据报道,甲醇在择形沸石的存在下经历热化学转化为碳2-碳10烃。有研究提出了钌原子在钌铂催化剂体系上的氧化反应。 甲醇是一种有机溶剂,可以在氧化铜/氧化锌/铝2氧3催化剂存在下由合成气合成。由于其高氢碳比、低烟灰生成倾向、相对低的重整温度以及在室温下以液态存在,它是燃料电池技术中氢源的理想候选物。在直接甲醇燃料电池(DMFC)中,

Stainless steel alloys (SS) are increasingly used in food contact applications due to their superior mechanical properties combined with low corrosion rates [1]. Data on metal release (migration) from stainless steel used in transportation or processing containers is nonetheless relatively scarce, in ...
