Porous Liquids - Incorporation of MOFs and Liquid Polymers

Description:

Organic cages based porous liquid have recently been invented by Prof. James (Publication: nature, 2015, 527, 216).

 

Porous liquids are a new type of liquid absorbent material recently invented at QUB. Because of their fluidity, they can be applied in ways that porous solids cannot, such as in continuous flow gas separations. They are designable, non-corrosive and easily recycled, hence they potentially offer very clear advantages over commercially important amine technology for gas separations. They can be designed to capture one gas over another through the shape, size and related characteristics of the pores.

 

We have executed fit for purpose R&D on these porous liquid materials for the following applications:

 

1) CO2/CH4 separation, compared to the current corrosive and expensive amine technology for carbon capture.

 

2) Desulfurization (‘sweetening’) of natural gas (H2S/CO2/CH4 separation). Natural gas sweetening involves removal of sulphur and CO2 from natural gas and is widely applied in refineries. 40% of current natural gas reserves have levels of H2S and/or CO2 which make their exploitation problematic. Again amine technology is the most widely applied in this application but amines are highly corrosive, toxic and energy-intensive to recycle.
