This study investigated the catalytic co-pyrolysis of sugarcane bagasse (SCB) and waste high-density polyethylene (HDPE) over faujasite-type zeolite derived from electric arc furnace slag (FAU-EAFS) in a fixed-bed reactor. The effects of reaction temperature, catalyst-to-feedstock ratio, and HDPE-to-SCB ratio on product fractional yields and chemical compositions were discussed. The co-pyrolysis of SCB and HDPE over FAU-EAFS increased the liquid yield and enhanced the quality of bio-oil. The maximum bio-oil (68.56 wt%) and hydrocarbon yield (74.55%) with minimum yield of oxygenated compounds (acid = 0.57% and ester = 0.67%) were achieved under the optimum experimental conditions of catalyst-to-feedstock ratio of 1:6, HDPE-to-SCB ratio of 40:60, and temperature of 500 °C. The oil produced by catalytic co-pyrolysis had higher calorific value than the oil produced by the pyrolysis of SCB alone.
本研究在固定床反应器中用电弧炉渣衍生的丝光沸石（FAU-EAFS）对甘蔗渣（SCB）和废高密度聚乙烯（HDPE）进行共热解，考察了反应温度、催化剂与原料比以及 HDPE 与 SCB 比对产物得率和组成的影响。FAU-EAFS 上 SCB 和 HDPE 的共热解增加了液体产率，提高了生物油的质量。在催化剂与原料比为 1:6、HDPE 与 SCB 比为 40:60、温度为 500°C 的最佳实验条件下，可获得最大生物油（68.56wt%）和烃类产物收率（74.55%），含氧化合物（酸=0.57%，酯=0.67%）的产率最低。与单独热解 SCB 相比，催化共热解产生的油具有更高的热值。
