Biomass Project Research Center, Hiroshima University, and HOSTY Association are co-organizing the Hiroshima University Biomass Evening Seminar. This seminar covers topics from the fundamentals of biomass to the latest information so that it can contribute the activities on biomass in this district. The 95th seminar will be held as follows. Please join.
Please wear a mask to protect against corona when participating.
You can also join on-line. If you want to join on-line, please send mail to bprc@hiroshima-u.ac.jp to let us know. Only ZOOM is used. Please understand that materials cannot be distributed and that there are possibilities of not being able to accept questions or bad connection.

“Effect of addition timing of radical scavengers in supercritical water gasification”

Supercritical water gasification (SCWG) is expected to be the next generation technology to generate energy from biomass. However, Char, a solid product formed by side reactions, can clog the reactor during long-term operation, cling to and deactivate the catalyst, and even reduce the carbon gasification yield. Recent studies have shown that the addition of acetic acid and formic acid as radical scavengers can inhibit the formation of char in SCWG of guaiacol. In this study, SCWG was carried out using guaiacol as a raw material, and radical scavengers were added during the heating of the raw material. The effect of the addition timing of radical scavengers and varying the concentration of radical scavengers on the product were evaluated.

“Preparation of sustainable macromolecular materials from unused plant biomass by chemical modifications”

Sustainable macromolecular materials with hydrophilicity or heat resistance were derived from plant biomass such as weeds along the roadsides or lignin polymers in unutilized wood through several chemical processes. Several properties of plants such as strength or flexibility are produced by plant cell walls, which are composed of complicated semi-IPN composites with cellulose, hemicellulose and lignin. Investigation on characterization and properties of these macromolecular composites were carried out.
