乙醇燃料中Fe元素检测方案(ICP-AES)

Fossil fuels have been the main source of energy in industrial applications and transportation for decades. However, depleting reserves, environmental concerns and economic issues have led to the development of renewable, cheaper and cleaner alternatives. Bio-ethanol is one of those alternatives and is derived by fermenting the sugar and starch components of plant byproducts. Different purities of bio-ethanol are used as fuel sources. Hydrated ethanol fuel has not had treatment to remove moisture and contains between 93-96% ethanol. It is often used in flexible (flex-fuel) or dual fuel engines. Anhydrous ethanol has been treated to remove moisture and has a purity of at least 99%. It is blended at up to 25% v/v with gasoline. High purity fuel can be contaminated with elemental impurities during production, stockpiling and transportation, so accurate quantitation of metal content is important. According to ASTM D4806 specification [1] and the Brazilian National Agency of Petroleum, Natural Gas and Biofuels 2 (ANP) Resolution number 19/2015 [2], the presence of Cu, Fe, Na and S in ethanol must be controlled. Limit concentrations for Cu are 0.1 and 0.07 mg/kg (ASTM and ANP respectively), 5 mg/kg Fe (ANP), 2 mg/kg Na (ANP), and 30 mg/kg S (ASTM). In this study, the accuracy, precision and long term stability performance of the Agilent 5100 Synchronous Vertical Dual View (SVDV) ICP-OES was evaluated for the determination of Cu, Fe, Na and S in ethanol fuel samples according to ASTM D4806 and ANP Resolution 19/2015 methods.

ALD在钙钛矿方面的应用

“碳达峰”和“碳中和”一直都是能源领域的热点话题,作为助力“双碳”战略的生力军,光伏产业具有举足轻重的地位。目前光伏的主力是硅太阳能电池,它们具有效率高、稳定性好、产业链完备、使用寿命长的优势。然而,晶硅电池的转换效率到达瓶颈,且从硅料到组件至少经过4 道工序,单位制程需要3 天以上,同时还需要大量人力、运输成本等。为了让太阳能的利用更加便捷、高效且廉价,科学界和工业界正在研制新型太阳能电池;钙钛矿太阳能电池就是备受关注的后起之秀,钙钛矿叠层效率极限可达50%,而钙钛矿组件在单一工厂完成生产,原材料经过加工后直接成组件,没有传统的“电池片”工序,大大缩短制程耗时。但是,如何制备大面积且能保持较高效率的钙钛矿太阳能电池,依然是难题,也成了制约其产业化应用的瓶颈。 原速ALD在钙钛矿电子传输层、空穴传输层、钝化层、封装阻水层等领域已取得了突破性进展,获得了业界的认可。为了更高效地服务于世界光伏产业高地,原速也在上海建立了技术研发中心。截止目前,公司已形成服务于钙钛矿电池研发、中试、100MW、 GW级量产的产线ALD技术解决方案。
