[2B13] [Invited] Renewable energy utilization systems toward carbon zero society considering regional specific conditions

○Kazuei Ishii¹ (1. Hokkaido University)

再生可能エネルギーの利用を拡大するためには、電気のみならず、加熱・冷熱、輸送エネルギーのすべてのエネルギーを考慮して、かつ地域特性に応じたエネルギー変換、貯蔵、輸送、利用までのサプライチェーンを構築する必要がある。本報告では、特にバイオマスエネルギーのシステム構築事例とその課題について講演する。

[2B15] Continuous conversion of glycerol to lactic acids over metal-acid bifunctional catalyst

○Erisa Kano¹, Takeshi Aihara¹, Hiroki Miura^1,2,3, Tetsuya Shishido^1,2,3 (1. Tokyo Metropolitan University, 2. Research Center for Hydrogen Energy-based Society, 3. Elements Strategy Initiative for Catalysts and Batteries Kyoto University)

In this study, we investigated the continuous synthesis of lactic acid (LA) from glycerol (Gly) in a flow reactor. Various supported Pt catalysts were investigated, and LA was formed when a support with an acid point was used. In particular, when layered niobium oxide (L-Nb₂O₅) was used as a support, oxidation by Pt and acid catalyzed reaction by L-Nb₂O₅ proceeded efficiently, stable Gly conversion was obtained without the addition of base, and LA was obtained continuously with high LA selectivity (>70 %) for a long time.
