DESCRIPTION:Prof. Wendy Queen\nProf. Kumar Agrawal\n\n\nHighly porous adso
 rbent materials for the separation of CO2 from dilute gas streams\nPresen
 ted by Prof. Wendy Queen\, Associate professor and head of the Laboratory 
 of Functional Inorganic Materials\, EPFL\n\nThe chemical industry consumes
  ~10 to 15% of global energy in separation processes alone\, and this perc
 entage will increase with the implementation of large-scale carbon capture
  efforts\, an event that is partly constrained by the lack of a viable sol
 ution to separate CO2 from dilute gas streams. Given this\, the developmen
 t of new porous adsorbents\, able to efficiently remove CO2 from gas strea
 ms and/or help reduce the energy consumption of other separation processes
 \, is poised to reap huge global benefits through both cost and energy sav
 ings and an overall improvement in environmental and human well-being.\n\n
 \n\nIn this presentation\, a general introduction to targeted classes of p
 orous adsorbents will be given. Moreover\, the presentation will outline o
 ur recent work on the design of several novel\, highly porous adsorbents\,
  their assessment in CO2 capture applications\, and the construction of a 
 CO2 capture demonstration unit that will be installed in Valais in 2024. 
 \n \n\n\nEnergy-efficient and low-cost carbon capture from atom-thick fil
 ms\nPresented by Prof. Kumar Agrawal\, Associate professor and Gaznat Chai
 r for Advanced Separations\, EPFL\nEnergy-efficient and low-cost carbon ca
 pture from point source emission is crucial for rapid proliferation of cap
 ture technology needed to reduce anthropogenic CO2 emission. We focus on e
 ngineering ultrathin films\, down to the thickness of a single atom\, whic
 h selectively remove CO2 from N2. In this seminar\, I will present synthes
 is and scale-up of these films\, based on porous graphene\, and their impl
 ementation in membranes for postcombustion capture. I will discuss highly-
 effective methods to produce these films\, and our recent efforts to scale
 -up membranes for kilogram scale capture. I will discuss engineering chall
 enges for bringing this technology to market. Finally\, I will present EPF
 L Solutions4Sustainability project geared towards tackling carbon capture 
 at the rate of one ton per day. \n\n\n\n \n\n\n\n
