毕业设计说明书（论文）中文摘要2,3-丁二醇是一种常见的化学物质，分子式为C4H10O2。常温下为无色黏稠状液体，低温下为晶体。可溶于水，溶于醇和醚。可作为吸湿剂、增塑剂和偶联剂。在如今随着现代化的逐步发展，各方面的生产生活急需能源加持，而如今面临的窘境就是能源的缺乏，不论是化石能源还是其他，在如此能源供不应求的环境下，增添一种能源新方法就显得格外重要了，这种方法就是利用可再生的生物质资源作为原料，将其结合生物或者化学等集成方法来产生化学品，其原理就是利用生物炼制技术，用糖质为原料来转化，产生生产化学品核心如2,3-丁二醇等。这种技术在未来将会逐渐受到国内外企业的推崇，故而越来越受到关注。2,3-丁二醇的生产有多种途径，本工厂设计采用玉米秸秆为原料，年产2万吨燃料丁二醇，通过查阅资料以及询问指导老师，关注丁二醇的发展近况，并且计算出原料设备等一系列数据，结合实际情况完成本次设计。关键词2,3-丁二醇，玉米秸秆，糖化发酵，可持续发展毕业设计说明书（论文）外文摘要TitleDesignof20000t/afuelbutanediolfermentationfactoriesAbstract2,3-butanediolisachemicalsubstancewiththemolecularformulaC4H10O2.Acolorlessviscousliquid,crystallineatlowtemperatures.Canbemisciblewithwater,solubleinalcoholandether.Canbeusedasahygroscopicagent,plasticizerandcouplingagent.Inincreasingenergydemand,thegrowingshortageoffossilenergy,petroleumresourcessupplyunstableconditions,withrenewablebiomassresourcesasrawmaterial,throughchemical,biologicalandintegratedmethodsintheproductionofvariouschemicals,functionalmaterialsandenergymaterialofbiologicalrefiningtechnologyreceivesincreasingattentionfrombothathomeandabroad,especiallyinsugarasrawmaterialsusingbiotransformationtechnologytoproduceimportantbiologicalbasechemicalssuchas2,3-butanediol,isoneoftheresearchdirectionofconcern.Therearemanywaystoproduce2,3-butanediol.Thisdesignusescornstrawasrawmaterial,withanannualoutputof20,000tonsoffuelbutanediol.Byconsultinginformationandaskingguidanceteachers,itpaysattentiontotherecentdevelopmentofbutanediol,andcalculatesaseriesofdata,suchasrawmaterialsandequipment,tocompletethedesigncombinedwiththeactualsituation.Keywords2,3-butanediol,cornstraw,diastaticfermentation,sustainabledevelopment淮阴工学院毕业设计说明书（论文）第I页共II页目录1引言.............................................................11.1合成方法.......................................................11.1.1化学法.......................................................11.1.2生物转化法...................................................21.2本课题设计任务.................................................22设备与流程.......................................................22.1材料选择.......................................................22.1.1菌种与培养基.................................................32.1.2原材料.......................................................32.1.3仪器设备.....................................................42.2流程简介.......................................................43物料衡算.........................................................53.1工艺技术指标及基础数据.........................................53.2发酵车间物料衡算...............................................53.320000t/a2,3-丁二醇厂发酵车间的物料衡算表.......................74主要设备的设计和选型.............................................84.1发酵罐.........................................................84.1.1发酵罐的选型.................................................84.1.2生产能力、数量和容积的确定...
