近日,中國(guó)石油石油化工研究院提出的“噴氣燃料中抗氧劑和防冰劑含量的測(cè)定”順利通過美國(guó)材料與試驗(yàn)協(xié)會(huì)石油產(chǎn)品和潤(rùn)滑劑技術(shù)委員會(huì)的投票,正式由立項(xiàng)階段進(jìn)入制定階段。這一突破不僅有效提升了噴氣燃料質(zhì)量監(jiān)管水平,助力生物航煤新技術(shù)開發(fā),而且在國(guó)際舞臺(tái)展示了中國(guó)石油的科研實(shí)力和形象,為清潔燃料標(biāo)準(zhǔn)體系建設(shè)貢獻(xiàn)了中國(guó)智慧和中國(guó)方案。
樣品處理
以往,國(guó)際標(biāo)準(zhǔn)規(guī)定的檢測(cè)方法每次只能單獨(dú)測(cè)定抗氧劑和防冰劑含量其中一類的含量,給噴氣燃料產(chǎn)品標(biāo)準(zhǔn)實(shí)施及產(chǎn)品質(zhì)量監(jiān)管帶來了困難。針對(duì)該問題,中石油采用固相萃取-氣相色譜技術(shù)方案,可同時(shí)測(cè)定3種防冰劑和7種抗氧劑,且完全滿足噴氣燃料國(guó)際標(biāo)準(zhǔn)和國(guó)家強(qiáng)制性標(biāo)準(zhǔn)對(duì)防冰劑、抗氧劑含量測(cè)定的要求,填補(bǔ)了相關(guān)標(biāo)準(zhǔn)領(lǐng)域的空白。
