Commercial Progress on Turquoise Hydrogen

Producing hydrogen via methane pyrolysis – termed ‘turquoise hydrogen’ – has thus far received less attention than ‘blue’ and ‘green’ H2, but it may offer advantages over both While the vast majority of current hydrogen production occurs by steam reforming…

Facts At Your Fingertips: Wet and Dry Milling

Milling is a common technique for controlling particle-size distribution (PSD) in solid products through size reduction and surface modification. Broadly, mills can be categorized as wet or dry mills, and these two categories are each further subdivided by how comminution…
