【新华社】化“毒”为“宝” 新技术助力破解硫化氢污染难题

Core Viewpoint - The research team led by Academician Li Can from the Dalian Institute of Chemical Physics has successfully developed a technology for the complete decomposition of hydrogen sulfide (H2S) into hydrogen and sulfur, addressing a significant environmental challenge posed by H2S emissions in the energy sector [1][2]. Group 1: Technology Development - The newly developed technology utilizes a novel electro-catalytic method to decompose hydrogen sulfide, which has been a long-standing challenge in industries such as natural gas extraction and petrochemicals [2]. - The technology has achieved a decoupling of chemical reactions and charge transfer in the reaction space, allowing for the oxidation of H2S to sulfur and the reduction of protons to hydrogen to occur separately outside the electrode [2]. - This innovation has led to the filing of 26 patents, with 12 already granted, ensuring complete independent intellectual property rights for the technology [2]. Group 2: Environmental Impact - The global annual processing volume of hydrogen sulfide exceeds 70 billion cubic meters, with China alone handling approximately 8 billion cubic meters each year, highlighting the scale of the environmental challenge [2]. - The new technology provides a pathway for the complete elimination and resource utilization of hydrogen sulfide, contributing to cleaner and low-carbon hydrogen production in industrial sectors [2]. - The advancement is significant for industries aiming to achieve carbon neutrality goals, aligning with broader environmental sustainability efforts [2].
