Fig. 3: PDH performance.
From: Reaction-induced dynamic evolution of PtIn/SiO2 catalyst for propane dehydrogenation
a PDH performance of PtIn1.0/SiO2 under different propane partial pressures at 550 °C. b PDH performance of PtIn1.0/SiO2 as a function of nominal Pt-to-In mass ratios. c PDH performance of PtIn1.0/SiO2 at different temperatures. d PDH stability test of PtIn1.0/SiO2, Pt/SiO2 and Pt3In NPs/SiO2. Reaction condition: atmospheric pressure, WHSV = 39 h−1, 550 °C, C3H8/H2 = 2/1. The inset shows the bottom of the quartz tube before and after the PDH reaction. e C3H6 productivity versus C3H6 selectivity for the Pt-based catalysts described in this work and literature. The catalysts included here are only the best-performing ones from the articles considered.
