Abstract

The use of eucalyptus pelitta (EP) biomass waste and empty fruit bunch of oil palm(EFB) as raw materials for bio-oil is expected to overcome the existing solid waste problems, reduce pollution due to air pollution, and can produce gas and bio-oil which have potential. as new and renewable energy. This study aims to determine the effect of the type of raw material and temperature regulation on the results of pyrolysis products and the characteristics of the resulting bio-oil. The set temperatures used were 300°C, 350°C, 400°C, 450°C, and 500°C with the raw materials being Eucalyptus pellita (EP) bark biomass and empty fruit bunches of oil palm (EFB). Pyrolysis that occurs with the equipment configuration used a heating rate of 7-14°C/minute, where the main reaction of pyrolysis occurs at a temperature of 150°C to 270°C so that the set temperature does not have a large effect on the yield or characteristics of bio-oil. EP pyrolysis produced an average bio-oil yield of 41.64%, while EFB pyrolysis produced an average bio-oil yield of 46.72%. Bio-oil produced by pyrolysis of EP has a characteristic average value for density of 1.062362 gr/mL, viscosity of 2.1749 cP, and pH 2-3. Meanwhile, bio-oil produced by pyrolysis of EFB has a characteristic average value for density of 1.043146 gr/mL, viscosity of 1.3582 cP, and pH 3-4. EP bio-oil has a composition of C7-C10 carbon, while EFB bio-oil has a composition of C6-C19 carbon.

比较热解桉树皮和油棕空果穗生产生物油的效果

使用桉树（EP）生物质废料和油棕空果束（EFB）作为生物油的原料，有望克服现有的固体废物问题，减少空气污染，并能产生气体和生物油，具有作为新能源和可再生能源的潜力。本研究旨在确定原料类型和温度调节对热解产物结果和所产生的生物油特性的影响。所使用的设定温度为 300°C、350°C、400°C、450°C 和 500°C，原料为桉树树皮生物质和油棕空果串。设备配置中的热解采用 7-14°C / 分钟的加热速率，热解的主要反应在 150°C 至 270°C 的温度下进行，因此设定温度对生物油的产量或特性影响不大。EP 热解产生的生物油平均产率为 41.64%，而 EFB 热解产生的生物油平均产率为 46.72%。EP 热解产生的生物油的平均密度值为 1.062362 gr/mL，粘度为 2.1749 cP，pH 值为 2-3。同时，热解 EFB 产生的生物油的特征平均值为密度 1.043146 gr/mL、粘度 1.3582 cP 和 pH 3-4。EP 生物油的碳组成为 C7-C10，而 EFB 生物油的碳组成为 C6-C19。
