Bridging the Analytical Gap Between Gas Treatment and Reactor Plants in Carbon2Chem®

Abstract

The use of purified process gases as feedstock for subsequent processes requires a detailed verification of the gas purity to ensure long lifetimes of applied catalysts. Herein, the analytical infrastructure for the measurements of the cleaned gases is presented. An overview of all sampling points for the off‐ and on‐line analysis is given. The detailed decryption of the composition of the cleaned blast furnace gas, its main components as well as its traces are presented. Thereby, over 99 % of the overall signal strength of this complex gas matrix measured with a proton transfer reaction mass spectrometer with H3O+ as reagent ion could be revealed. Furthermore, by the example of the catalyst poison H2S, the necessity of monitoring continuously the gas matrix for certain compounds was proven.

Catalytic utilization of converter gas – an industrial waste for the synthesis of pharmaceuticals

“…The function of converter gas in these syntheses is essential to capture and remove the excessive oxygen atoms from the nitro- and carboxylic groups of the reagents. Since the industrial converter gas may contain sulfur-based impurities, 21 we tested the catalytic amidation in the presence of thiophene. Fortunately, this did not lead to poisoning of the catalyst (see ESI, Table S7 † ).…”

The Carbon2Chem® Laboratory in Oberhausen – A Workplace for Lab‐Scale Setups within the Cross‐Industrial Project

“…The analysis of gases is separated into several tasks. Firstly, the investigation of the real gas compositions before and after gas treatment are performed on‐site in Duisburg in the technical center of Carbon2Chem® 12, 13, where we rely on conventional gas chromatography and a proton transfer reaction quadrupole interface time‐of‐flight mass spectromer (PTR‐QiToF‐MS). To establish a solid basis for the latter analytical method, a detailed time‐resolved long‐term analysis method of the different gas compositions was developed 12.…”
