Pre-Combustion

Pre-Combustion Carbon Capture by a Nanoporous, Superhydrophobic Membrane Contactor Process
Project No.: DE-FE0000646


The Gas Technology Institute is developing a pre-combustion carbon dioxide (CO2) separation technology based on a solvent scrubbing process using a novel gas/liquid membrane contactor concept.

The primary goal of the project is to develop a practical and cost-effective technology for CO2 separation and capture from the pre-combustion syngas in coal gasification plants. The specific objective of the project is to (1) develop a membrane contactor module containing a superhydrophobic--extremely difficult to wet--hollow fiber membrane with optimal pore size and surface chemistry, and (2) design the CO2 separation process and conduct an economic evaluation.

PEEK membrane surfaces are hydrophobic and exhibit the same effect as does the lotus plant; that is, the lotus leaf surface is porous and enables transport of CO2 and O2 in wet environments.
