In this study, solid oil palm shell (OPS) waste biomass was subjected to microwave pyrolysis conditions with uniformly distributed coconut activated carbon (CAC) microwave absorber. The effects of CAC loading (wt%), microwave power (W) and N2 flow rate (LPM) were investigated on heating profile, bio-oil yield and its composition. Response surface methodology based on central composite design was used to study the significance of process parameters on bio-oil yield. The coefficient of determination (R(2)) for the bio-oil yield is 0.89017 indicating 89.017% of data variability is accounted to the model. The largest effect on bio-oil yield is from linear and quadratic terms of N2 flow rate. The phenol content in bio-oil is 32.24-58.09% GC-MS area. The bio-oil also contain 1,1-dimethyl hydrazine of 10.54-21.20% GC-MS area. The presence of phenol and 1,1-dimethyl hydrazine implies that the microwave pyrolysis of OPS with carbon absorber has the potential to produce valuable fuel products.
在这项研究中，采用均匀分布的椰子活性炭（CAC）微波吸收剂对固体油棕壳（OPS）废生物质进行微波热解条件处理。考察了 CAC 负载量（wt%）、微波功率（W）和 N2 流速（LPM）对加热曲线、生物油产率及其组成的影响。基于中心复合设计的响应面法用于研究工艺参数对生物油产率的重要性。生物油产率的确定系数（R(2)）为 0.89017，表明数据可变性的 89.017%归因于该模型。对生物油产率影响最大的是 N2 流速的线性和二次项。生物油中的苯酚含量为 32.24-58.09%GC-MS 面积。生物油还含有 1,1-二甲基肼，其 GC-MS 面积为 10.54-21.20%。苯酚和 1,1-二甲基肼的存在意味着 OPS 与碳吸收剂的微波热解有潜力生产有价值的燃料产品。
