由于水和含氧物浓度高，由生物质来源产生的生物油不具有理想的燃料质量。为了改善这些性能，而无需在生产后进行昂贵的升级技术，将微粉化橡胶粉 (MRP) 与南方黄松 (SYP) 以不同的比例共同喂入螺旋反应器内，以生产升级的热解油。事实证明，MRP 可通过降低油中的水含量和含氧化合物的量来提高热解油的热值。为了进一步改善热解油的性能，在原料中添加了氧化镍和碳酸钠。费歇尔滴定显示水含量减少。碳酸钠减少酸的形成。两种催化剂均导致不饱和烃和酚类化合物的形成增加。在生产热解油并增加热值方面，氧化镍优于碳酸钠。
Bio-oil created from biomass sources does not have desirable fuel qualities because of high water and oxygenate concentrations. In an attempt to improve these properties without having to undergo expensive upgrading techniques after production, micronized rubber powder (MRP) was co-fed at various ratios with southern yellow pine (SYP) inside an auger reactor to produce upgraded pyrolysis oil. The MRP proved useful in increasing the calorific value of the pyrolysis oil by lowering the water content and the amount of oxygenates in the oil. To improve the pyrolysis oil properties further, nickel oxide and sodium carbonate were added to the feedstock. Fischer titration revealed a reduction in the water content. Sodium carbonate reduced the formation of acids. Both catalysts caused an increase in the formation of unsaturated hydrocarbons and phenolic compounds. Nickel oxide outperformed sodium carbonate in terms of producing pyrolysis oil with an increased calorific value.
