Further utilization of solid carbon accruing during the process (i.\u2009e., in battery industry or for metallurgy) increases the process's economic chances. This study demonstrated the feasibility of gas\u2010phase methane pyrolysis for hydrogen production and carbon capture in an electrically heated high\u2010temperature reactor operated between 1200 and 1600\u2009\u00b0C under industrially relevant conditions. While hydrogen addition controlled methane conversion and suppressed the formation of undesired byproducts, an increasing residence time decreased the amount of byproducts and benefited high hydrogen yields. A temperature of 1400\u2009\u00b0C ensured almost full methane conversion, moderate byproduct formation, and high hydrogen yield. A reaction flow analysis of the gas\u2010phase kinetics revealed acetylene, ethylene, and benzene as the main intermediate products and precursors of carbon formation.<\/jats:p>","DOI":"10.1002\/cssc.202201720","type":"journal-article","created":{"date-parts":[[2022,11,22]],"date-time":"2022-11-22T16:29:42Z","timestamp":1669134582000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Hydrogen Production and Carbon Capture by Gas\u2010Phase Methane Pyrolysis: A Feasibility Study"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8683-2155","authenticated-orcid":false,"given":"Patrick","family":"Lott","sequence":"first","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manas B.","family":"Mokashi","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heinz","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominik J.","family":"Heitlinger","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Lichtenberg","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akash B.","family":"Shirsath","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1404-893X","authenticated-orcid":false,"given":"Corina","family":"Janzer","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9272-5556","authenticated-orcid":false,"given":"Steffen","family":"Tischer","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1617-3112","authenticated-orcid":false,"given":"Lubow","family":"Maier","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9211-7529","authenticated-orcid":false,"given":"Olaf","family":"Deutschmann","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technology and Polymer Chemistry Karlsruhe Institute of Technology (KIT)  Engesserstr. 20 76131 Karlsruhe Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,12,8]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"crossref","unstructured":"IEA The Future of Hydrogen: Seizing today's opportunities Paris 2019.
