Particle attrition is a major challenge when handling bulk solid materials with fluidized beds due to its ability to cause particle loss. Herein, the particle attrition induced by the gas jets on a perforated plate distributor in a bubbling fluidized bed was investigated for CO₂ adsorbent particles. An attrition tube, which used air as the fluidizing gas, was used as the fluidized bed. At a constant fluidizing velocity, the initial static bed height and orifice gas velocity were considered as variables. It was confirmed that abrasion dominated the particle attrition. The trend indicating the change in the maximum size of the particles (d_pm,a) formed by attrition followed that of the attrition rate (i.e., the formation rate of fine particles via attrition). A new stirring factor that combined the model developed by Werther and Xi with the original stirring factor adequately explained the effect of the static bed height on both the attrition rate and d_pm,a when the initial static bed height was greater than the length of the orifice gas jet that penetrated the bed. The attrition rate increased linearly with the new stirring factor. However, d_pm,a increased exponentially with the new stirring factor. Relationships were successfully proposed to enable the estimation of the attrition rate and d_pm,a for the CO₂ adsorbent particles. This study provided the evidence indicating the significance of the effect of bed height on particle attrition induced by the gas jet on the distributor. Moreover, proper models for correlating the attrition rate and the maximum size of the fine particles formed by attrition in the bubbling fluidized bed were provided.

当使用流化床处理散装固体物料时，由于其引起颗粒损失的能力，颗粒磨损是一项重大挑战。在本文中，研究了在鼓泡流化床中由气体在多孔板分布器上的射流引起的颗粒磨损，以获取CO ₂吸附剂颗粒。使用空气作为流化气体的磨耗管作为流化床。在恒定的流化速度下，初始静态床高度和孔口气体速度被视为变量。证实了磨损占颗粒磨损的主导。表示颗粒最大尺寸变化的趋势（d _pm，a由磨损形成的α）遵循磨损率（即通过磨损形成的细粒的形成率）的速率。将Werther和Xi开发的模型与原始搅拌因子相结合的新的搅拌因子充分说明了静态床高度对初始磨损率和d _pm的影响。孔的气体喷流穿透了床层。磨损率随着新的搅拌因子线性增加。但是，d _pm，a随着新的搅拌因子呈指数增加。已成功提出了关系，以估计CO ₂的损耗率和d _pm，a吸附剂颗粒。这项研究提供了证据，表明床高对气体在分配器上喷射引起的颗粒磨损的影响具有重要意义。此外，提供了用于使起泡流化床中的通过磨损形成的细粒的最大磨损率与最大磨损率相关的适当模型。
