【科技日报】“毒气”变宝藏 硫化氢资源化利用再辟新径

Core Viewpoint - The innovative technology developed by the team led by Academician Li Can from the Dalian Institute of Chemical Physics can convert toxic hydrogen sulfide into clean energy and high-value chemical products, marking a significant advancement in addressing environmental pollution from industries such as natural gas and petrochemicals [1][2]. Group 1: Technology Development - The team has developed a proprietary technology for the complete electro-catalytic decomposition of hydrogen sulfide into hydrogen and sulfur, overcoming challenges related to scaling up the engineering process [2]. - This technology utilizes a unique electronic mediation method to conduct chemical reactions in a separate reactor, avoiding issues such as solid sulfur clogging and contamination of electrodes [2]. - The technology has led to the establishment of a pilot demonstration facility in Xinxiang, capable of processing 100,000 cubic meters of hydrogen sulfide annually, producing sulfur with a purity exceeding 99.95% and high-purity hydrogen gas over 99.999% [1][2]. Group 2: Environmental Impact and Applications - Utilizing renewable energy sources to power this technology can significantly reduce pollution while recovering substantial amounts of "green hydrogen," contributing to China's clean and low-carbon energy system and industrial green transformation [3]. - The technology offers a new pathway for the complete elimination and resource utilization of hydrogen sulfide, effectively protecting the ecological environment and providing dual resource recovery benefits through hydrogen and sulfur production [3]. - There is strong potential for this technology to be applied in coal chemical, petrochemical, and oil and gas extraction industries, enhancing the production of clean low-carbon hydrogen [3].
