【導(dǎo)讀】有一種非催化超臨界醇技術(shù)的系統(tǒng)是使用批處理類型管反應(yīng)器進(jìn)行開發(fā)的。研究了溫度、反應(yīng)時間和酒精-油摩爾比對脂肪酸甲酯產(chǎn)量的影響。結(jié)果顯示，在生物柴油的產(chǎn)量和反應(yīng)時間上超臨界甲醇優(yōu)于超臨界乙醇。而超臨界乙醇反應(yīng)23分鐘只能產(chǎn)生65%。然而，研究表明相比于傳統(tǒng)的催化方。燃料的需求已大幅增加，預(yù)計(jì)在未來二十年內(nèi)，將大大升級。在全球市場石油價格的飆升中發(fā)揮作用。在全球市場中高需求和供應(yīng)有限的化石。燃料供應(yīng)，導(dǎo)致這些能源的價格最近已經(jīng)上漲到前所未有的高度。另一方面，利用這些昂貴的能源已成為環(huán)境污染的主要原因之一。熱，隨后導(dǎo)致全球變暖和酸雨。此外，已發(fā)現(xiàn)廣泛接觸到高濃度的這些有毒氣體。物柴油的甲醇與油生產(chǎn)生物柴油及甘油的反應(yīng)會。最近，異構(gòu)的催化酯交換反應(yīng)相比于均相反應(yīng)的優(yōu)勢已日益受關(guān)注。相反，據(jù)報(bào)在超臨界醇反應(yīng)中水的存在增強(qiáng)。提高生物柴油產(chǎn)量。此外，分離和純化生物柴油相對容易，因?yàn)?
