請(qǐng)幫助翻譯下面一段話！非常感謝！ 生物質(zhì)資源總量巨大，但品質(zhì)較低。生物質(zhì)原料中過(guò)多的水分會(huì)延遲熱解反應(yīng)、增加供熱成本和破壞熱解液化產(chǎn)物的穩(wěn)定性。此外，生物質(zhì)還具有親水性強(qiáng)、氧含量高、能量密度低、不易儲(chǔ)存且產(chǎn)地分散等缺點(diǎn)，造成其在運(yùn)輸、儲(chǔ)存以及作為能源利用的成本偏高，進(jìn)而限制了生物質(zhì)利用技術(shù)的進(jìn)一步發(fā)展。基于此背景，本文開展了通過(guò)干燥和烘焙預(yù)處理制備高品質(zhì)生物質(zhì)熱解原料的研究，系統(tǒng)分析了生物質(zhì)干燥過(guò)程的傳熱傳質(zhì)機(jī)理，提出了測(cè)定有效水分?jǐn)U散系數(shù)的簡(jiǎn)便方法，揭示了烘焙三種產(chǎn)物理化特性的變化規(guī)律，明確了干燥和烘焙預(yù)處理對(duì)生物質(zhì)熱解轉(zhuǎn)化的影響。 |

| the total quantity of Biomass resources is huge, but the quality is low. Too much moisture in the biomass raw material delay pyrolysis reaction, increase the cost of heating and destruct the stability of pyrolysis liquefaction product . In addition, the biomass also has strong hydrophilicity, high energy density, low oxygen content, not easy to store and dispersion of origin defects, caused in the transport, storage, and higher costs for energy use, which limits the further development of biomass utilization technology. Based on this background, this paper carried out through drying and roasting pretreatment preparation high quality biomass pyrolysis raw materials research and systematic analysis of the biomass heat and mass transfer mechanism of the drying process, put forward the simple method for determination of effective moisture diffusivity, and reveals the baking three kinds of products, the change rule of physical and chemical properties has been clear about the transformation of drying, and roasting pretreatment on biomass pyrolysis. |
