生物酶控制纸浆树脂障碍的研究进展

Progress in pitch control in pulp by enzymes

摘要:

在制浆造纸过程中，沉积的树脂会影响纸浆和成纸质量，降低设备的运行效率，最终造成经济损失。由于传统控制树脂障碍的方法不能很好地解决这一问题，因此具有高效催化和无污染的特性的生物酶法在该方面得到快速发展。文中介绍了树脂的成分、存在形式和控制树脂障碍的生物酶，重点介绍了脂肪酶、甾醇酯酶、漆酶和脂氧合酶控制纸浆中树脂障碍的机理和工艺研究方面的进展，指出了生物酶控制树脂障碍技术目前存在的主要问题，提出了该领域的主要研究方向，并对生物酶控制树脂障碍技术进行了展望。

Abstract:

Pitch deposits have negative effects on product quality, machine performance and production line profitability during pulp and paper manufacture. As traditional pitch control technology cannot provide satisfactory solutions in the pitch deposits, the enzymatic treatment has been rapidly developed for its high efficiency and pollution-free property. In this review, the chemical composition and present form of the pitch in pulp is first introduced, followed by a description of the pitch control enzymes. The emphasis is on the current research on enzymatic solutions to pitch problems, including the reaction mechanism, technology, and the present main problems of lipase, sterol esterases, laccase and lipoxygenase. Finally, the technology prospects in this field are proposed.
