摘要/Abstract

摘要： 采用升流式厌氧污泥床（UASB）处理高盐度稠油采油废水，在HRT≥24h,进水COD浓度为350-640mg/L,原油浓度为112-205mg/L的条件下，COD去除率能够达到65.08%，原油平均去除率达到74.33%。研究结果表明，UASB反应器能够高效处理高含盐采油废水,且反应器内有颗粒污泥形成。采用BP神经网路建立UASB反应器处理高含盐采油废水的数学模型，模拟值与实际出水COD和原油浓度的平均偏差分别为-0.65和0.84%，模型能够很好的模拟和预测UASB反应器的运行效果。

Abstract: Thermal upgrading of vacuum residue mixed with waste plastics was studied in a laboratory scale delayed coking unit. The model of feed thermal decomposition was set up and the first order reaction kinetics was used to predict products distribution during the coking process. The distillate yield was higher (70 %) for the vacuum residue/polystyrene (VR/PS) feed system and the vacuum residue/low density polyethylene (VR/LDPE) feed system. The resulted distillate yield was separated into fractions according to their boiling points, with gasoline and diesel being our fractions of concern. The activation energy was higher for gasoline production (around 60 kcal/mol) varying with the type of feed system, while it was 33 kcal/mol for diesel fraction. The regression coefficient R was 0.990.
