description of the phd projects:

- project #1: phd position on process and energy engineering:

integrated heat exchanger-reactor for the methanation of co2: catalytic reactor design, modelling, and characterisation
the methanation of co2 into ch4 has been studied for decades for its interests both in reducing ghg emissions and providing add-values. nonetheless, one of the key technology barriers exothermic nature of methanation reaction. catalysts (conventionally ni-based) undergoes severe deactivation at high temperatures, preventing their use in long-term, high throughput operations. therefore, proper design of the heat exchanger-reactor for efficient heat removal and reaction temperature control is of vital importance to make this technology truly economically viable for widespread commercialization.
the main objective of the task is to improve fundamental understanding of the methanation reaction by designing, developing and testing of lab-scale catalytic methanation reactors. the main tasks involve: (1) to properly design and fabricate the lab-scale catalytic reactor for methanation; (2 to acquire basic understanding and new physical insights on the methanation reaction by thermodynamics and kinetic studies of the methanation reaction; (3) to experimentally characterize the flow, thermal and catalytic conversion performances of the lab-scale prototypes.

- project #2: microfluidic technology for the intensification of carbon capture and storage process:

the carbon capture and storage (ccs) is considered as a crucial strategy for meeting co2 emission reduction targets. different technologies are actually available for removing large amounts of co2 from natural, refinery and synthesis gas streams. among them, the most mature and widely used technique is the chemical absorption/desorption process using alkanolamine-based solvents. the current involved equipment for co2 absorption/desorption process usually involves towers or packed columns having huge volumes, which are difficult to control and not energy-efficient. one of the routes to realize the co2 absorption/desorption process intensification is through the miniaturization, more precisely the employment of microfluidic devices, providing a largely reduced required volume, enhanced mass and heat transfer, cleaner, safer, higher productivity and more efficient use of energy.
the objective of this phd project is to propose, develop and investigate novel miniature micro-structured devices (absorber) to intensify the co2 chemical absorption process. the major scientific & technological objectives are threefold: (1) to understand the fundamental transport mechanisms for co2 chemical absorption process in microchannels; (2) to design and fabricate laboratory-scale miniature devices for co2 absorption intensification; (3) to characterize the performances of the realized micro-structured co2 absorber using optical-based measurement techniques.

- project #3: design, modeling and performance optimization of thermal energy storage-heat exchanger unit:

the design and development of integrated heat storage-exchanger units have received increasing attention in recent years, mainly for the waste heat recovery both in industries and in buildings. nevertheless, most of the studies are based on conventional concepts (double-tubes, tube-and-fins, compact heat exchanger, plate heat exchanger, etc.) while efficient design of the heat storage-exchanging unit with enhanced thermal performances is still lacking.
this phd project aims at designing and developing innovative, compact and integrated heat storage-exchanger unit with enhanced heat transfer, for the storage and recovery of waste heat from the built-environment (e.g., data centers; sunlight greenhouses, etc.). the advantages expected are multiple: compact, modular, high thermal performances, high volumetric storage capacity and desired transfer kinetic. the dynamic behaviors of the storage unit during the charging/discharging operations and its integration to the built-environment will be particularly addressed.
