一种纤维素酶预处理提高氧碱法制桨效果的方法
技术领域
[0001] 本发明涉及一种纤维素酶预处理提高氧碱法制浆效果的方法，其属于制浆造纸技 术领域。
背景技术
[0002] 造纸作为我国传统的轻工业支柱产业之一，随着经济的发展，优质纸产品需求越 来越大，其中传统的林木制浆扮演着重要的角色。然而促进人与自然的和谐发展，经济、人 口、资源、环境相协调发展已势不可挡。保护林木资源的同时要生产出优质纸产品，应从优 化生产工艺，减少生产成本，同时坚持绿色、环保、可持续发展入手。因此非木材资源，以及 相对应的环保制浆造纸技术的研究意义重大。
[0003] 将农业固体废物用来造纸已经成为学者们关注的重点，蔗渣赋有产量大、分布广、 纤维含量较高约5〇%、纤维长度与阔叶木相当等优点，其关注度居高不下;但蔗渣纤维通常 白度低以及强度较差，因此有待通过改善制浆工艺进一步充分发挥其在制浆造纸中的优 势。
[0004] 02与NaOH是氧碱制浆的组重要组成，这是传统碱法制浆以来的一大创新突破，不 仅解决了传统制浆碱耗高、黑液碱回收难、环境污染严重、得率低等问题，它更是一种经济、 高效、环保的制浆方法;结构疏松的草类原料尤为适用，未预处理或是水预处理的蔗渣在氧 碱制浆时碱耗高。
[0005] 纤维素酶主要应用于纤维素水解制单糖，随着生物技术在制浆造纸工业的迅速发 展，在造纸行业中利用纤维素酶预处理纸浆降低纤维分子量，从而降低磨浆能耗并改善纸 浆纤维的性质。TANG Y J等人实验表明，纤维素酶预处理纸浆可以降低33.3%的打浆能耗。 纤维素酶还可以顺利地将油墨从废纸上脱除，同时纤维素酶在酶解造纸污泥中也有广泛的 应用。在氧碱制浆方面，陈克利采用生物预处理蔗渣氧碱制浆，使制浆温度可降至95°C，且 仍有进一步下调氧碱制浆温度的空间与潜力。孙兵采用漆酶对蔗渣原料进行处理，有利于 改善提高原料的制浆特性，提高后续氧脱木素中羟基自由基的脱木素的选择性。氧碱制浆 方法所得纸浆碳水化合物的剥皮反应得以控制，但纸浆得率低、氧化降解严重粘度低等问 题有待进一步解决。
发明内容
[0006]本发明采用纤维素酶对原料预处理，提高了纸浆的得率以及脱木素选择性，在氧 碱制浆过程中减少了纤维的氧化降解，制浆碱耗有所降低，白度也略有提高，满足高品质纸 对纸浆的要求。
[0007]本发明的目的在于提供纤维素酶预处理提高氧碱法制浆效果的方法，主要步骤如 下： (1)绝干原料与水按液比1:4-1:10的比例混合均匀，用浓度为0.01-3 mol/L的稀酸或 稀碱调节液体的pH值为4.5-10.5，然后每克绝干原料加入纤维素酶〇 • 2U-10U的比例添加纤 维素酶，在温度为2〇_6〇°C条件下预处理l5min-36〇min，最后用200-400目的滤网过滤得到 预处理原料，同时回收酶液重复利用； ^ (2) 将预处理原料脱水，脱水后的预处理原料与制浆药液混合均匀送入蒸煮设备，其中 氧碱制衆的条件为:碱量为脱水原料质量的17%-25%，MgS〇4用量为脱水原料质量的〇. 1%— 1%，脱水原料质量浓度8%_15%，氧压0.4-1.0 MPa，30 min-100 min温度升高到80。(1：-105。〇， 保温120 min-240 min，进行氧碱制浆； (3) 蒸煮结束后，将步骤(2)得到的浆料实施喷放处理，然后依传统工艺路线进行洗、 选、筛，其中提取的黑液进入碱回收系统，浆渣回收重新混入待蒸煮原料进行蒸煮，所得细 浆可进行后续漂白处理或根据工厂具体要求做进一步处理。
[0008]本发明所述纤维素酶预处理原料，其纤维素酶是市售的内切0-1，4葡聚糖酶。
[0009]所述原料为非木材纤维蔗渣、稻草、麦草、龙须草等。
[0010] 本发明的有益效果是： (1) 本发明所述原料预处理，有利于原料氧碱制浆性能和纸浆强度性能的改善，降低氧 碱制浆过程中碱耗，属于环保制浆方法； (2) 本发明所述内切纤维素酶是一种从内部切断纤维素链使纤维素降解的酶，在预处 理过程中无需通氧，中性条件下就能有较高的活性，主要作用于不定性区纤维素，对结晶区 纤维降解少，因此能保证了原料的品质，制得的浆强度高，柔软性好； (3) 本发明中纤维素酶预处理后，酶液可以回收重复利用； (4) 本发明所述纤维素酶预处理原料，纤维的空隙变大，孔隙率增加，在氧碱制浆蒸煮 时有利于药液与氧气的渗透，提高蒸煮中自由基的脱木素选择性，提高纸浆得率； (5) 在相同的氧碱制浆条件下，与未用酶处理的对照样相比，其制浆的实际得率提高 1-5 • 5个百分点，纸浆的卡伯值降低1-8个单位，纸浆的白度和黏度略有提高。
