Single- and double- roll crushers are used for the initial reduction from run- of-mine to a nominal 6- to 8-inch size. A secondary crusher, often of the hammer-mill type, reduces it to less than 2 inches for shipping. In the central and eastern coal regions, all coal is similarly crushed and sized before shipping or processing.

CO2 thickeners have the potential to be a game changer for enhanced oil recovery, carbon capture utilization and storage, and hydraulic fracturing. Thickener design is challenging due to polymers' low solubility in supercritical CO2 (scCO2) and the difficulty of substantially increasing the viscosity of CO2. In this contribution, we present a framework to design CO2 soluble thickeners ...
