升温速率对稠油氧化特征影响的实验研究
Experimental investigation for effect of heating rate on oxidation characteristics of heavy oil
摘要
Abstract
A study was carried out on the effect of heating rate on the oxidation process of heavy oil,in which the TGA and DSC were used to study the characteristics of heavy oil oxidation.The result shows that with the increase of heating rate,the mass loss rate curve of crude oil moves slightly to the high temperature side,the reaction rate of crude oil oxidation increases,and the time of fuel deposition shortens,which leads to the cracking reaction is incomplete at the stage of fuel deposition.When the Coats-Redfern method is used to calculate the oxidation kinetics parameters of crude oil,it is found that the heating rate has no effect on the selection of the reaction mechanism function,but the results of the activation energy at each oxidation stage are different.The DSC thermograms show that as the heating rate increases,the exotherm of crude oil increases,especially in the high temperature oxidation stage.Thus,it shows that the heating rate has a greater effect on the heavy oil oxidation process.关键词
