“…As part of the Carbon2Chem® project, the plasma‐assisted removal of oxygen traces (DeOxo process) from coke oven gas (COG) is investigated. Coke oven gas is rich in hydrogen (60 %) and has a rather high CO content (10 %), which makes it a promising future feedstock for the synthesis of basic chemicals such as methanol or higher alcohols . O 2 traces must be reduced to a minimum to guarantee the safe operation of downstream processes.…”

The combination of a nonthermal plasma and a heterogeneous catalyst provides unique opportunities for chemical transformations. High densities of reactive species, such as ions, radicals or vibrationally excited molecules, are generated by electron collisions and initiate a multitude of chemical reactions in the gas phase. By shifting the reaction site from the gas phase to the surface of the catalyst, the selectivity of these reactions can be significantly enhanced. Dielectric barrier discharges (DBDs) are a promising plasma source for these kinds of applications due to their non‐equilibrium conditions and their simple construction. This review provides a brief introduction to the breakdown mechanism and the various geometries of DBDs and presents several plasma‐catalytic DBD applications.

“…During the primary steel production route, carbonaceous off-gases are generated during the main production steps of: (1) conversion of coal to coke in the coke oven, (2) pig iron production in the blast furnace and (3) processing of pig iron to steel in the basic oxygen furnace [1]. Since the usage of fossil fuels (usually coal and natural gas) as reducing agents in the blast furnace is intensely optimized [4], alternative ways are investigated for the reduction in those emissions. Generally, a common way to avoid the flaring of Energies 2021, 14, 2904 2 of 24 steelmaking off-gases is their use as internal energy sources both for heating and power production.…”

Integration of Renewable Hydrogen Production in Steelworks Off-Gases for the Synthesis of Methanol and Methane

et al. 2021

The steel industry is among the highest carbon-emitting industrial sectors. Since the steel production process is already exhaustively optimized, alternative routes are sought in order to increase carbon efficiency and reduce these emissions. During steel production, three main carbon-containing off-gases are generated: blast furnace gas, coke oven gas and basic oxygen furnace gas. In the present work, the addition of renewable hydrogen by electrolysis to those steelworks off-gases is studied for the production of methane and methanol. Different case scenarios are investigated using AspenPlusTM flowsheet simulations, which differ on the end-product, the feedstock flowrates and on the production of power. Each case study is evaluated in terms of hydrogen and electrolysis requirements, carbon conversion, hydrogen consumption, and product yields. The findings of this study showed that the electrolysis requirements surpass the energy content of the steelwork’s feedstock. However, for the methanol synthesis cases, substantial improvements can be achieved if recycling a significant amount of the residual hydrogen.

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.
