EG-AlCl3 pretreatment had an extremely good selectivity for component fractionation, resulting in 88% delignification and 90% hemicellulose removal, with 100% cellulose recovered or 76% (w\/w) cellulose content in solid residue at 150 \u00b0C with 0.055 mol\/L AlCl3. The pretreated residue (5%, w\/v) presented a higher enzymatic hydrolysis rate (glucose yield increased 2 times to 94%) for 24 h at cellulase loading of 10 FPU\/g. The hydrolysis behavior was correlated with the composition and structure of substrates characterized by SEM, FT-IR, BET, XRD and TGA. The enzyme adsorption ability of pretreated straw was 12-folds that for the original sample. EG-AlCl3 solution was further cycled for 3 times with 100% cellulose recovery but only 29% lignin removal\u00a0due to the loss of AlCl3.<br \/>\nThe results were published:<br \/>\nS Tang, Q Dong, Zhen Fang*, ZD Miao, Complete Recovery of Cellulose from Rice Straw Pretreated with Ethylene Glycol and Aluminum Chloride for Enzymatic Hydrolysis, Bioresource Technology, 284, 98\u2013104(<strong>2019<\/strong>).\u00a0<a href=\"https:\/\/doi.org\/10.1016\/j.biortech.2019.03.100\">https:\/\/doi.org\/10.1016\/j.biortech.2019.03.100.<\/a><br \/>\n&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<br \/>\n\u4e59\u4e8c\u9187\u548c\u6c2f\u5316\u94dd\u9884\u5904\u7406\u6c34\u7a3b\u79f8\u79c6\u5b8c\u5168\u56de\u6536\u7ea4\u7ef4\u7d20\u4ee5\u7528\u4e8e\u9176\u6c34\u89e3<\/p>\n<p style=\"text-align: justify;\">\u6700\u8fd1\uff0c\u535a\u58eb\u751f\u5510\u677e\uff08\u7537\uff09\u540c\u5b66\u5728\u65b9\u8001\u5e08\u7684\u6307\u5bfc\u4e0b\uff0c\u5f00\u53d1\u51fa\u4e00\u79cd\u65b0\u578b\u7684\u5e94\u7528\u4e8e\u6728\u8d28\u7ea4\u7ef4\u7d20\u751f\u7269\u8d28\u7684\u4e59\u4e8c\u9187-\u6c2f\u5316\u94dd\u9884\u5904\u7406\u6280\u672f\uff0c\u5176\u5bf9\u6728\u8d28\u7ea4\u7ef4\u7d20\u7ec4\u5206\u5206\u79bb\u5177\u6709\u6781\u597d\u7684\u9009\u62e9\u6027\u3002\u5728150 \u00b0C\u548c0.055 mol\/L AlCl3\u6761\u4ef6\u4e0b\uff0c\u6c34\u7a3b\u79f8\u79c6\u4e2d\u7ea4\u7ef4\u7d20\u88ab100%\u4fdd\u7559\uff0c88%\u7684\u6728\u8d28\u7d20\u548c90%\u7684\u534a\u7ea4\u7ef4\u7d20\u88ab\u53bb\u9664\u3002\u540c\u65f6\uff0c\u56fa\u4f53\u6b8b\u6e23\u4e2d\u7ea4\u7ef4\u7d20\u542b\u91cf\u8fbe\u523076%\uff0c\u4e14\u572810 FPU\/g\u548c5%\u57fa\u8d28\u6d53\u5ea6\u6761\u4ef6\u4e0b\uff0c\u9176\u6c34\u89e324 h\u540e\uff0c\u9176\u89e3\u7387\u8f83\u539f\u59cb\u6c34\u7a3b\u79f8\u79c6\u63d0\u9ad82\u500d\uff0c\u8fbe\u5230\u4e8694%\u3002\u901a\u8fc7SEM\u3001FT-IR\u3001BET\u3001XRD\u548cTGA\u7b49\u6280\u672f\u624b\u6bb5\u8868\u5f81\u4e86\u6c34\u7a3b\u79f8\u79c6\u7684\u7ec4\u6210\u7ed3\u6784\u548c\u5176\u53ef\u9176\u6c34\u89e3\u80fd\u529b\u7684\u5173\u7cfb\u3002\u6c34\u7a3b\u79f8\u79c6\u7ecf\u9884\u5904\u7406\u540e\uff0c\u5bf9\u7ea4\u7ef4\u7d20\u9176\u7684\u5438\u9644\u80fd\u529b\u63d0\u9ad8\u4e8611\u500d\u3002\u6b64\u5916\uff0c\u4e59\u4e8c\u9187-\u6c2f\u5316\u94dd\u6eb6\u6db2\u7528\u4e8e\u6c34\u7a3b\u79f8\u79c6\u5faa\u73af\u5904\u74063\u6b21\uff0c\u5747\u4fdd\u6301100%\u7ea4\u7ef4\u7d20\u56de\u6536\u7387\uff0c\u4f46\u7531\u4e8e\u5faa\u73af\u5904\u7406\u671f\u95f4AlCl3\u7684\u635f\u5931\uff0c\u6728\u8d28\u7d20\u8131\u9664\u7387\u964d\u81f329%\u3002<\/p>\n<p style=\"text-align: justify;\">\u7ed3\u679c\u53d1\u8868\u5728Bioresource Technology: S Tang, Q Dong, Zhen Fang*, ZD Miao, Complete Recovery of Cellulose from Rice Straw Pretreated with Ethylene Glycol and Aluminum Chloride for Enzymatic Hydrolysis, Bioresource Technology, 284, 98\u2013104 (<strong>2019<\/strong>).\u00a0<a href=\"https:\/\/doi.org\/10.1016\/j.biortech.2019.03.100\">https:\/\/doi.org\/10.1016\/j.biortech.2019.03.100<\/a>\u00a0(Q1, IF 5.8).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Complete recovery of cellulose from rice straw pretreat [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts\/3649"}],"collection":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/comments?post=3649"}],"version-history":[{"count":6,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts\/3649\/revisions"}],"predecessor-version":[{"id":4080,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts\/3649\/revisions\/4080"}],"wp:attachment":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/media?parent=3649"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/categories?post=3649"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/tags?post=3649"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
