新加坡南洋理工大学副教授赖奕章利用废弃的棕榈果外壳和纤维作原料制成了高功能过滤器,以用于净化饮水和空气,其制造费用比一般同类产品低20%。棕榈果的果仁和果肉是制作食用油和香皂等产品的原料,剩下的棕榈果纤维和外壳通常被作为废物抛弃。赖奕章创造了一套新方法,可利用这些废弃物制作过滤器。他先把棕榈果外壳和纤维压成小块,再使用特别器材将其加热,使里边的油分子释放出来,形成一个有许多细孔的活性炭结构,然后将这个炭结构进一步加热,使细孔的直径缩小到几个纳米,形成过滤功能很
Lai Yi-chang, an associate professor at Nanyang Technological University in Singapore, uses waste palm-shell and fiber as raw materials to make high-performance filters that purify drinking water and air, making it 20% cheaper to produce than similar products. The nuts and flesh of palm fruit are the raw materials used to make edible oils and soaps, and the remaining palm fruit fibers and shells are often discarded as waste. Lai Yi Zhang has created a new set of methods that can be used to make filters from these wastes. He first pressed the shell and fiber of the palm into small pieces and heated them with special equipment to release the oil molecules inside to form an activated carbon structure with many pores. The carbon structure was further heated so that the pores The diameter is reduced to a few nanometers to form a filtering function
