It serves as the pivotal bridge for turning coal, natural gas, biomass and other carbon resources into fuels and value-added chemicals.<\/p>\n<p>Thanks to their low cost and high yield to fuels, iron-based catalysts now account for more than two-thirds of global FTS capacity.<\/p>\n<p>However, a water-gas shift reaction proceeds almost unavoidably during the iron-catalyzed FTS process &#8212; generating large amounts of carbon dioxide and squandering valuable carbon.<\/p>\n<p>By integrating the syngas with just a bit of methyl bromide at a concentration of five ppm &#8212; the researchers gained surgical control over the reaction pathways on the iron surface.<\/p>\n<p>Experimental data show that such ppm-level methyl bromide switches off the carbon dioxide-forming route, cutting its selectivity from around 30 percent to below 1 percent &#8212; and achieving virtually zero emissions.<\/p>\n<p>FTS has long been a cornerstone of China&#8217;s coal-to-liquid and syngas chemical industries, yet the seemingly unavoidable formation of carbon dioxide by-products remained one of the biggest roadblocks to its green upgrade, said Ma Ding, a professor of Peking University.<\/p>\n<p>&#8220;Our study delivers a simple yet effective technical fix that enables green and low-carbon production of olefins or liquid fuels,&#8221; Ma added.<\/p>\n<p>Paired with renewable hydrogen and low-carbon dioxide coal-gasification, the study is expected to open a fresh pathway in decarbonizing coal-to-liquid or coal-to-chemicals processes.\u00a0 \u25a0<\/p>\n","protected":false},"excerpt":{"rendered":"BEIJING, Oct. 31 (Xinhua) &#8212; A group of Chinese researchers has developed a simple yet highly effective catalytic&hellip;\n","protected":false},"author":2,"featured_media":155345,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[74],"tags":[381,18,19,17,90803,82,90802],"class_list":{"0":"post-155344","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-technology","8":"tag-china","9":"tag-eire","10":"tag-ie","11":"tag-ireland","12":"tag-olefins","13":"tag-technology","14":"tag-zero-carbon"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/115469034990832859","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/155344","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=155344"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/155344\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/155345"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=155344"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=155344"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=155344"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
