The proposed research is aimed at evaluating the effect of steam treatment on the pellet quality as well as developing a robust method to determine chloride levels in the feedstock from BC coasts. Wood pellets, despite their high density, tend to disintegrate easily into fines due to moisture sorption and mechanical handling. Fines accumulation can lead to explosion, off-gassing and self-combustion, threatening the occupational health and safety of the workers. The proposed research investigates the use of steam pre-treatment of biomass feedstock to improve pellet quality in terms of mechanical strength and moisture proofing. Another aspect of this research is developing a screening method for feedstock to separate low salt content (<200 ppm) feedstock from high salt content feedstock. The detailed objectives of this research are to (1) quantify the effect of steam-treatment on durability of pellets made from coastal wood species and to (2) develop a method for fast measurement of chloride content of feedstock. Our target is to provide data to help TimberWest to develop a profitable and sustainable wood pellet operation. The proposed research contributes to the advancing of science and engineering of biomass densification through preparing highly qualified graduate engineers and scientists. We plan the following approaches towards meeting the objectives of the proposed research:

拟议的研究旨在评估蒸汽处理对球团质量的影响，并开发一种可靠的方法来确定BC海岸原料中的氯化物水平。木质颗粒尽管密度高，但由于吸湿和机械处理，往往容易分解成细粉。粉尘积聚会导致爆炸、排气和自燃，威胁工人的职业健康和安全。拟议的研究调查使用蒸汽预处理生物质原料，以提高颗粒质量的机械强度和防潮。本研究的另一个方面是开发一种用于原料的筛选方法，以将低盐含量（<200 ppm）原料与高盐含量原料分离。本研究的具体目标是：（1）量化蒸汽处理对沿海树种制成的颗粒耐久性的影响;（2）开发一种快速测量原料中氯化物含量的方法。我们的目标是提供数据，以帮助TimberWest开发一个有利可图的和可持续的木屑颗粒业务。拟议的研究有助于通过准备高素质的研究生工程师和科学家推进生物质致密化的科学和工程。我们计划采取以下方法来实现拟议研究的目标：
