphology suggested that the pore network in PKS-PAC is more developed than that in PKS-GAC owing to the presence of a micropore structure when prepared at lower activation temperatures. This study also demonstrated that activation performed on different PKS particle size range influenced the mesopore domain of the activated carbon produced. The PKS-GAC was found to have more mesopores than PKS-PAC, which made it more reliable for dye adsorption in water treatment. Overall, this study demonstrated that applying different particle size range of PKS during the activation process can have a significant influence on the surface characteristics, thus having a direct impact on the application of activated carbon. An accurate particle size range will ensure that the most cost-effective activated carbon is selected to achieve the desired performance objectives.

“…In this way, pyrolysis is one of the most used alternate ways for the use of agro-industrial waste, which consists of the thermal decomposition of biomass in the absence of oxygen, which generates bio-gas, bio-oil, and a solid carbon-rich residue (biochar) [1,2]. The biochar among the products generated is considered a multi-functional material in which it can be used for soil conditioner [3], adsorbent [4], support for enzyme immobilization [5], or as a precursor to activated carbon [6] and graphene oxide [7].…”

The present research aims to study the process of immobilization of lipase from Burkholderia cepacia by physical adsorption on graphene oxide derived (GO) from grape seed biochar. Additionally, the modified Hummers method was used to obtain the graphene oxide. Moreover, Fourier transform infrared spectroscopy, Raman spectrum, X-ray diffraction, and point of zero charge were used for the characterization of the GO. The influences of pH, temperature, enzyme/support concentration on the catalytic activity were evaluated for the immobilized biocatalyst. The best immobilization was found (543 ± 5 U/g of support) in the pH 4.0. Considering the biochemical properties, the optimal pH and temperature were 3.0 and 50 °C, respectively, for the immobilized biocatalyst. Reusability studies exhibited that the immobilized lipase well kept 60% of its original activity after 5 cycles of reuse. Overall, these results showed the high potential of graphene oxide obtained from biochar in immobilization lipase, especially the application of nanobiocatalysts on an industrial scale.
