Carbon2Chem® – Technical Center in Duisburg

Abstract

The aim of Carbon2Chem® is to use CO2‐containing top gases from the steel production as a raw material for chemical products. The scientific foundations and tests with synthetic top gases on a laboratory scale have already been investigated. The technical implementation under real top gas conditions is tested in a technical center that was especially built for the project. In the demonstration plants which are directly connected to the integrated steelwork in Duisburg technologies for CO2 reduction are further developed.

Determination of trace compounds and artifacts in nitrogen background measurements by proton transfer reaction time‐of‐flight mass spectrometry under dry and humid conditions

“…The experiments with the PTR‐QiTOF at the steel mill plant of ThyssenKrupp Steel Europe in Duisburg, Germany, before the relocation of the lab container 35 to the Carbon2Chem technical center 55 were carried out with N 2 5.0 (99.999% purity) and N 2 6.0 (99.9999% purity) purchased from Linde Gas, Duisburg, Germany. Prior to the measurements, the setup comprising the calibration gas generator, the transfer line, the multiport valve (MPV), and the PTR‐QiTOF were heated up to the desired temperatures and simultaneously purged for about 30 min with the respective nitrogen gas quality.…”

Decarbonising energy: The developing international activity in hydrogen technologies and fuel cells

“…For the last 200 years, the incumbent, worldwide technology of steel production leads to the continuous emission of copious amounts of CO 2 . Germany has made significant strides in converting steel production units that normally liberate CO 2 to those that liberate only water by using hydrogen instead of carbon to reduce iron oxide [58][59][60] . We note also that the related Swedish project 'Hybrit' ( Hydrogen Breakthrough Ironmaking Technology ) is set to produce the ambitious target of so-called "zero-carbon steel" from 2020 onwards also by using hydrogen instead of carbon as the reactant in the reduction of iron ore to elemental iron [61] .…”

Design and Implementation of a Gas Generating System for Complex Gas Mixtures and Calibration Gases

“…In the gas generating system introduced here, gas mixtures of main and minor components can be enriched with VOCs at trace levels (pptv to ppbv) under dry or humid conditions to simulate gases after a purification process and in order to mimic the measurements conditions at the technical center of Carbon2Chem®. This will enable the study of more realistic deactivation scenarios and help the optimization of the PTR‐TOF‐MS analysis.…”

“…In the envisioned concept of the Carbon2Chem project [1,2], emissions from steel industry are envisaged as raw material for the production of useful chemicals including ammonia (NH 3 ), methanol (CH 3 OH), higher alcohols and polymers using electricity and energy generated from renewable sources [6][7][8][9][10]. Steel mill flue gases are exhaust gases generated during coking and combustion processes.…”
