摘要能源是國(guó)民經(jīng)濟(jì)建設(shè)和人民生活的重要物質(zhì)基礎(chǔ)，而以石油為主的第三代能源正面臨著枯竭的危險(xiǎn)。人類必須尋找到一種可經(jīng)濟(jì)開(kāi)發(fā)、豐富、清潔的能源。因此，開(kāi)發(fā)與利用新能源和可再生能源，已經(jīng)成為世界性的能源建設(shè)發(fā)展的戰(zhàn)略方向。本文主要是選擇了秸稈作為牲畜飼料、秸稈能源、發(fā)展第三產(chǎn)業(yè)、做有機(jī)肥四種主要利用方法,通過(guò)對(duì)比分析得出了秸稈在這4種主要用途中哪種最為合算。而作為能源方面主要有3種主要加工方法（秸稈固化、秸稈液化、秸稈氣化），通過(guò)各種產(chǎn)出率的比較，結(jié)合我國(guó)國(guó)情，不管從能源利用方面還是利用率來(lái)說(shuō)過(guò)腹還田都是首選，由于發(fā)展第三產(chǎn)業(yè)的最終廢棄物無(wú)法進(jìn)行二次利用所以利用率最低，秸稈作為能源的三種加工方法中，固化成型技術(shù)要求簡(jiǎn)單而且符合我國(guó)當(dāng)前經(jīng)濟(jì)要求，加工成本最低且燃燒廢棄物是上好的有機(jī)肥，秸稈氣化和液化相對(duì)固化來(lái)說(shuō)技術(shù)要求與加工成本設(shè)備等要求比較嚴(yán)格。關(guān)鍵字：秸稈；可再生能源；利用率；固化；液化；氣化1AbstractTheenergyisthenationaleconomyconstructionandthelivesofthepeopleimportantmaterialbase,butisfacingthedangerwhichbythepetroleumthird-generationenergysourcesprimarilydriesup.Thehumanitymustseektoonekindmaytheeconomicaldevelopment,rich,thecleanenergy.Therefore,developsandusesthenewandrenewablesourcesofenergy,alreadybecametheworldwidebasisenergyconstructiondevelopmentthestrategicdirection.Inthispaper,themainusageofstrawasanimalfeed,strawenergy,thedevelopmentoftertiaryindustriesandorganicfertilizerwereseleced,bycomparingtheuseofstrawasanimalfeed,strawenergy,thedevelopmentoftertiaryindustries,andtheorganicfertilizer,themostcost-effectiveonecanbefined.asenergytherearethreekindsofprocessingmethods(strawbriquetting,strawliquefaction,gasificationofstraw),throughavarietyofoutputratesinlightoftheconditionsofourcountry,whetherfromtheuseorutilizationofenergyforthefieldhadbeenfirstchoiceforabdominal,asaresultofthedevelopmentoftertiaryindustrytheultimateuseofwastecannotbecarriedoutsotheutilizationrateofthesecondlowestofthethreetypesofstrawasasourceofenergyprocessingmethods,technicalrequirementsforCuringsimpleandinlinewithChinaseconomicrequirements,theminimumprocessingcostsandwasteburningisagoodorganicfertilizer,strawgasificationandliquefactionoftherelativetechnicalrequirementsforthecuringandprocessingcostsofequipment,suchasmorestringentrequirements.Keywords:Straw；RenewableEnergy；Utilization；briquetting；Liquefaction；gasification2目錄緒論.11我國(guó)秸稈利用發(fā)展背景.12秸稈來(lái)源.43農(nóng)作物秸稈的利用用途.43.1秸稈養(yǎng)畜過(guò)腹還田（約占5%左右）.43.2秸稈作為有機(jī)肥還田利用（約占5%左右）.43.3用于農(nóng)村能源建設(shè)及秸稈發(fā)電（約占21%）.53.4秸稈蘑菇及其他工業(yè)原料（約占3%）.6秸稈能源化.64.1秸稈固體成型（簡(jiǎn)稱生物質(zhì)燃料；俗稱“秸稈煤”）.6秸稈燃料成型后的主要技術(shù)參數(shù)：.6燃燒后廢氣的排放.7有燃煤爐戶可以直接使用生物質(zhì)成型燃料.7生物質(zhì)燃料燃燒后灰分的處理.7生物質(zhì)燃料的特點(diǎn).7秸稈固化燃料的發(fā)展前景8.7秸稈固
