Pyrolysis of antibiotic mycelial dreg and characterization of obtained gas, liquid and biochar

• Value-added products was recycled from antibiotic mycelial dreg (AMD). Antibiotic residue in AMD removed after pyrolysis. N mainly distributed biochar and liquid, while P retained biochar. Low pyrolysis temperature benefits the recycling of P. The disposal by fully conform to related principles. utilization (AMD), which has been identified as a hazardous waste China, are serious concern because residual huge annual output. Pyrolysis is promising technology treat AMD. However, not studied an adequate degree, particularly no attention paid release distribution phosphorus during Therefore, present work more comprehensively. influence on product yields characteristics, together with nitrogen phosphorus, products, were investigated. results suggested that eliminated Nitrogen contained liquid Liquid characterized abundant oxygen nitrogen-containing compounds, featured both inorganic phosphate groups. showed significant effect low recommended considering phosphorus. through conforms principles disposal.
