Latest development of asymmetric carbon hollow fiber membranes for superior hydrogen purification published in Nature Communications

We successfully developed asymmetric hollow fiber carbon membranes from cellulose precursors. This membrane shows a high H2/CO2 separation performance under the harsh conditions of high-temperature and high-pressure operation. The long-term stability indicates the great potential for hydrogen purification in a steam methane reforming process, which provides an energy-efficient separation technology to expand the hydrogen economy.

carbon hollow fiber membranes for Olefin/paraffin separation

Hollow fiber carbon molecular sieving membranes have the potential application in Olefin/paraffin separation.

the polymeric membranes usually have low selectivity for the gas pairs. while the traditional distillation separation method is energy intensive process for the separation of these mixture with close boiling point and volatility.

carbon membranes have high selectivity based on molecular sieving mechanism. the main challenge is to improve the gas permeance by preparation of asymmetric hollow fiber carbon membranes.

CO2 removal from natural gas

membrane systems has been widely used for CO2 removal from high pressure natural gas processes. however, membrane plasticization at high CO2 concentration is still a challenging issue for most common polymer membranes. how to develop a high performance membrane operated at high pressure is becoming a hot interest for membrane researcher and engineer.
