People.cn (SH:603000) Ren Min Wang·2026-01-08 01:55Core Viewpoint - The development of a new technology for the efficient and clean treatment of hydrogen sulfide (H2S) has been achieved by a team led by Academician Li Can from the Dalian Institute of Chemical Physics, which is recognized as a leading international solution in the energy and chemical industry [1][2]. Group 1: Technology Development - The "off-site electro-catalytic complete decomposition of hydrogen sulfide to produce hydrogen and sulfur technology" has been successfully developed, addressing the challenge of scaling up the decomposition of H2S [2][3]. - This technology decouples chemical reactions and charge transfer, allowing for the oxidation of H2S to sulfur and proton reduction to hydrogen to occur separately in a reactor, enhancing safety and reliability [2][3]. Group 2: Industrial Application - The team has initiated the first industrial demonstration project in the coal chemical sector, utilizing H2S as a byproduct from a methanol production facility [3]. - The demonstration plant has a capacity of 100,000 cubic meters per year and has achieved complete conversion of H2S, with sulfur purity exceeding 99.95% and hydrogen purity exceeding 99.999% [3]. Group 3: Environmental and Economic Impact - The technology offers a new pathway for the complete elimination and resource utilization of H2S, contributing to ecological protection and dual resource recovery of hydrogen and sulfur [4]. - If implemented using renewable energy sources, the technology could recover approximately 730,000 tons of clean low-carbon hydrogen annually from the 8 billion cubic meters of H2S processed in China, representing 40% of the planned green hydrogen production capacity by 2030 [4].
