Sorption Enhanced Mixed Matrix Membranes for H2 Purification and CO2 Capture

The goal of this project is to develop sorption enhanced mixed matrix membranes with H₂ permeance of 500 gas permeance units (gpu) and H₂/CO₂ selectivity of 30 at 150-200 °C. 

Overview

These membranes will be the central component in the design of membrane‑based systems for 90% capture of CO₂ from coal-derived syngas, with 95% CO₂ purity at a cost of electricity 30% less than baseline capture approaches. In this project, Pd nanoparticles are synthesized and dispersed in the polymer matrix to provide high H₂ solubility and permeability. This project is funded by the Department of Energy National Energy Technology Laboratory.
