“Development of high-performance zeolite catalysts guided by the molecular design of organic structure-directing agents”（14：15-14：45, Oct. 30）

 Yoshihiro KUBOTA, Yokohama National Univ.

　A highly effective organic structure-directing agent (OSDA) was rationally designed and synthesized for the preparation of MSE-type zeolites. While conventional OSDAs required more than 10 days of crystallization, the newly developed OSDA enabled the formation of highly crystalline MSE-type zeolite within only 32 hours. The reduced crystallization time represents a significant improvement in synthesis efficiency. Catalysts derived from the resulting zeolites exhibited excellent catalytic performance, demonstrating the practical potential of this molecular design approach in zeolite catalyst development.

 

“Engineering porous materials for themocatalytic application” （14：45-15：15, Oct. 30）

 Sol AHN, Chung-Ang Univ.

　Heterogeneous catalysts play important roles in production of most of industrial products. Among them, supported catalysts are one class, and porous metal oxides materials are frequently used as supports for heterogeneous catalysts. In pursuit of efficient use of catalysts, how to design and synthesize catalysts are of the utmost importance. In this presentation, various strategies are introduced, mainly grafting of active sites on the surface, on various hydrocarbon conversion reactions.

 

“Integrated catalyst and reactor design for sustainable CO₂ and CH₄ utilization”（15：30-16：00, Oct. 30）

 Sunkyu KIM, Pukyong National Univ.

　The mitigation of greenhouse gases such as carbon dioxide (CO₂) and methane (CH₄) is critical for addressing environmental challenges, while their transformation into valuable fuels and chemicals presents a promising opportunity. Maximizing the efficiency of CO₂ and CH₄ conversions with minimal energy demands a synergistic approach that combines advanced catalyst development with innovative reactor engineering. This presentation explores integrated methodologies for CO₂ and CH₄ conversion, focusing on the design of structurally tailored catalysts, the tandem catalytic systems, and the coupling of reactors with chemical looping processes to enhance selectivity and overall reaction performance. The study highlights the importance of co-developing catalysts and reactor configurations as a unified system to achieve more effective and sustainable petrochemical processes.

 

“Optimized zeolite beta and open-batch reactor design for enhanced cracking and hydrocracking of polyolefin waste” （16：00-16：30, Oct. 30）

Jong Hun KANG, Seoul National Univ.

　This presentation discusses catalytic cracking and hydrocracking of polyolefin waste using laboratory-synthesized, optimized zeolite beta and Ru/zeolite beta catalysts in an open-batch reaction system. Emphasis is placed on identifying external surface acid sites of zeolite beta as critical to enhancing liquid product selectivity. Reactor configuration optimization further increased liquid selectivity, achieving up to 75 % yield within a moderate temperature range of 300-330 °C. These findings provide significant insights into catalyst design and reactor engineering, highlighting practical pathways for efficient chemical recycling of polyolefin waste into valuable liquid hydrocarbons.

 

“Design of catalysts for efficient CO₂ conversion” （10：15-10：45, Oct. 31）

Shoji IGUCHI, Kyoto Univ.

　For the efficient and highly selective conversion of CO₂, it is crucial to design catalysts with a focus on CO₂ adsorption on their surfaces. This presentation will highlight solid catalyst materials we have developed for the electrolytic CO₂ conversion and photocatalytic conversion of CO₂.

 

“Modeling heterogeneous catalysis by AI that integrates experimental and theoretical data” （13：00-13：30, Oct. 31）

 Ray MIYAZAKI, Hokkaido Univ.

　Theoretical and experimental data were integrated using AI to clarify the properties of materials that describe catalytic performance. The effect of additive metals on the support was analyzed in the target of CO₂ hydrogenation in a silica-supported cobalt catalyst. Combining experimental and theoretical data improves the performance of the AI model, suggesting that cobalt silicate at the catalytic interface is an important site for methanol production. We also searched for new high-performance catalysts and tested the accuracy of AI by synthesizing them.
