石炭採掘時に排出される低濃度メタンガスを大気放出せず、ソーレ効果を利用して分離・濃縮する手法を提案。従来技術の欠点を踏まえ、理論解析と実験により初期メタン濃度と分離性能の関係を検証し、エネルギー回収と温室効果ガス削減の可能性を示す。
English
This study proposes using the Soret effect to separate and enrich methane from low-concentration coal mine gas, which is typically vented, causing energy waste and greenhouse gas emissions. Through theoretical analysis and experiments, it examines the impact of initial methane concentration on separation performance, offering a potential approach for energy recovery and emission reduction.

📄 Abstract（原文）
During coal mining operations, substantial volumes of gas containing low-concentration methane are directly discharged into the atmosphere, leading to significant energy waste and intensification of the greenhouse effect. This paper proposes the utilization of the Soret effect for separating mixed gases and enriching methane from coal mine gas, targeting the deficiencies inherent in conventional gas enrichment technologies. Through theoretical analysis, the initial methane concentration and t...
