Fixed-bed reactor, a process for the preparation of a fixed bed reactor, and use of a fixed-bed reactor

摘要

The present invention relates to a fixed bed 10 for a fixed-bed reactor 100, wherein the fixed bed 10 a particulate support and at least one reactive substance, wherein the carrier has a silica compound, and wherein the eeaktive substance is an organometallic pyridine compound. Furthermore, the invention relates to a process for the production of such a fixed bed, the method comprising the steps of providing a substrate, providing an impregnation and treating the support has with the impregnation. In addition, the invention relates to a gas detection tubes with a correspondingly produced fixed bed, as well as the use of organometallic pyridinium compounds, in particular, pyridinium dichromate in a fixed-bed reactor for the detection of alcoholic compounds, and for the preparation of formaldehyde and / or acetaldehyde.
