摘要/Abstract

摘要： 油泥砂是油田开采、运输、冶炼过程产生的危险固体废弃物，造成了大量的土壤、水体和大气污染，热解是实现油泥砂高效转化利用的有效方式之一。利用热重-傅里叶红外联用分析仪（TG-FTIR）开展了油泥砂热特性机理和产物析出特性研究。结果表明：油泥砂热解过程可分为水分和部分轻质组分析出、有机物质析出、碳酸盐化合物分解3个阶段；升温速率的升高，受传热传质影响，油泥砂内部热滞后现象导致热解失重,热重（TG）和微商热重（DTG）曲线整体向高温区移动；热解过程析出CH₄、CO、CO₂、烷烯烃和芳香烃类等可挥发性物质。

Abstract: Oil sludge is one of the major solid wastes generated during oil field exploration, transportation, and petroleum refineries, which can cause severe soil, water, and air pollution. Pyrolysis is an effective technique for reducing oil sludge and achieving energy reutilization. Herein, the thermal characteristic mechanism and precipitation characteristics of oil sludge were studied using thermogravimetric Fourier transform infrared (TG-FTIR) analysis. Results show that the oil sludge pyrolysis process can be divided into three stages, namely, the release of water and a part of the light fraction, the release of organic materials, and the decomposition of carbonate compounds. The increase in the heating rate, affected by the delay in the internal heat and the mass transfer of oil sludge, led to the shift of the TG and derivative thermogravimetry (DTG) curves of the overall pyrolysis weight loss toward the high-temperature zone. Moreover, the pyrolysis process released CH₄, CO, CO₂, and volatile substances such as alkane, olefin, and aromatic hydrocarbons.
