In their work, in order to achieve one-pot hydrolysis of cellulose and hemicellulose in lignocellulosic biomass, freeze pretreatment with 0\u22125 wt % NaOH (3 wt% was chosen as the best concentration) and subsequent microwave-assisted dilute sulfuric acid hydrolysis were applied to tropical plant wastes. Single factor optimization of hydrolysis of the pretreated bagasse was studied, and the best conditions (140 \u00b0C, 30 s, substrate\/solvent ratio of 1\/60 and 0.4 M H2SO4) were further applied to Jatropha and Plukenetia hulls. Under the best conditions, yields of sugars from cellulose (glucose) and hemicellulose (xylose, mannose, and arabinose) in the pretreated bagasse were 84.0% and 92.7%, enhanced by 273.4% and 59.3% as compared with untreated sample, respectively. For the pretreated Jatropha and Plukenetia hulls, yields of glucose and hemicellulose sugars were 85.7% and 93.3% (increased by 225.9% and 75.4%),\u00a0 and 85.0% and 92.9% (increased by 214.8% and 81.4%), respectively.<br \/>\nThe results were published:<br \/>\nTC Su, Zhen Fang*, One-pot microwave-assisted hydrolysis of cellulose and hemicellulose in selected tropical plant wastes by NaOH-freeze pretreatment, ACS Sustainable Chemistry &amp; Engineering, 5(6), 5166\u20135174 (2017).<\/p>\n<p style=\"text-align: justify;\"><strong>\u4e00\u9505\u6cd5\u6c34\u89e3 \u7ecfNaOH \u51b7\u51bb\u9884\u5904\u7406\u540e\u7684\u751f\u7269\u8d28\u4e2d\u7ea4\u7ef4\u7d20\u548c\u534a\u7ea4\u7ef4\u7d20<\/strong><\/p>\n<p style=\"text-align: justify;\">\u00a0 \u6700\u8fd1\uff0c\u82cf\u540c\u8d85\u540c\u5b66\uff08\u4e2d\u56fd\u79d1\u5b66\u6280\u672f\u5927\u5b66\u751f\u547d\u5b66\u9662\u535a\u58eb\u7814\u7a76\u751f\uff09\u5728\u65b9\u8001\u5e08\u7684\u6307\u5bfc\u4e0b\uff0c\u5bf9\u6728\u8d28\u7ea4\u7ef4\u7d20\u4e2d\u7684\u7ea4\u7ef4\u7d20\u548c\u534a\u7ea4\u7ef4\u7d20\u8fdb\u884c\u4e86\u4e00\u9505\u6c34\u89e3\u7684\u7814\u7a76\u3002<br \/>\n\u4e3a\u4e86\u5b9e\u73b0\u6728\u8d28\u7ea4\u7ef4\u7d20\u751f\u7269\u8d28\u4e2d\u7684\u7ea4\u7ef4\u7d20\u548c\u534a\u7ea4\u7ef4\u7d20\u7684\u540c\u65f6\u6c34\u89e3\uff0c\u9996\u5148\u5bf9\u751f\u7269\u8d28\u75280\u22125 wt% NaOH\uff083wt%\u88ab\u9009\u4e3a\u6700\u4f73\u6d53\u5ea6\uff09\u51b7\u51bb\u9884\u5904\u7406\uff0c\u968f\u540e\u8fdb\u884c\u5fae\u6ce2\u7a00\u9178\u6c34\u89e3\u3002<br \/>\n\u5bf9\u9884\u5904\u7406\u540e\u7684\u7518\u8517\u6e23\u6c34\u89e3\u6761\u4ef6\u7684\u4f18\u5316\u8fdb\u884c\u4e86\u5355\u56e0\u7d20\u5b9e\u9a8c\u7814\u7a76\uff0c\u5e76\u5229\u7528\u6240\u5f97\u7684\u6700\u4f73\u6761\u4ef6\uff08140 \u00b0C\uff0c30\u79d2\uff0c\u751f\u7269\u8d28\/\u6eb6\u5242\u6bd4\u4e3a1\uff0f60\u548c0.4 M H2SO4\uff09\u8fdb\u4e00\u6b65\u7528\u4e8e\u5c0f\u6850\u5b50\u548c\u661f\u6cb9\u85e4\u58f3\u7684\u6c34\u89e3\u3002\u5728\u6700\u4f73\u6761\u4ef6\u4e0b\uff0c\u548c\u672a\u7ecf\u5904\u7406\u7684\u6837\u54c1\u76f8\u6bd4\uff0c\u9884\u5904\u7406\u540e\u7684\u7518\u8517\u6e23\u7ea4\u7ef4\u7d20\u7cd6\u4ea7\u91cf\uff08\u8461\u8404\u7cd6\uff09\u548c\u534a\u7ea4\u7ef4\u7d20\uff08\u6728\u7cd6\u3001\u7518\u9732\u7cd6\u3001\u963f\u62c9\u4f2f\u7cd6\uff09\u7cd6\u4ea7\u91cf\uff0c\u5206\u522b\u4e3a84%\u548c92.7%\uff0c\u63d0\u9ad8\u4e86273.4%\u548c59.3%\u3002\u5bf9\u9884\u5904\u7406\u540e\u7684\u5c0f\u6850\u5b50\u548c\u661f\u6cb9\u85e4\u58f3\uff0c\u4ea7\u751f\u8461\u8404\u7cd6\u548c\u534a\u7ea4\u7ef4\u7d20\u7cd6\u5206\u522b\u4e3a85.7%\u548c93.3%\uff08\u5206\u522b\u589e\u52a0225.9%\u300175.4%\uff09\uff0c85%\u548c92.9%\uff08\u5206\u522b\u589e\u52a0\u4e86214.8%\u548c81.4%\uff09\u3002<br \/>\n\u7ed3\u679c\u53d1\u8868\u5728ACS Sustainable Chemistry &amp; Engineering: TC Su, Zhen Fang*, One-pot microwave-assisted hydrolysis of cellulose and hemicellulose in selected tropical plant wastes by NaOH-freeze pretreatment, ACS Sustainable Chemistry &amp; Engineering, 5(6), 5166\u20135174 (2017).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>One-Pot Hydrolysis of cellulose and hemicellulose in Li [&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\/3147"}],"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=3147"}],"version-history":[{"count":1,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts\/3147\/revisions"}],"predecessor-version":[{"id":3149,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts\/3147\/revisions\/3149"}],"wp:attachment":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/media?parent=3147"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/categories?post=3147"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/tags?post=3147"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
