This catalyst demonstrated outstanding catalytic performance in PDH. At a weight hourly space velocity (WHSV) of 354 h⁻¹, it achieved propylene formation rates of 256 and 390 mol C₃H₆ g ...

Take propylene, which has seen some of the most dramatic increases. Small, specialized plants that turn gas into the material — known as propane dehydrogenation, or PDH, units — have proliferated.
