Abstract Co-pyrolysis of oily sludge and rice husk was conducted in a fixed-bed reactor to investigate the effects of interactions on the products and improve the quality of the pyrolysis oil. The synergy can be attributed to the catalytic effects of ash and alkali metals derived from biomass. SARA results showed that synergy enhanced the quality of oil product by promoting the content of saturates and aromatics and reducing heavy fractions. Gas chromatography/mass spectrometry results showed that the interaction increased the concentration of chain hydrocarbons and significantly reduced the content of oxygenated compounds by 46–93%. The gas yield was improved due to the promotion of secondary reactions and more H 2 , CO and C 1 –C 2 hydrocarbons were generated. Additionally, though the emission of H 2 S was restrained, the distribution of sulfur in oil and gas phases was promoted.

含油污泥与稻壳共热解提高热解油品质

摘要 在固定床反应器中对含油污泥和稻壳进行共热解，研究相互作用对产物的影响，提高热解油的质量。协同作用可归因于源自生物质的灰分和碱金属的催化作用。SARA 结果表明，协同作用通过提高饱和物和芳烃的含量并减少重馏分来提高油品质量。气相色谱/质谱结果表明，相互作用增加了链烃的浓度，并使含氧化合物的含量显着降低了 46-93%。由于促进了二次反应，产气率提高，产生了更多的H 2 、CO和C 1 -C 2 烃。此外，虽然抑制了 H 2 S 的排放，
