Project description

The aim of this research project is to develop a plasma-assisted methane coupling process using fluidized bed catalysts in the plasma zone. Ethylene will be produced as the main product through non-thermal plasma, and the efficiency of process will be optimized. Tailor made catalytic reactors will be made to increase the plasma-catalyst interaction.

The research tasks of this PhD candidate include:

(1) Design of a plasma fluidized bed reactor

Recently non thermal plasma technology and plasma-catalysis interaction have gained much attention from the chemical industry. Currently, the energy consumption of plasma-catalytic reactor is generally high for chemical conversions such as CH4 coupling and CO2 utilization. A novel catalytic plasma reactor will be developed where catalyst particles will be present in the plasma zone for very short residence time. Several reactor concepts will be investigated. The best configuration will be chosen, a reactor prototype will be built, and it will be used in kinetic studies.

(2) Investigation of methane coupling by non-thermal plasma.

Investigation on the plasma-catalysts interaction in the chosen reactor will be conducted in the methane coupling reaction with or without CO2 addition to the feed. The mechanism, i.e. the discharge characteristics, hydrodynamics, heat transfer and mass transfer will be analyzed to offer a further insight of plasma fluidized beds. The main goal of this task is to improve the energy efficiency of the plasma reactor by achieving better plasma-catalysts interactions. Various plasma discharge types will be explored including Gliding arc discharge, microplasma and dielectric barrier discharges. A conventional micro packed-bed plasma reactor will also be investigated as a benchmark. Diagnostics and characterization of plasma in the developed reactor/system will be performed. The catalyst characterization will be performed before and after reaction.

Project background

CH4 valorization to produce longer C-chain hydrocarbons, and especially ethylene and propylene, which are the building blocks of current petrochemistry (over 200 Mt/y production). Their current production from methane requires a multistep and energy-intensive process: syngas production, methanol synthesis and methanol-to-olefin conversion. Direct conversion of CH4 to these olefins using non-thermal plasma can decrease the carbon footprint by over 60% and thus realize a breakthrough novel process, suitable for example to exploit the large current reserves of stranded gas or shale gas. This project will investigate how new kinds of plasma and their symbiotic interaction with proprietary catalysts can be harnessed to transform the production of longer C-chain hydrocarbons. The plasma process could be powered by renewable energy and working without greenhouse gas emission or waste production, making the process environment-friendly.

This is a multi-disciplinary project and the PhD student will work in close cooperation with other students and a post-doc working on the process design and CFD modelling of reaction kinetics.
