Superior pulp performance through waste stream recovery

拟议的项目将研究从Canfor纸浆有限公司(CPL)的纸浆厂残渣中回收半纤维素，并随后将其用作纸浆增强剂，以保持CPL作为增强纸浆生产商的领先地位。在第一阶段，将确定从磨渣中提取半纤维素的最佳水解温度、反应时间和化学装载量。随后将全面研究CPL纸浆对半纤维素的吸附与半纤维素浓度、纸浆浓度、时间、温度和pH的关系。将研究这种吸附对纸浆性能的影响，如抗张强度和白度。还将评估使用氢氧化钙、活性碳或漂白程序对水解液进行脱色。该项目将培训4名HQP，支持纸浆厂持续强劲的业绩，从而确保周围社区的健康，并为未来的生物精炼机会奠定基础。

The proposed project will examine the recovery of hemicellulose from Canfor Pulp Limited's (CPL) mill residues and its subsequent use as a pulp strength additive in order to maintain CPL's position as a leading reinforcing pulp producer. During the first phase, the optimum hydrolysis temperature, reaction time, and chemical loading for extraction of hemicelluloses from mill residues will be determined. This will be followed by a comprehensive study of hemicellulose adsorption by CPL pulp as a function of hemicellulose concentration, pulp consistency, time, temperature, and pH. The effects of this sorption on pulp properties such as tensile strength and brightness will be investigated. Decolorization of the hydrolysate using calcium hydroxide, activated carbon, or a bleaching sequence will also be assessed. The project will train 4 HQP, support continued strong pulp mill performance thus ensuring the health of surrounding communities, and establish a foundation for future biorefining opportunities.
