WebAug 1, 2024 · Samples were pretreated at different temperatures: mild activation at 773 K (treatment 1) and high-temperature activation at 823, 873, 973, and 1073 K (treatment 2). The catalysts showed similar catalytic propane reaction rates within the experimental error. Propane is a popular choice for barbecues and portable stoves because the low boiling point of −42 °C (−44 °F) makes it vaporize as soon as it is released from its pressurized container. Therefore, no carburetor or other vaporizing device is required; a simple metering nozzle suffices. Blends of pure, dry "isopropane" (R-290a) (isobutane/propane mixtures) and iso…
