Kaur, Kumar, et al (2024) Py-GC/MS and slow pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More of tamarind seed husk. *Journal of Material Cycles and Waste Management.* https://doi.org/10.1007/s10163-024-01888-9

In the pursuit of sustainable energy sources, researchers have delved into the slow pyrolysis behavior of tamarind seed husk biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More. This study marks the first detailed exploration of slow pyrolysis, focusing on the characterization of pyrolysis products and breaking pathways using Py-GC/MS.

The experiments, carried out in a lab-scale glass tubular reactor at temperatures ranging from 300 to 450℃, unveiled promising results. The optimized conditions yielded a maximum bio-oil output of 38.8 wt.% at 400℃, with a conversion rate of 67.1 wt.%. Simultaneously, the biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More yield reached 32.9 wt.% during slow pyrolysis.

Various characterization techniques, including GC–MS, FTIR, 1 HNMR, XRD, SEM, and proximate analysis, were employed to analyze the slow pyrolysis bio-oil and biochar. GC–MS revealed the phenolic-rich nature of the bio-oil, showcasing its potential for diverse functionalities.

However, the study went beyond conventional analysis by employing flash pyrolysis through Py-GC/MS. This analytical tool provided a more profound understanding of the decomposition pattern, elucidating the breaking patterns within the biomass framework and outlining the mechanism.

In conclusion, this research not only highlights the untapped potential of tamarind seed husk biomass for biofuel production but also emphasizes the importance of advanced analytical tools in unraveling the complexities of pyrolysis processes.
