摘要

采用精确控温的固定床反应装置研究了罐底油泥和清罐油泥在不同升温速率下热解产物特性。结果发现当升温速率为5℃·min-1和2℃·min-1时，两种油泥样品的油品回收率均高于65%。提高升温速率有利于促进气相产物的生成，同时得到的油相产物中环状有机物含量提高而链状有机物含量减少，这说明提高升温速率有助于C-H键断裂和环化反应的发生。借助于TG分析和Doyle方程得到两种油泥的热解反应动力学参数。发现随着升温速率加快，表观反应活化能增大了20%~37%。

Abstract

The pyrolysis characteristics of petroleum sludge samples collected from crude oil tank and cleaning water reservoir under two slow heating rates (5℃·min-1 and 2℃·min-1) were experimentally studied in a fixed bed reactor. Thermogravimetric analysis was carried out for deducing reaction kinetics based on Doyle equation. Results show that around 65% of oil can be recovered through pyrolysis and the fraction of cyclic compounds increased with heating rate caused by enhanced C-H bonds breaking and cyclization reactions. Moreover

the apparent activation energy grows 20%-37% with higher heating rate.
