Core Viewpoint - The innovative technology developed by the team led by Academician Li Can enables the direct conversion of 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 electrochemical decomposition of hydrogen sulfide into hydrogen and sulfur has been developed with independent intellectual property rights in China [2]. - The design of the technology allows the chemical reactions to occur in a separate reactor, avoiding issues such as solid sulfur clogging and contamination of electrodes, thus enabling stable and efficient large-scale operations [2]. - The research team has applied for 26 patents related to this technology, with 12 already granted, forming a comprehensive patent portfolio [2]. Group 2: Industrial Application - A pilot demonstration facility capable of processing 100,000 cubic meters of hydrogen sulfide annually has been successfully established in Xinxiang, Henan, which has operated stably for over 1,000 hours [1]. - The facility has achieved complete conversion of hydrogen sulfide, producing sulfur with a purity greater than 99.95% and high-purity hydrogen gas exceeding 99.999% [1]. - The technology is expected to have promising applications in coal chemical, petrochemical, and oil and gas extraction industries, contributing to the green transformation of these sectors [3]. Group 3: Environmental Impact - Utilizing renewable energy sources to drive this technology can significantly reduce pollution while recovering substantial amounts of "green hydrogen," which is crucial for building a clean and low-carbon energy system in China [3]. - The technology provides a new pathway for the complete elimination and resource utilization of hydrogen sulfide, effectively protecting the ecological environment and achieving dual resource recovery of hydrogen and sulfur [3].
