Introduction

Carbon residue is an important parameter used to evaluate the coking tendency of petroleum products during thermal decomposition. The test measures the amount of carbonaceous residue remaining after evaporation and pyrolysis of the sample under specified conditions.

In this method, the sample is heated using a gas flame heating system in a set of nested crucibles. The volatile components are evaporated, and the remaining material undergoes thermal decomposition to form carbon residue. The final residue is used to assess the tendency of fuels and oils to form deposits during high-temperature operation.

This Conradson Carbon Residue Apparatus features a simple structure, complete accessory configuration, and easy operation, making it suitable for laboratories that require a traditional and cost-effective carbon residue testing solution.

It is widely used in petroleum laboratories, fuel testing facilities, research institutes, and educational institutions.
