中国科学技术大学的研究人员发明了一种处理废弃鸡毛的有效方法。据统计,全世界每年产生的鸡毛等禽类羽毛废弃物达500万吨左右。这些废弃羽毛只有少量被制成枕芯、被垫、羽毛扇、羽毛球等,大部分被当作垃圾直接丢弃,不但造成环境污染,还会给人体健康造成危害。而且,废弃羽毛的主要成分为角蛋白,在土壤中不易自行降解,不能直接作为有机肥料使用。中国科学技术大学的研究人员利用超临界二氧化碳体系在600℃的温度下处理3小时,将废弃羽毛转化为碳微球和碳酸氢铵。其中碳酸氢铵可用作肥料和食品添加剂,而且可用于制备氨气。目前使用的哈伯博斯
Researchers at the University of Science and Technology of China invented an effective method to deal with discarded chicken feathers. According to statistics, about 6 million tons of feather waste such as chicken feathers are produced each year in the world. Only a small amount of these abandoned feathers are made into pillows, pads, feather fans, badminton, etc. Most of them are discarded directly as rubbish, which not only causes environmental pollution but also endangers human health. Moreover, the main component of abandoned feathers keratin, not easily degradable in the soil, can not be used directly as an organic fertilizer. Researchers from the University of Science and Technology of China used supercritical carbon dioxide for 3 hours at a temperature of 600 ° C to convert abandoned feathers into carbon microspheres and ammonium bicarbonate. Among them, ammonium bicarbonate can be used as a fertilizer and food additive, and can be used for preparing ammonia gas. Haberboas currently used
