Iowa State University and researchers have developed a process to platinum-tin catalysts for propane dehydrogenation to enhance catalyst lifetime before regeneration up to six-fold.

Propane dehydrogenation is a common method to produce propylene, one of the most important chemical building blocks. Platinum-tin catalysts have been shown to have high selectivity towards propylene with good yield, but suffer from quick deactivation from coking. Iowa State researchers have discovered a treatment method that provides a six-fold increase in catalyst life before coking and deactivation without sacrificing selectivity and yield.

• A six-fold increase in catalyst life before deactivation

• No decrease in yield or selectivity relative to conventionally-treated catalysts

• Cost effective process performed at moderate temperatures and pressures
