摘 要：利用碱水解法处理蔗渣原料，分别采用气相色谱（GC）和气相色谱质谱联用仪（GCMS）定量分析碱水解液中的阿魏酸和对香豆酸得率，以确定分析检测方法的优异性。同时，采用先碱水解再酸水解法提取蔗渣中的阿魏酸和对香豆酸，探究萃取溶剂和水解温度对阿魏酸和对香豆酸提取率的影响。结果表明，采用GCMS定量分析碱水解液中阿魏酸和对香豆酸的效果优于GC。与蔗渣的碱水解法相比，先碱水解再酸水解的方法具有更高的分离效率，阿魏酸和对香豆酸得率分别从0.06%和2.00%提高到0.33%和4.04%。与三氯甲烷相比，乙酸乙酯作为萃取溶剂时，阿魏酸得率提高了23.53%，对香豆酸得率提高了6.1倍。蔗渣中阿魏酸酯和对香豆酸酯的水解效率随着水解温度的升高而提高，当温度从25℃升高到60℃，阿魏酸和对香豆酸的得率分别提高5.88%和1.78%。分析结果还表明，蔗渣原料中酯键和醚键分别占对香豆酸总键连的97.27%和2.73%，酯键和醚键分别占阿魏酸总键连的51.51%和48.49%。由此表明，蔗渣原料中对香豆酸主要以酯键与木素/碳水化合物连接，阿魏酸则以酯键和醚键与木素/碳水化合物连接。

Abstract：Sugarcane bagasse was treated with alkaline hydrolysis， and ferulic acid and pcoumaric acid in onestep alkaline hydrolysate were quantitatively analyzed by gas chromatography （GC） and gas chromatographymass spectrometry （GCMS）. Mean while， ferulic acid and pcoumaric acid from sugarcane bagasse were extracted by alkaline hydrolysis followed by acid hydrolysis， and the effects of extraction solvent and hydrolysis temperature on the extraction rate of ferulic acid and pcoumaric acid were investigated. The results showed that compared with alkali extraction， combination of alkali extraction and acid extraction hydrolyzed more pcoumarate and ferulate acids. The yields of pcoumaric acid and ferulic acid were increased from 0.06% and 2.00% to 0.33% and 4.04%，respectively. The yields were also improved with the temperature increasing. When temperature increased from 25℃ to 60℃， yields of ferulic acid and pcoumaric acid were increased by 5.88%and 1.78%，respectively. Compared with using chloroform as extraction solvent， ethyl acetate could increase yields of ferulic acid and pcoumaric acid by 23.53% and 6.1 times， respectively. As a result， it was demonstrated that ester bond was the main linkage between pcoumaric acid to lignin and carbohydrate which accounted for 97.27% of total linkages in sugarcane bagasse. While， both of ester bond and ether bond were the linkages of ferulic acid to lignin or carbohydrate which respectively account for 51.51% and 48.49% of total linkages．

Abstract：In this study， the micronanocellulose（MNC） dispersed in dichloromethane was mixed with polylactic acid （PLA） dissolved in dichloromethane by solution mixing method. The advantages of the composite materials prepared by solution mixing method compared with the melt blending method were analyzed. Further， MNC was modified with silane coupling agent （KH550） to improve the interface compatibility of the composite. The effects of the KH550 amount on the crystal structure of cellulose and the morphology as well as mechanical properties of the composites were investigated. The modified composite material was extruded by twin screw to prepare a wire suitable for FDM type 3D printing. The results showed high content MNC could be mixed with PLA evenly without reducing the mechanical performance of the composite when MNC/PLA composite 3D printing wire was prepared by solution mixing method. 1%of KH550 （on over dried MNC） could effectively improve the interface compatibility of the composite．

Abstract：Regenerated cellulose membranes were prepared in the presence of four types of solvent systems， namely NaOH/urea/thiourea， ［Amim］Cl， ［Amim］Cl/DMF and choline chloride/urea. Regenerated celluloses and regenerated cellulose membranes were analyzed by Fourier transform infrared spectroscopy （FTIR）， Xray diffraction （XRD）， thermogravimetry analysis （TGA）， scanning electron microscope （SEM） and a universal tensile tester. It was found that the crystalline structure of regenerated celluloses transformed from cellulose I to cellulose II. Furthermore， the crystallinity， thermal stability and mechanical strength decreased. Considering the optimum properties of regenerated cellulose membranes and economic cost， the ［Amim］Cl/DMF was the optimal solvent system for preparing the regenerated cellulose membranes．

