脂肪酶对混合办公废纸脱墨的研究

Enzymatic Deinking of Mixed Office Waste with Lipase

脂肪酶能够水解油墨中的树脂,因此可用于对混合办公废纸进行脱墨。利用Novozymes公司提供的脂肪酶对混合办公废纸脱墨工艺进行优化,结果表明,在适宜的脱墨条件下,50LU/g的脂肪酶,处理60min可使混合办公废纸的脱墨率达到97%。

The lipase can hydrolyze the resin in the ink, which enabled it to deink the mixed office waste(MOW). The objective of this paper was to optimize the deinking process of MOW with one kind of lipase. The result showed that under optimal deinking conditions, the toner particle removal reached 97%。
