本研究对干橄榄壳和橄榄仁进行了催化和非催化快速热解。采用鼓泡流态化反应器对固体橄榄渣进行非催化处理。为筛选催化剂，在500 °C的固定床小试反应器中对生物质快速热解蒸气进行了原位催化改质。当反应温度为450 °C时，非催化快速热解的生物油产率最高为47.35wt.%(以干生物质计)，而当温度升高到500 °C时，生物油产率下降了37.14wt.%。在固定床单元试验中，使用非催化石英砂可获得最高的液体产率(52.66wt.%)和有机物产率(30.99wt.%)。不同的催化材料，液体产率在47.03~43.96wt.%之间，有机产率在21.15~16.34wt.%之间。添加氧化镁(5%Co)时，干生物质的固体产物由无催化的28.23wt.%提高到32.81wt.%。
In this study, catalytic and non-catalytic fast pyrolysis of dried olive husk and olive kernels was carried out. A bubbling fluidised bed reactor was used for the non-catalytic processing of the solid olive wastes. In-situ catalytic upgrading of biomass fast pyrolysis vapours was performed in a fixed bed bench-scale reactor at 500 °C, for catalyst screening purposes. A maximum bio-oil yield of 47.35 wt.% (on dry biomass) was obtained from non-catalytic fast pyrolysis at a reaction temperature of 450 °C, while the bio-oil yield was decreased at 37.14 wt.% when the temperature was increased to 500 °C. In the case of the fixed bed unit tests, the highest liquid (52.66 wt.%) and organics (30.99 wt.%) yield was achieved with the use of the non-catalytic silica sand. Depending on the catalytic material, the liquid yield ranged from 47.03 to 43.96 wt.% the organic yield from 21.15 to 16.34 wt.% on dry biomass. Solid products were increased from 28.23 wt.% for the non-catalytic run to 32.81 wt.% on dry biomass, when MgO (5% Co) was used.
