Special Issue Information

Dear Colleagues,

Over the past few decades, there have been many advances in the world, leading to the improvement of life quality. Due to demographic and industrial growth, consumption has increased, as well as the amount of wastes and contaminants. Today, global warming and climate change are mainly attributed to the emission of anthropogenic greenhouse gases, with carbon dioxide (CO2) being the most relevant one, due to the huge amount of emissions of this gas to the atmosphere (mainly derived from the consumption of fossil fuels).

Carbon capture and storage (CCS) is a physical process which consists of separating the CO2 (emitted by the industry and by the combustion processes for energy generation) and transporting it to a geological storage to isolate it from the atmosphere in the long term. However, the most promising routes for CO2 mitigation are those that use catalysts and chemical processes for valorization. By applying specific catalysts and suitable operating conditions, CO2 molecules react with other components to form longer chains (i.e., hydrocarbons). Accordingly, efforts should be made to catalytically valorize CO2 (alone or being co-fed with syngas), as an alternative way for reducing greenhouse gas emissions and obtaining high-value fuels and chemicals.

Carbon capture and utilization (CCU) is a developing field with significant demand for research in the following aspects:

  • Development of new catalysts, catalytic routes, and technologies for CO2 valorization;
  • Study of new processes for obtaining fuels and chemicals from CO2;
  • Optimization of the catalyst and the reaction conditions for the process;
  • Steps further on advanced processes for improving the amount of CO2 fed into the reactor (either alone or co-fed with syngas) and the yield of products.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Catalysts is an international peer-reviewed open access monthly journal published by MDPI.

1. Title: Synthesis and characterisation of printed CZZ / H-ZSM-5 catalyst layers for one-stage DME synthesis from carbon dioxide and hydrogen

Authors: Soudeh Banivaheb, Michael Klumpp, Roland Dittmeyer 

Abstract: Dimethyl ether (DME) is considered as both, a new clean fuel and valuable feedstock for chemical industry, which could contribute to a secure energy supply with reduced environmental impact. As part of the so-called Power-to-X concepts, an efficient and compact process for decentralized DME synthesis is needed. Connecting to previous work on the study of bifunctional catalysts for one-stage conversion of synthesis gas into DME at the Institute for Micro Process Engineering, a compact microreactor system is being developed which relies on printed bifunctional catalyst layers allowing for the use of carbon dioxide and hydrogen as the starting materials. For the CO2 activation for to DME CuO/ZnO/ZrO2 (CZZ) catalysts has been synthesized by flame spray pyrolysis (FSP) at different operating conditions of the FSP process. The powders were thoroughly characterized by X-ray diffraction (XRD), N2 physisorprion, reactive N2O chemisorption and H2 temperature-programmed reduction (H2-TPR). Pastes for coating of the CZZ powders, a conventional Cu/Zn/Al2O3 (CZA) methanol synthesis catalyst for reference, and H-ZSM-5 for dehydration of Methanol onto microstructured surfaces by screen printing were developed and will be tested soon. The paper will report the synthesis and characterization of different configurations of bifunctional CZZ / H-ZSM-5 catalyst layers (hybrid and double layer) on microchannel plates and their catalytic performance will be compared.
