Effect of varying Cinnamomum camphora leaf powder content on the pelletizing quality of bamboo fiber biomass pellets for renewable energy applications

Addressing the issue of low effective utilization of moso bamboo in Zhejiang Province, this study investigated the impact of varying camphor leaf powder content on the granulation quality of bamboo fiber biomass pellets, using moso bamboo fibers and camphor tree leaves from Zhejiang as raw materials. Experimental analysis examined moisture content, mixing ratio, and molding pressure effects on pellet density and mechanical durability. The experimental results revealed that under the same conditions, the performance of bamboo fiber pellets without camphor leaf powder is significantly inferior to those containing camphor leaf powder. As moisture content rose from 3% to 9%, pellet density and durability increased, but further increases to 18% led to their decline. Orthogonal experiments demonstrated that both moisture content and molding pressure had significant effects on density and mechanical durability. The calorific value test results indicated that the higher heating value of the mixed pellets reached 4380 Kcal/kg. The findings of this study provide insights for enhancing the utilization efficiency of moso bamboo and camphor tree leaf resources.
