“…During the pyrolysis of thermoplastic materials (i.e., polystyrene, polyethylene), melting of the polymer occurs first, leading to a well-mixed bulk material inside the reactor as reported by Undri et al [81,82]. A similar effect could be emulated performing co-pyrolysis under MWs of oil-based cuts mixed with oil sands and biomass [83,84], or with sewage sludge [85]. In these cases, the increased temperature homogeneity could be ascribed to the presence of high boiling point liquids that promote homogenous heat transfer inside the reacting mixture.…”

Microwave-assisted pyrolysis is a promising thermochemical technique to convert waste polymers and biomass into raw chemicals and fuels. However, this process involves several issues related to the interactions between materials and microwaves. Consequently, the control of temperature during microwave-assisted pyrolysis is a hard task both for measurement and uniformity during the overall pyrolytic run. In this review, we introduce some of the main theoretical aspects of the microwaves–materials interactions alongside the issues related to microwave pyrolytic processability of materials.

“… 32 In other words, it is the pseudo-catalytic effect of microwave heating. 33,34 It is worthwhile noting that the tar conversion efficiency reached up to 97.3% at 700 °C and was only slightly increased as the temperature increasing to 800 °C, for the Ni/RHC-4 catalyst under microwave condition. The tar conversion efficiency at 700 °C under microwave condition was even higher than that at 800 °C under conventional condition, also indicating that microwave heating was more effective on heterogeneous catalytic reactions.…”

In the present work, biomass pyrolysis tar cracking and reforming for high quality syngas production using a rice husk char (RHC)-supported nickel catalyst (Ni/RHC) coupled with microwave heating was investigated. The Ni/RHC catalyst exhibited a high catalytic performance on tar removal and contributed well to the production of CO and H 2 . The conversion efficiency could reach up to 97.3%, and the CO and H 2 yields were 274.0 ml g À1 and 248.9 ml g À1 , respectively, at 700 C, under microwave conditions, when the nickel loading amount was 10.42 wt% of the support. The tar conversion efficiencies and syngas yields significantly increased as the cracking temperatures increased from 500 C to 700 C and the nickel loading amount increased from 0 to 10.42 wt%. The Ni/RHC catalysts became more effective for tar removal and the production of syngas increased under microwave conditions compared to the results obtained under conventional conditions.

“…Compared with traditional heating methods, microwave heating has the advantages of easy operation, uniform heating of materials, and rapid temperature rise, and the treatment time of microwave heating can usually be reduced to 1% of the time required to use in the electric heating method. Due to its fast heating speed, it may increase production speed, reduce power consumption, and reduce production costs (Hou et al, 2018;Putra et al, 2022). In addition, the aromatic hydrocarbons in the pyrolysis product produced by microwaveassisted catalytic pyrolysis of biomass are greater than those produced via traditional heating methods.…”

In this work, Camellia oleifera Abel shell was used as a feedstock to prepare biochar by HNO3 impregnation and pyrolysis. The biochar was used for the catalytic pyrolysis of waste vegetable oil to prepare bio-oil. Experimental results showed that HNO3 solution treatment had an important effect on the groups and structure of the biochar catalyst. When the solid/liquid ratio of pretreatment was 1:3, the Brunauer–Emmett–Teller specific surface area of the 1:3–600°C biochar is 392.65 m2/g, which is approximately 677 times higher than that of untreated biochar. Moreover, the biochar catalyst had a remarkable catalytic performance. The selectivity of the monocyclic aromatic hydrocarbon in the bio-oil was up to 78.82%, and the oxy-compound could be completely removed at the catalytic temperature of 600°C. However, the increase of the catalyst-to-waste vegetable oil ratio and catalytic temperature decreased the bio-oil yield.
