Adaptable Reactors for Resource- and Energy-Efficient Methane Valorisation (ADREM) responds to the EU Horizon 2020 call SPIRE-05-2015 and is a research and innovation project. ADREM's main goal ist the development of a highly innovative, economically attactive and rescource- and energy-efficient valorisation process of variable methane feedstocks to higher hydrocarbons and liquid fuels.
About the project
ADREM is dedicated to innovation in resource and energy efficiency in process industries. In four years, a consortium of 10 European organizations, led by TU Delft, will focus on the development of new and intensified adaptable catalytic reactor systems for flexible and decentralized production at high process performance. The reactors should be able to operate with changing feedstock compositions and deliver on-demand the required product distribution by switching selected operational parameters and/or changing modular catalyst cartridges. In the long term, the reactors are expected to operate energy- and emission-lean using green electricity as the direct, primary energy source.
The societal importance of methane as the source of energy and chemicals in the coming decennia cannot be overestimated. The enormous reserves, its potential contribution to improved environmental sustainability, and lower overall costs point to natural gas as the dominating primary source for energy and chemicals in the near future. Small natural gas reservoirs, shale gas, coalbed methane, agricultural biogas and deep-sea methane hydrates contribute to the great diversity of methane sources. This diversity creates a need to develop modular, flexible catalytic reactor systems capable of valorizing methane to longer hydrocarbons and of operating with changing methane feedstocks in various environments.
ADREM will provide highly innovative, economically attractive and environmentally friendly processes and equipment for efficient transformation of methane into valuable chemicals and liquid fuels to be run in the long term on green electricity. Monetary savings of more than 10% compared to conventional centralized processes are targeted. Technologies based on recent research in process intensification will be developed applying flexible modular one-step process with high selectivity for valorisation of methane from various sources. Modular (containerized and mobile) reactors will be provided permitting flexible adaptation of the plant size to demand and also utilizing smaller or temporary sources of methane or other feeds. Innovative reactor types investigated within the project include microwave/radiofrequency, non-thermal plasma, gas−solid vortex reactor, and high-temperature gradient micro-plasma reactors with structured catalyst packed bed.
Figure 1: The overall approach of ADREM
ADREM addresses current and future important societal challenges. Novel reactor systems developed in the project will provide indeed novel means for the conversion of methane in cases when it presently has to be flared or released because of lacking or non-economic connections to gas pipelines. This presents a strong positive environmental impact, which will be increased even further when using renewable electricity as a source for operation of the new reactors.
1. Reactor development of microwave heated catalytic systems for enhanced methane nonoxidative coupling processes
The main goal of this work package is to develop novel microwave heated reactors capable of enhancing conversion (at a given gas phase temperature) and selectivity of methane into added value chemicals (C2 light hydrocarbons, oligomers, aromatics) via a non-oxidative coupling reaction mechanism.
2. Development of plasma-activated (catalytic) systems for enhanced methane coupling processes
The aim of this WP is to develop novel plasma-activated reactors capable of enabling methane coupling into added value chemicals (C2 hydrocarbons, oligomers, aromatics) at milder process conditions and with better yields compared to conventional thermal processing.
3. Reactor development concept: Gas–Solid Vortex Reactor in a Static Geometry
The objective is to show that the selectivity for the oxidative coupling of methane (OCM) towards C2products can be improved in a gas–solid vortex reactor in a static geometry (GSVR–SG) as compared to a traditional fixed-bed type reactor.
4. Reactor development concept: high-temperature gradient (HTG) reactor
The main feature of the proposed reactor concept will be the internal (radial) temperature gradient (HTG). The reactor will be devised in a tubular fashion, the external surface being either exposed to ambient air or cooled additionally; nonetheless, it will in any case serve for the vertical product condensate removal by the force of gravity alone or, perchance, by adequately refining the condensing interface structure rendering it lamellar to decrease the liquid/solid surface tension. Whereas HTG will provide a continuous liquid product removal on the outer reactor jacket, the central reactor axis is to be devoted to plasma source.
5. Catalyst development
The aim of this catalyst development work package (WP5) is provide each reactor work package (WP1-4) with an appropriate catalyst for each stage of the reactor comparison and down-selection.
6. Concept evaluation and selection
The aim of this WP is to evaluate the different new reactor concepts consistently and systematically by comparing these to the state of the art conventional reactor concepts and the current best available technology to convert methane into chemicals. The experimental results and literature data that are obtained in the reactor concept development work packages (WP1-4) serve as the basis for the analysis of the reactor performance The development of models suited to assess the performance of these reactors in a larger process scheme and extract the key performance indicators allows the evaluation of the new concept reactors and the corresponding chemistries in view of meeting the main objectives (selectivity, productivity etc…). Further, the integration of the novel reactors with upstream and downstream equipment, the adaptability to changing feedstock and product specifications as well as the modularization of the complete conversion chain will be analysed. On this basis, the 2 most promising concepts will be chosen for demonstration at TRL5. Finally the full techno economics of the modularized methane valorisation process train will support the generation of the business model and the roadmap for following development and demonstration activity.
7. TRL5 validation of selected concept
The aim of this WP is testing and validation of the selected reactor concepts developed and selected in WP1-6 at TRL 5.
