   Platinum can be used with natural gas, propane and butane. It generates a surface temperature of 300–550 °C, lower than the 760 °C ignition point. [6] Pt heaters are the most common type. [7] Palladium can be used with hydrogen gas. Pd-coated carbon was used in 2010 for a prototype heater built by the Sandia National Laboratory. [8]

   Blended from pure, dry propane (refrigerant designator R-290) and isobutane (R-600a) the blend "R-290a" has negligible ozone depletion potential, very low global warming potential and can serve as a functional replacement for R-12, R-22, R-134a and other chlorofluorocarbon or hydrofluorocarbon refrigerants in conventional stationary ...

6. Propane refrigeration - Wikipedia

   en.wikipedia.org/wiki/Propane_refrigeration

   Only propane produced specifically for use in refrigeration systems – with a purity of at least 98.5% and moisture content below 10ppm (by weight) – should be used. [ 1 ] With a global warming potential (GWP) of 0.072 [ 2 ] and an ozone depletion potential (ODP) of 0, R-290 is of very little threat to the environment.
