Microwave-assisted catalytic pyrolysis (MACP) of biomass into high-value products is a promising strategy for solving the global increasingly severe energy and environmental issues. However, this still limited by lack low-cost efficient catalysts with strong microwave absorption. In study, series biochar materials derived from spent lithium-ion batteries (BC, HC, sLFPHCs sNCMHCs) were developed in MACP biomass. Microwave absorption characteristics rice straw these investigated. The results showed that have better than SiC. Since increase graphitization after calcination, their ε' ,ε" tanδε increased RLmin decreased significantly together higher maximum heating rates (630 ~720 ℃/min) at power 800W (2.45GHz). yields H2-rich syngas lower liquid 360W less 350 ℃. Analysis increases hydrocarbon content, especially monocyclic aromatic hydrocarbons (MAHs), polymerization MAHs to form polycyclic was inhibited. particular, sNCMHC-C obtained highest selectivity H2 (50.22 vol. %) gaseous products, (18.86 area. benzene, 1-propynyl- (17.41 products. This study suggests has high potential promote recycling waste
