  • Electrolyzer Technologies in Toluene Direct Electro-hydrogenation for Methylcyclohexane Synthesis

    NAGASAWA Kensaku, MITSUSHIMA Shigenori

    Journal of the Japan Petroleum Institute   67 ( 3 )   97 - 104   2024.5

    <p>This review presents an overview of the development of an electrolyzer for the direct electrohydrogenation of toluene, a one-step electrochemical process for directly synthesizing methylcyclohexane from toluene and water utilizing solid polymer electrolyte (SPE) membranes. Reducing the cell voltage and enhancing the current efficiency are important to improve the performance of a toluene direct electrohydrogenation electrolyzer. To improve these characteristics, the electrolyzer components consisting of the flow field, the diffusion layer, the anode mesh size, and the collector and cathode catalyst layer were modified and optimized. Investigation of the flow field structure found that the porous carbon flow field exhibited the highest performance, with remarkable improvement in current efficiency. Decrease in current efficiency indicates hydrogen gas generation at the cathode. However, loading of the Pt catalyst in the porous carbon flow field on the cathode side resulted in chemical reaction of the hydrogen gas generated in the catalyst layer with toluene utilizing the Pt catalyst, which significantly improved the overall current efficiency. Smaller mesh size of the anode and heat-pressing treatment of the anode current collector reduced the cell voltage with increased cathode catalyst utilization ratio by improvement of surface pressure uniformity and membrane flatness. The toluene permeation properties of various SPE membranes were determined and the relationship between the catalyst layer thickness and electrolysis performance was clarified. The developed technologies improved the cell voltage at 0.4 A cm<sup>−2</sup> current density from 2.10 to 1.72 V and achieved more than 90 % toluene conversion in continuous single-flow operation.</p><p>This review presents an overview of the development of an electrolyzer for the direct electrohydrogenation of toluene, a one-step electrochemical process for directly synthesizing methylcyclohexane from toluene and water utilizing solid polymer electrolyte (SPE) membranes.

    再エネはコストが低減して普及が進む一方で、発電と消費の時間や場所が一致しないことや需給が一致しないことが課題となっている。これらの課題を解決するために、再エネとトルエンから有機ハイドライド(メチルシクロヘキサン(MCH))を合成する有機ハイドライド電解合成法が開発された。この技術は、MCHを安価に合成することのできる画期的な技術であったが、本発明出願当時は製造効率が短期間で低下するという耐久性の問題があった。  本発明では、まずこの製造効率低下の原因の一つが、イオン交換膜を透過したトルエンやその反応物質であることを特定した。さらに、適切な位置にガスを導入して速やかにトルエンを除去することにより、電解槽の経時的な製造効率の低下を大幅に抑制することに成功した。本発明により、実証スケールへ移行することができ、2023年には豪州でのパイロットプラントの建設、運転や日豪間のグリーン水素サプライチェーン実証にも成功した。
