Fast pyrolysis is a potential technology for converting lignocellulosic biomass into bio-oil. Nevertheless, the high amounts of acid, oxygenated compounds, and water content diminish the energy density of the bio-oil and cause it to be unsuitable for direct usage. Catalytic fast pyrolysis (CFP) is able to improve bio-oil properties so that downstream upgrading processes can be economically feasible. Here, calcium oxide (CaO), magnesium oxide (MgO), and zinc oxide (ZnO) were employed due to their potential in enhancing bio-oil properties. The results showed that overall, all three catalysts positively impacted the empty fruit bunch fibre-derived bio-oil properties. Among the catalysts, CaO showed the most favorable effects in terms of reducing the acidity of the bio-oil and anhydrosugar. Thermal stability of bio-oils produced in the presence of CaO was studied as well.
快速热解是一种将木质纤维素生物质转化为生物油的有潜力的技术。然而，大量的酸、含氧化合物和含水量降低了生物油的能量密度，使其不适合直接使用。催化快速热解（CFP）能够改善生物油的性质，使下游的升级过程在经济上可行。在这里，氧化钙（CaO）、氧化镁（MgO）和氧化锌（ZnO）被使用，因为它们具有改善生物油性质的潜力。结果表明，总的来说，这三种催化剂都对空果串纤维衍生的生物油性质产生了积极的影响。在这些催化剂中，CaO 在降低生物油和无水糖的酸度方面表现出最有利的效果。还研究了在 CaO 存在下产生的生物油的热稳定性。
