Carbon Residue Tester

Carbon residue testing solutions for petroleum, fuel, and industrial oils.
Carbon residue testers are used to determine the amount of carbonaceous residue remaining after evaporation and pyrolysis of petroleum products, fuels, and industrial oils. Carbon residue testing is essential for evaluating thermal stability, deposit-forming tendency, and fuel quality.

Carbon Residue Test Methods:

Conradson Carbon Residue (CCR)
A traditional method for determining carbon residue in petroleum products.
Micro Carbon Residue (MCR)
A modern method using smaller sample volumes and improved repeatability.
Ramsbottom Carbon Residue (RCR)
Commonly used for evaluating fuel oils and petroleum fractions.

Standards for Carbon Residue Testing

ASTM D189 – Conradson Carbon Residue
ASTM D4530 – Micro Carbon Residue
ASTM D524 – Ramsbottom Carbon Residue ISO 4262 – Carbon Residue of Petroleum Products

Carbon Residue Testing Solutions

Carbon residue testing measures the tendency of petroleum products and industrial oils to form carbon deposits when subjected to high temperatures in the absence of air.

Excessive carbon residue can indicate poor thermal stability and may lead to deposits in engines, burners, and industrial equipment. Carbon residue testing supports quality control, refining processes, and product specification compliance for fuels and industrial oils.

Carbon residue testers provide controlled heating conditions and consistent test environments to ensure accurate and repeatable results.

Applications of Carbon Residue Tester

Our carbon residue testers are widely used in:

· Carbon residue determination in petroleum products
· Fuel quality testing for diesel, fuel oils, and residual fuels
· Evaluation of thermal stability of industrial oils
· Refinery process control and product classification
· Petrochemical and third-party laboratory testing

Key Carbon Residue Testing Parameters

Measured as a percentage of the original sample mass.

· Heating Conditions
Controlled temperature and time to ensure consistent pyrolysis.

· Sample Size
Varies depending on the selected test method.

· Result Repeatability
Ensures reliable comparison for quality control and specification testing.
