Abstract

The decline in fossil fuel sources is directly linked to the increasing global energy demand, highlighting the urgent need for renewable energy sources. One highly efficient and eco-friendly alternative is bio-oil from co-pyrolysis, a process that effectively breaks down biomass with a high hydrogen index efficiency ratio (H/C). This research comprehensively examines the factors influencing bio-oil production, including the pretreatment of palm fronds with formic acid, the ratio of plastic to palm frond, and the percentage of Ni-CaO catalysts. The study reveals that pretreating the biomass with formic acid and adding low-density polyethylene (LDPE) plastic increase bio-oil yield, while the addition of Ni-CaO catalyst has the opposite effect. These variations notably impact the enhancement of bio-oil quality, as evidenced by calorific value, acid number, density, and bio-oil constituent compounds. Specifically, Bio-oil obtained from OPF prepared with 70% formic acid, 50:50 OPF to LDPE ratio and 15% Ni-CaO catalyst addition yielded 49.6% with an acid number of 8.57 mgKOH/g, density of 0.98 g/mL and heating value of 31.732 MJ/Kg.

使用 Ni-CaO 催化剂催化棕榈叶和塑料废弃物协同热解成液体燃料

化石燃料的减少与全球能源需求的增长直接相关，这凸显了对可再生能源的迫切需求。一种高效且环保的替代能源是共热解产生的生物油，这种工艺能以较高的氢指数效率比（H/C）有效分解生物质。本研究全面考察了影响生物油生产的因素，包括用甲酸预处理棕榈叶、塑料与棕榈叶的比例以及 Ni-CaO 催化剂的比例。研究发现，用甲酸预处理生物质和添加低密度聚乙烯（LDPE）塑料可提高生物油产量，而添加 Ni-CaO 催化剂则效果相反。这些变化显著影响了生物油质量的提高，热值、酸值、密度和生物油成分化合物都证明了这一点。具体来说，用 70% 的甲酸、50:50 的 OPF 与 LDPE 比率和 15% 的 Ni-CaO 催化剂制备 OPF 所获得的生物油产量为 49.6%，酸值为 8.57 mgKOH/g，密度为 0.98 g/mL，热值为 31.732 MJ/Kg。
