【摘要】 为了提高油泥的热解效率并降低能耗,研究添加不同比例的活性炭对油泥微波热解过程及产物特性的影响,以活性炭作为吸波介质,着重利用气相色谱分析热解产物中的气相组分,利用GC-MS研究热解液相产物.首次完成对油泥热解过程中微波能量利用率的计算.结果发现:当微波辐照功率为800 W时,升温速率为23.4℃/min;添加吸波介质可以使热解的升温速率提高77%以上,热解产物中的固体残留率最多降低24.7%,气体产量最多提高46.9%.此外,不添加吸波介质时,油泥对微波能量的利用率为16.6%;而添加活性炭后,微波能量利用率可以提高12%以上,并且随着活性炭添加量的增大,能量利用率提高.更多还原

【Abstract】 The effect of activate carbon on the pyrolysis behavior of petroleum sludge under microwave irradiation was studied to improve the pyrolysis efficiency of sluge and reduce energy consumption.Activated carbon was taken as microwave absorber.Mainly,gas chromatography(GC)was applied to analyze the gas phase composition of pyrolysis products,and gas chromatograph-mass spectrometer(GCMS)was used to study the pyrolysis liquid products.the utilization ratio of microwave energy in the process of sludge pyrolysis was calculated for the first time.Results showed that the heating rate of petroleum sludge was 23.4 ℃/min when the power of microwave irradiation was 800 W.Through adding microwave absorber,the heating rate of pyrolysis was increased by more than 77%.Meanwhile,solid residues decreased by up to 24.7%,and gas product increased by 46.9% at most.In addtion,without microwvae absorber,the microwave energy utilization of sluge was 16.6%.While it could be increased by more than 12% by adding active carbon.The microwave energy utilization could be improved with the increase of active carbon content.更多还原
