The present study deals co-pyrolysis of neem seeds (NM) and waste nitrile gloves (WNG) in a semi-batch reactor with and without catalysts. Results confirmed that the yield of pyrolytic liquid was higher (43.52 wt% at NM: WNG ratio of 3:1) during thermal co-pyrolysis compared to that of catalytic co-pyrolysis (40.42 wt% and 37.14 wt% respectively with CaO and AlO as catalysts). The use of catalysts increased the carbon content, acidity, and heating value and reduced the oxygen content, viscosity, and density of the pyrolytic oil. FTIR analysis suggested the presence of useful functional groups while H NMR analysis confirmed high amounts of paraffin and aromatic compounds in the pyrolytic oil. GC-MS analysis of pyrolytic oil confirmed that blending of NM + WNG and use of catalysts reduced the oxygenated compounds and increased the alcohol and aldehyde thereby enhancing the fuel properties.
本研究在半分批反应器中进行了印楝种子(NM)和废丁腈手套(WNG)的共热解,有无催化剂两种情况。结果证实,与催化共热解相比(分别使用 CaO 和 AlO 作为催化剂时,产率为 40.42wt%和 37.14wt%),热共热解时热解液体的产率更高(NM:WNG 比例为 3:1 时为 43.52wt%)。使用催化剂提高了热解油的碳含量、酸度和热值,降低了氧含量、粘度和密度。FTIR 分析表明存在有用的官能团,而 1H NMR 分析证实热解油中存在大量的烷烃和芳烃化合物。热解油的 GC-MS 分析证实,混合 NM+WNG 和使用催化剂减少了含氧化合物,增加了醇和醛,从而提高了燃料性能。
