Question
Answer the following about carbon scrubbing, or methods of removing carbon dioxide from exhaust gas, for 10 points each.
[10e] Carbonate looping involves minerals reacting with CO2 in the air to form stable materials like this sedimentary rock, which is made up of calcium carbonate.
ANSWER: limestone
[10m] Most solid-state scrubbers involve this process, in which the CO2 attaches itself to the surface of the scrubber material. It is contrasted with a [emphasize] different process in which a gas simply inhabits the volume of the material.
ANSWER: adsorption [or adsorbing; reject “absorption”]
[10h] These highly porous materials originally developed by Omar Yaghi are common scrubbing adsorbents. In these materials, carbon-based struts form a network between atoms like zirconium or cadmium.
ANSWER: metal-organic frameworks [or MOFs; prompt on zeolites]
