Preparation of valuable pyrolysis products from poplar waste under different temperatures by pyrolysis: Evaluation of pyrolysis products

Effect of Reaction Conditions on Energy Yield of Pyrolysis Gas from Apple Tree Branches

“…This pattern can be explained by the pyrolysis gas generation process. At approximately 300 °C, depolymerization of holocellulose results in the formation of high oligomers, which are subsequently converted to levoglucosan and light volatiles . At 550 °C, lignin’s methyl-containing branched chains pyrolyze, resulting in a significant production of CH 4 .…”

Potential of agro-industrial residues from the Amazon region to produce activated carbon

“…The studied AC had a larger surface area than those reported in the literature, which enabled us to infer that the carbons produced are likely to have a high adsorption capacity. Some studies show that the surface area of charcoal tends to increase significantly at lower pyrolysis temperatures (between 400 and 600 °C) and tends to decrease at higher temperatures (between 700 and 800 °C) [ 56 ]. However, it is worth noting that in the present study, activating chemistry agents were used, which ended up contributing efficiently to increasing the surface area of the carbon, demonstrating the importance of activation at correct temperatures and with the good use of activating agents.…”

Response Surface Methodology—Central Composite Design Optimization Sugarcane Bagasse Activated Carbon under Varying Microwave-Assisted Pyrolysis Conditions

“…Microwave and conventional pyrolysis of biomass is usually carried out under inert gases such as N 2 to maintain an oxygen-free environment for pyrolysis to take place [24,25]. Even though previous studies have demonstrated the benefits of microwave pyrolysis for biomass utilization, the continuous use and consumption of N 2 have contributed to higher operating costs, limiting scale-up and industrial applications [26]. The vacuum pyrolysis environment of microwave vacuum pyrolysis (MVP) replaces the commonly used N 2 environment, reducing the use and consumption of N 2 , and the negative pressure conditions aid in accelerating the thermal cracking reaction and aid in the discharge of the pyrolysis volatiles, producing AC with higher yields and cleaner pores [27].…”
