Editing Adsorption (section)

==Carbon capture and storage==
Typical adsorbents proposed for [[carbon capture and storage]] are [[zeolite]]s and [[Metal-organic framework|MOFs]].<ref>{{Cite book|title=Introduction to carbon capture and sequestration|last1=Berend|first1=Smit|last2=Reimer|first2=Jeffery A|last3=Oldenburg|first3=Curtis M|last4=Bourg|first4=Ian C|publisher=Imperial College Press|year=2014|isbn=9781306496834 }}</ref> The customization of adsorbents makes them a potentially attractive alternative to absorption. Because adsorbents can be regenerated by temperature or pressure swing, this step can be less energy intensive than [[Absorption (chemistry)|absorption]] regeneration methods.<ref>{{cite journal |last1=D'Alessandro |first1=Deanna M. |last2=Smit |first2=Berend |last3=Long |first3=Jeffrey R. |title=Carbon Dioxide Capture: Prospects for New Materials |journal=Angewandte Chemie International Edition |date=16 August 2010 |volume=49 |issue=35 |pages=6058–6082 |doi=10.1002/anie.201000431 |pmid=20652916 |url=http://infoscience.epfl.ch/record/200571 }}</ref> Major problems that are present with adsorption cost in carbon capture are: regenerating the adsorbent, mass ratio, solvent/MOF, cost of adsorbent, production of the adsorbent, lifetime of adsorbent.<ref>{{Cite journal|last1=Sathre|first1=Roger|last2=Masanet|first2=Eric|date=2013-03-18|title=Prospective life-cycle modeling of a carbon capture and storage system using metal–organic frameworks for CO2 capture|journal=RSC Advances |volume=3|issue=15|pages=4964|doi=10.1039/C3RA40265G|bibcode=2013RSCAd...3.4964S |issn=2046-2069}}</ref>

In [[sorption enhanced water gas shift]] (SEWGS) technology a pre-combustion carbon capture process, based on solid adsorption, is combined with the [[Water-gas shift reaction|water gas shift reaction]] (WGS) in order to produce a high pressure hydrogen stream.<ref>{{cite journal |last1=Jansen |first1=Daniel |last2=van Selow |first2=Edward |last3=Cobden |first3=Paul |last4=Manzolini |first4=Giampaolo |last5=Macchi |first5=Ennio |last6=Gazzani |first6=Matteo |last7=Blom |first7=Richard |last8=Henriksen |first8=Partow Pakdel |last9=Beavis |first9=Rich |last10=Wright |first10=Andrew |title=SEWGS Technology is Now Ready for Scale-up! |journal=Energy Procedia |date=2013 |volume=37 |pages=2265–2273 |doi=10.1016/j.egypro.2013.06.107 |doi-access=free |bibcode=2013EnPro..37.2265J }}</ref> The CO<sub>2</sub> stream produced can be stored or used for other industrial processes.<ref>{{cite journal |last1=(Eric) van Dijk |first1=H.