Abstract：As a biobased environmentfriendly chemical additive，chitosan combined with bentonite（CsBn system）was evaluated as microparticle retention and drainage aid. To explore the performance and the influence factors of the system， the effects of chitosan deacetylation degree （D.D.）and molecular weight （Mη）on the performance of CsBn system were investigated.The efficiency of CsBn system was compared with chitosan single system， cationic polyacrylamide（CPAM）Bn system and CsCPAMBn system. The results indicated that chitosan with low Mη and medium D.D. had the greatest retention and drainage rate in CsBn system， and the higher the D.D. or MV was， the better the paper formation and strength would be. The CsBn system was clearly more efficient in retention, drainage and paper formation than chitosan single system， besides， it could solve the contradiction between high retention and poor formation caused by chitosan single system. Compared with CPAMBn system， the CsBn system could improve the formation by 178.4% and strength by 71.1%. The CsCPAMBn system combined the advantages of Cs and CPAM to achieve higher retention， drainage and better formation．

Abstract：Based on the analysis of the pressure at press section and the principle of squeezing and dewatering in paper machine， it was concluded that the dryness of pressed paper web could be regarded as the energy consumption index of press section， and the linear pressure at the press section and the speed of paper machine were the main factors affecting energy consumption of press section. Combined with the actual production test of the paper machine and the data of pressing dewatering， the test data curve was plotted. The function relation among the linear pressure at press section， paper machine speed and pressed paper web dryness was fitted based on the obtained test data curve. Finally， the energy consumption of press section was optimized by determining the optimal value ranges of linear pressure at press section and paper machine speed． Through analysis and calulation of the test data, the web quality could meet the demand of production, and the eletricity consumption could reduce by 2.1% when the linear pressure at press section and paper machine speed were 90 kN/m and 1075 m/min, respectively.

摘 要：准确预测出水水质对造纸废水处理过程具有重要意义，为此笔者提出一种基于相关向量机（RVM）的软测量模型。首先,利用偏最小二乘法（PLS）提取实际造纸废水处理过程数据的潜变量，解决过程变量的共线性和高维度问题，然后利用潜变量建立RVM预测模型。结果表明，与RVM模型相比，本文提出的PLSRVM组合模型在对出水悬浮固形物（SS）的水质预测测试时，均方根误差降低了7.76%，决定系数提高了12.32%；但对出水化学需氧量（COD）的预测测试效果提升并不明显。此外，PLSRVM模型的预测效果较PLSLSSVM模型有显著提升：对出水SS的预测，均方根误差降低了9.16%，决定系数提高了15.29%；对出水COD的预测结果中，均方根误差降低了9.29%，决定系数提高了18.34%。

Abstract：Predicting effluent quality precisely is important for papermaking wastewater treatment processes. In this paper， a soft sensor model based on relevance vector machine （RVM） was proposed to predict the effluent quality in a papermaking wastewater treatment plant. The proposed method included two steps. In the first step， partial least squares （PLS） method was used to extract the latent variables of the papermaking process data， which could solve the problems of collinearity and high dimensionality in the process variables. A RVM model using the extracted latent variables was developed in the second step. The results showed that the prediction performance of the PLSRVM was better than that of the RVM for the prediction of the effluent quality in a papermaking wastewater treatment plant. With regard to the prediction of effluent suspension solids （SS）， the root mean square error （RMSE） was decreased by 7.76% and the determination coefficient （R2） was increased by 12.32%; however， the prediction results were not improved significantly for the prediction of effluent chemical oxygen demand （COD）. In addition， the prediction performance of the PLSRVM was better than that of the PLSLSSVM model for both the effluent SS and the effluent COD. In terms of the prediction of the effluent SS， the RMSE was decreased by 9.16% and the R2 was increased by 15.29%. In terms of the prediction of the effluent COD， the RMSE was decreased by 9.29% and the R2 was increased by 18.34%.

Abstract：Due to its high efficiency， specificity， mild and environmentalfriendly properties， enzymes have been widely used in food， feed， washing， textile， paper making， leather making， medicine， petroleum and other industries. As a kind of delignification enzyme， laccase is being applied to all aspects of pulping and papermaking processes because of its good effect of delignification. For example， laccase can be used in deinking， biobleaching， stickies removal and paper performance improvement. It has great research and application value because it can improve the physical properties of paper， reduce the dosage of chemicals， production cost and environmental pollution.
Keywords：laccase； deinking； bleaching； stickies removal； paper performance improvement; effluent disposal; biorefinery
