Abstract:

通过考察委内瑞拉常渣减黏调和油黏度、密度、残炭和组成的变化,研究了调和油的长期储存稳定性。通过酸值、胶质和沥青质的结构变化,研究了影响调和油长期储存稳定性的因素。结果表明,不同反应条件下的调和油上下层的黏度、密度和残炭差异不显著,基本相同,调和油没有发生分层现象,长期储存稳定性较好,满足船运要求。随着反应苛刻度和储存时间的增加,胶质/沥青质之比减小,调和油的稳定性下降。溶解在调和油中的微量氧与调和油中的自由基和烯烃发生反应,使得酸值增加。储存过程中胶质和沥青质均发生了缩合,不同反应苛刻度下,4个减黏调和油的胶质结构差异并不大,但420℃/30min调和油沥青质的缩合较明显。氧化反应和胶质、沥青质的缩合使得调和油的长期储存稳定性下降。
