FIXED-BED REACTOR, METHOD FOR PRODUCING A FIXED-BED REACTOR, AND USE OF A FIXED-BED REACTOR

摘要

A fixed bed (10) is provided for a fixed-bed reactor (100). The fixed bed (10) contains a particulate carrier and at least one reactive substance. The carrier is a silicate compound and the reactive substance is an organometallic pyridine compound. A method for preparing such a fixed bed is provided. The method includes the steps of preparing the carrier, preparing an impregnation and treating the carrier with the impregnation. In addition, a gas-measuring tube is provided with a correspondingly prepared fixed bed as well. A method uses organometallic pyridinium compounds, especially pyridinium dichromate, in a fixed-bed reactor for detecting alcohol compounds and for preparing formaldehyde and/or acetaldehyde.
