Summary:
Iowa State University researchers have developed a propane dehydrogenation method to transform shale gas efficiently to propylene, which allows a new route to the second most abundant polymer, polypropylene. This is the first example of using carbide nanostructures for the catalytic dehydrogenation of propane, propylene selectivity was shown to be greater than literature state of the art catalysts, as high as 95%. Conversion rate is consistent with the best commercial catalysts.

Development Stage:
Description:
Shale gas contains large amounts of propane gas. As dehydrogenation of propane into propylene represents an enormous market opportunity, propane dehydrogenation catalysts have been highly valued and extensively researched. Iowa State University researchers have demonstrated that carbide nanostructures have state of art selectivity and conversion percentage compared to the literature analogues for propane dehydrogenation. Their results have shown that the metal-carbide composite alloy catalysts significantly increases propylene selectivity (98%) of propane dehydrogenation reaction compared to pure Pt catalysts (85%) at similar conversion. ISURF #4665 may represent the best available catalyst and most selective catalyst for propane dehydrogenation.

Advantage:
• Significantly higher selectivity
• Low by-product formation
• Much reduced cost compared with current commercial catalysts
• Consistent conversion rate with the best commercial catalysts

Application:
Carbide catalysts will be widely used for propane dehydrogenation.
