摘　　要：丙醛加氢技术有液相加氢与气相加氢两种,国内丙醛加氢技术多为气相加氢。丙醛气相加氢技术又分为列管式固定床与绝热固定床两种。在绝热式固定床中分为单段与多段式两类。本文重点介绍多段式丙醛气相绝热加氢制正丙醇的工艺研究及工业应用情况。There are two kinds of propionaldehyde hydrogenation technologies:liquid phase hydrogenation and gas phase hydrogenation.Most of the domestic propionaldehyde hydrogenation technologies are gas phase hydrogenation.Propanal gas phase hydrogenation.The technology is divided into tubular fixed bed and adiabatic fixed bed.In the adiabatic fixed bed,there are two types:single-stage and multi-stage.Key points of this article.The process research and industrial application of multi-stage gas-phase adiabatic hydrogenation of propanal to n-propanol are introduced.
