Unlocking green potential: Enhancing biomass valorization via thermal depolymerization with spent catalysts

Year: 2023

Type: article

Abstract: Biomass is globally recognized as an up-and-coming environmentally friendly carbon-based energy source, Suitable catalysts for managing thermal depolymerization of biomass present an alternative method for reducing overall energy usage while maintaining the yield.The spent catalyst could increase bio-organics production by up to 11%,31%,6%,and 21% in rice straw,brown solid,alkaline, and dealkaline lignin pyrolysis, respectively. The amount of biochar produced in the thermal depolymerization was reduced to 18%,27%,35%,and 32% in rice straw, brown solid, alkaline, and dealkaline pyrolysis, respectively, upon utilizing the spent catalyst. These findings indicate the potential of the spent catalyst for the biomass thermal depolymerization process.
