WebDec 14, 2024 · 3.2 Biochar catalyst production from pyrolysis of SSR. Thermally induced transesterification signified the conversion of SSE into biodiesel, whereas conventional acid-catalyzed (trans)esterification did not work for low-purity SSE. Nevertheless, the technical challenge in this process was the use of a higher reaction temperature (380 °C) to ... WebJan 15, 2024 · The effect of chemical speciation (H2O/NH4Ac/HCl-soluble and insoluble) of alkali and alkaline earth metallic species on the steam gasification of sawdust biochar was investigated in a lab-scale, fixed-bed reactor, with the method of chemical fractionation analysis. The changes in biochar structures and the evolution of biochar reactivity are … WebFeb 28, 2024 · The pyrolysis process produces a carbon-rich catalyst, and the residue is known as biochar. This biochar works well as a biocatalyst in the production of biodiesel.
