“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 technology for the complete electro-catalytic decomposition of hydrogen sulfide into hydrogen and sulfur has been recognized as internationally leading and is recommended for scale-up and application [1]. - The research team has successfully built a pilot demonstration facility in Xinxiang, capable of processing 100,000 cubic meters of hydrogen sulfide annually, achieving over 1,000 hours of stable operation [1][2]. - The technology has led to the production of sulfur with a purity greater than 99.95% and high-purity hydrogen gas exceeding 99.999% [1]. Group 2: Environmental Impact - Hydrogen sulfide, a common byproduct in natural gas extraction, oil refining, and coal chemical processes, poses significant health risks and environmental pollution, including acid rain formation [1]. - Utilizing renewable energy sources to drive this technology can effectively eliminate pollution while recovering substantial amounts of "green hydrogen," contributing to a clean and low-carbon energy system in China [3]. Group 3: Industrial Application - The technology provides a new pathway for the complete elimination and resource utilization of hydrogen sulfide, offering dual resource recovery of hydrogen and sulfur, which can enhance the production of clean low-carbon hydrogen in various industrial sectors [3]. - Future applications of this technology are expected to be promising in coal chemical, petrochemical, and oil and gas extraction industries [3].
