Abstract For converting biomass into renewable fuel, fast pyrolysis and further upgrading processes have been a promising pathway for years. Catalytic deoxygenation of the oxygenate compounds in the pyrolytic bio-oil significantly improves the quality of bio-oil and increases the possibilities of directly using that as transportation fuel. In this study, two types of experiment, fluidized bed fast pyrolysis of Miscanthus and hydro-processing of the produced bio-oil, were conducted in sequence. The Miscanthus biomass was first pyrolyzed to produce the bio-oil in a fluidized bed and the oil product was then hydro-processed into upgraded fuel in a fixed bed reactor over Pd/C catalyst with various operating conditions including reaction temperature, reaction pressure, liquid hourly space velocity (LHSV), and H 2 -to-oil ratio. The chemical compositions, FTIR spectra and physical/chemical properties of the two products were demonstrated and compared. The degree of deoxygenation (DOD) was additionally presented with varying experimental conditions, showing that the maximum DOD of 95% was obtained.

利用农业废弃物快速热解和催化加氢处理生产“插入式”燃料的研究

摘要 多年来，为了将生物质转化为可再生燃料，快速热解和进一步升级过程一直是一个很有前途的途径。热解生物油中含氧化合物的催化脱氧显着提高了生物油的质量，并增加了将其直接用作运输燃料的可能性。本研究依次进行了芒草流化床快速热解和生物油加氢处理两种实验。芒草生物质首先在流化床中热解生产生物油，然后油产品在固定床反应器中在 Pd/C 催化剂上加氢处理成升级燃料，各种操作条件包括反应温度、反应压力、液体时空速度 (LHSV) 和 H 2 油比。证明并比较了两种产品的化学成分、FTIR 光谱和物理/化学性质。脱氧程度 (DOD) 在不同的实验条件下另外呈现，表明获得了 95% 的最大 DOD。
