The RCRT semi-automatic Ramsbottom carbon residue tester with its gas-free furnace indicates coke-forming properties by determining the amount of carbon residue left after evaporation and pyrolysis of a sample.
RCRT is applicable to relatively nonvolatile petroleum products, which partially decompose on distillation at atmospheric pressure, like diesel fuel, motor oil, gas or crude oil.
ASTM D524, ISO 4262, FTM 791-5002, IP 14
Ambient to +760 °C
This method is used to characterize coke-forming properties based on the amount of carbon residue left after evaporation and pyrolysis of relatively nonvolatile petroleum products like diesel, lubrication oil, gas oil, and crude oil residuum. This value allows users to draw conclusions about sample’s tendencies to form deposits in burner nozzles and in the combustion chamber of fuel-operated systems. In the case of gas oil, crude oil residuum and bright stocks, this value is a manufacturing guidance.
