摘要

重质油高温快速热解过程模型对提高产品收率、附加值及降低能耗具有重要意义.利用自动反应网络生成器RMG(reaction mechanism generator)构建重质油高温快速热解的机理模型.选择了分步构建方法,最终合并的模型包含230种物质和1468个反应.采用高频炉对二十烷、十氢萘、乙苯和不同质量比例混合物(二十烷、乙苯和十氢萘)进行快速热解实验验证,结果表明:机理模型可准确模拟出重质油高温快速热解主要气体产物生成结果,当重质油中链烷烃含量较多时和芳烃含量较多时,分别控制温度在1300℃左右和800℃左右有利于乙烯的生产.

Abstract

The modeling of the high-temperature rapid pyrolysis process for heavy oil holds significant implications for enhancing product yields,adding value,and reducing energy consumption.In this paper,we employed the automatic reaction network generator,reaction mechanism generator(RMG),to construct a mechanistic model for the high-temperature rapid pyrolysis of heavy oil.A stepwise construction approach was selected,culminating in a model that encompasses 230 substances and 1468 reactions.Rapid pyrolysis experiments were conducted in a high-frequency furnace by using eicosane,decahydronaphthalene,ethylbenzene,and their mixtures at different ratios to validate the model.The mechanism model can accurately simulate the main gas product generation results of high-temperature rapid pyrolysis of heavy oil.Specifically,when heavy oil contains a higher amount of alkanes or aromatics,maintaining the temperature around 1300℃ and 800℃,respectively,is conducive to ethylene production.
