Petroleum Products Carbon Residue Tester (Micromethod)

The Micro Carbon Residual Tester is a precision instrument used to determine the residual carbon content of petroleum products, lubricants, biofuels, etc. after pyrolysis under certain high temperature conditions. It quantifies the coking tendency of samples by simulating the pyrolysis process in anaerobic or low oxygen environments.

Petroleum Products Carbon Residue Tester-5

Carbon Residue Tester (Micromethod)


The carbon residue tester is a professional analytical instrument designed based on the ASTM D4530 standard (Determination of Trace Residual Carbon in Petroleum Products). It is mainly used to accurately determine the amount of carbonaceous residue remaining in petroleum products (such as residual fuel oil, lubricating oil, crude oil, heavy distillate oil, etc.) after heating under high temperature and inert gas atmosphere, in order to evaluate the thermal stability and coking tendency of the sample. Its core advantages lie in low sample usage, high degree of automation, and high detection accuracy, making it suitable for rapid analysis and quality control of heavy petroleum products in modern laboratories.

Principle:

The Carton Residue Tester simulates an anaerobic high-temperature cracking environment, places a certain amount of sample in a specially designed crucible, and heats it under inert gas protection (to avoid interference from oxidation reactions) according to the standard heating procedure. After evaporation and cracking, the sample ultimately forms a stable carbonaceous residue. After cooling, the instrument automatically weighs the residual mass and calculates the residual carbon value (the percentage of residual carbon mass to the original sample mass) to quantify the coking potential of the sample at high temperatures.


Main technical specifications:

Temperature of coke chamber

500℃

Ambient temperature

15℃~35℃

Power supply

AC(220±10%)V, 50Hz

NW

18.5kg

Relative humidity

≤85%

Power consumption

≤1400W

Dimension

500mm×280mm×550mm

Features:

  1. Micro sampling: Only a small amount of sample is required, suitable for precious samples or small batch testing (compared to the traditional Koch method which requires about 100 grams of sample).

  2. Automated operation: From heating program control to data processing, the entire process is automated, reducing human intervention and improving efficiency and repeatability.

  3. High precision detection: using crucible and inert gas protection to avoid impurity interference, the measurement accuracy of residual carbon value can reach ± 0.05% (mass fraction).

  4. Quick analysis: A single test takes about 90-120 minutes, which is more efficient than traditional methods.
