In order to substantially reduce CO<sub>2<\/sub>\u00a0emissions, it is important not only to control CO<sub>2<\/sub>\u00a0emissions through existing processes, but also to develop innovative processes to utilize CO<sub>2<\/sub>\u00a0as a resource for production of fuels and chemicals. The core of these efforts is technology to produce syngas, a carbon monoxide and hydrogen gas mixture, from CO<sub>2<\/sub>.<\/strong><\/p>\n\n\n\n<p>Syngas is produced by using a reverse water gas shift reaction (CO<sub>2<\/sub>+H<sub>2<\/sub>\u2192CO+H<sub>2<\/sub>O) that reduces CO<sub>2<\/sub>\u00a0to carbon monoxide by reaction with hydrogen. A highly active transition metal such as platinum, rhodium, nickel, or copper has been considered necessary as a catalyst component to facilitate this reaction. Prior to the reaction operation, the energy- and cost- intensive processes were necessary to separate and recover CO<sub>2<\/sub>\u00a0by a chemical absorption technique and subsequently purify it close to 100%. An innovative technology, which can directly produce syngas from low-concentration CO<sub>2<\/sub>\u00a0without these processes, needs to be developed. Recently, dual-function materials have been attracting attention to enable integrated CO<sub>2<\/sub>\u00a0capture and conversion<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Summary<\/h3>\n\n\n\n<p>In collaboration with Delft University of Technology, researchers in AIST developed a technology for directly producing syngas that is a highly versatile raw material for fuels and chemicals. This technology can utilize CO<sub>2<\/sub>\u00a0in exhaust gases from power plants and industrial sectors (~20%) as well as the low-concentration atmospheric CO<sub>2<\/sub>\u00a0(400 ppm; 0.04 %) to produce syngas.<\/p>\n\n\n\n<p>This technology can directly produce syngas, a carbon monoxide and hydrogen gas mixture, by using the dual-function materials to react low-concentration CO<sub>2<\/sub>\u00a0with hydrogen derived from renewable energy, without separation and purification processes. While the conventional reaction to reduce CO<sub>2<\/sub>\u00a0to carbon monoxide required a catalyst using a transition metal, this technology employs the transition-metal-free dual-function material which has a simple composition with an alkali or alkaline earth metals such as sodium. In contrast to the conventional method, this technology hardly produces unreacted CO<sub>2<\/sub>. Moreover, a crucial factor in the syngas production namely the H<sub>2<\/sub>\/CO ratio is anticipated to be controllable by varying operating conditions such as the hydrogen flow rate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reference<\/strong>\u00a0<\/h3>\n\n\n\n<p>Tomone Sasayama et al, Integrated CO2 capture and selective conversion to syngas using transition-metal-free Na\/Al2O3 dual-function material,\u00a0<em>Journal of CO<sub>2<\/sub>\u00a0Utilization<\/em>\u00a0(2022).\u00a0\u00a0<a rel=\"noreferrer noopener\" href=\"https:\/\/dx.doi.org\/10.1016\/j.jcou.2022.102049\" target=\"_blank\">DOI: 10.1016\/j.jcou.2022.102049<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Development of a transition-metal-free dual-function material for CO2\u00a0capture and reduction to carbon monoxide Efficient capture of even low-concentration atmospheric CO2\u00a0and syngas production without CO2\u00a0separation and purification processes The product gas has an extremely low concentration of impurities, making this a big step towards control of syngas compositions suitable to produce liquid fuels and chemicals Japan [&#8230;]<\/p>\n","protected":false},"author":59,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","nova_meta_subtitle":"A big step towards realization of liquid fuel and chemical production using CO2 as a raw material","footnotes":""},"categories":[5571],"tags":[10744,10416,12366,10630,12450,10743],"supplier":[168,11306],"class_list":["post-124452","post","type-post","status-publish","format-standard","hentry","category-co2-based","tag-carboncapture","tag-circulareconomy","tag-fuels","tag-hydrogen","tag-syngas","tag-useco2","supplier-national-institute-of-advanced-industrial-science-and-technology-aist","supplier-technical-university-of-denmark-dtu"],"_links":{"self":[{"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/posts\/124452","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/users\/59"}],"replies":[{"embeddable":true,"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/comments?post=124452"}],"version-history":[{"count":0,"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/posts\/124452\/revisions"}],"wp:attachment":[{"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/media?parent=124452"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/categories?post=124452"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/tags?post=124452"},{"taxonomy":"supplier","embeddable":true,"href":"https:\/\/renewable-carbon.eu\/news\/wp-json\/wp\/v2\/supplier?post=124452"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
