【摘要】 选择 2 0种中国草本、木本生物质为试样 ,粉碎至 0 .8～ 1.2mm ,在 (110± 5 )℃条件下连续干燥 12h以上 ,取出后立即进行C、H、N元素含量和发热量测定 ,并根据测定结果 ,分别建立了基于C、H元素含量的能量预测经验公式 ,该公式分别通过了α =0 .0 1和α =0 .1检验。研究表明 :生物质的能量大小与其C、H元素的含量呈线性正比关系 ;生物质的发热量随着其氮元素含量的增加呈明显减少趋势 ,但未达到显著水平。更多还原

【Abstract】 In this thesis, the authors choose 20 kinds of Chinese herbaceous and woody biomass as samples, smash to 0.8～1.2 mm size and continually dry above 12 hours in the condition of (110±5)℃, then immediately measure the content and the heat quantity of the element of C, H, N. According to the measurement result, established the energy predict experiential formulations base on the content of the element of C and H, and passed respectively the checkout of α =0.01 and α =0.1. The research indicates that the relationship between biomass energy quantity and the content of C and H shows linearly direct ratio and the heat quantity has an obvious reducing tendency along with the adding content of the N element, but it doesn’t achieve the marked level.更多还原
