Membrane-assisted Ethylene Synthesis over Nanostructured Tandem Catalysts

Introduction

MemCat targets to deliver a proof-of-concept for the direct conversion of CO2 to ethylene by realizing tandem catalysts. These catalysts, through nanostructuring, will allow for consecutive CO2-to-methanol and methanol-to-ethylene conversions to occur in the same operational window.

Research Objectives

A fundamental understanding of the parameters governing the reactions will be gained through detailed operando studies of the tandem catalysts. This, in combination with theoretical calculations, will lead to:

1. The underpinning of the reaction mechanism.
2. The rational improvement of the nanostructured catalysts to achieve an industry-relevant level of performance.

Catalyst Deployment

Building on the consortium’s know-how, the catalysts will be deployed in a membrane reactor featuring a combination of tailored nanocomposite membranes. This approach will provide access to ethylene in a selective manner and high yield for the first time.

Science-to-Technology Breakthrough

The MemCat science-to-technology breakthrough will be achieved through a synergy of:

• Synthesis
• Catalysis
• Theory

This will result in the development of novel nanostructured tandem catalysts and the creation of nanocomposite membranes for a prototype catalytic membrane reactor. The goal is to replace current multi-step conversion pathways with existing catalysts.

Long-term Vision

The long-term vision of MemCat is to give access to green e-Polymers by providing carbon-negative plastic precursors using anthropogenic CO2 and green H2. The project will contribute to establishing the EU as the world leader in the use of CO2 as feedstock for chemical production.
