NIST researchers reported new, high sensitivity compositional characterizations of
RP-1 fuels and new metrological quality property results for density, viscosity, heat capacity, and thermal conductivity with temperatures extending beyond a decomposition limit (near 600 K) and pressures to about 70 MPa.
RP-1 uses Raman inelastic light scattering, which is an identification technology first developed in the 1930s and enhanced in the 1960s with the use of lasers.
The RP-1 reportedly overcomes one of the biggest obstacles in durable-goods recycling - identification of darkly pigmented materials.
The RP-1 may eventually be able to identify materials in a moving stream automatically.
