煤焦油沸腾床加氢工艺的研究

随着经济的发展,国内的资源紧张,再度引起人们对煤焦油加工的关注。煤焦油这种劣质油的生产条件较为苛刻,这对煤焦油的加氢带来了困难,而沸腾床-固定床组合加氢技术比较适合这种劣质油的加工,幵阐述了该工艺收率高、操作平稳、环境污染少的优势。

Research onCoal Tar Ebullated-Bed Hydrogenating Process

With the rapid development of economy and the increasing demand for domestic resources, coal tar processing has been attracted more and more social attention. The processing conditions for coal tar, which belongs to poor quality oil, are comparatively harsh. This brings great troubles to hydrogenation of coal tar. However, the hydrogenation technology combining ebullated-bed and fixed-bed reactors can meet the requirement of processing such poor quality oil.Inthis article, advantages of this technologywere discussed,such ashigh yield, good operation stability o, and low environmental pollution.
