Biochar properties vary, and characterization of biochars is necessary for assessing their potential to sequester carbon and improve soil functions. This study aimed at assessing key surface properties of agronomic relevance for products from slow pyrolysis at 250-800 °C, hydrothermal carbonization (HTC), and flash carbonization. The study further aimed at relating surface properties to current...
In this paper the polychlorinated-dibenzo dioxins and furans (PCDD/Fs) release is analyzed during an hydrothermal carbonization process of the organic fraction of municipal solid waste (OFMSW). Two models to estimate the quantity of PCDD/Fs that can be released during this kind of process are presented in this paper. The first model follows a mass balance approach; the second one develops a phe...
The novel carbon based acid has been synthesized via one-step hydrothermal carbonization of furaldehyde and hydroxyethylsulfonic acid. A highly efficient procedure for the synthesis of fructone has been developed using the novel carbon based acid. The results showed that the catalyst possessed high activity for the reaction, giving a yield of over 95%. The advantages of high activity, stability...
