Petroleum product residual carbon tester (Conics method)

The petroleum product residual carbon tester is a specialized equipment used to determine the mass percentage of charred black carbonaceous residue left after thermal evaporation, cracking, and condensation of petroleum products (such as lubricating oil, heavy fuel oil, crude oil, asphalt, etc.) under non air conditions.

The percentage value measured is called the 'residual carbon value'. It does not represent the inherent carbon content in the oil, but reflects its ability to generate carbon deposits after thermal conversion under specific harsh conditions.

Conradson Carbon Residue (CCR)

Applicable samples: relatively light oils such as lubricating oil and heavy fuel oil (but gradually replaced by the Langmuir method).

Instruments and principles:

Ceramic crucible: used to hold samples.

Iron crucible: As an outer crucible, sand is laid on the bottom for uniform heating and air isolation.

Flame blocking body (metal circular cover): Ensure uniform heat distribution.

Triangle frame and gas lamp: provide standardized strong heat source.

Process: Weigh the sample → Strong preheating period (10 ± 2 minutes) → Intense combustion period → Transfer to a high-temperature furnace (500-550 ° C) for calcination → Cooling and weighing.

Characteristics: Classic method, but cumbersome operation steps, high requirements for heating intensity control, and poor repeatability.

Mainly used to determine the amount of residual carbon left after evaporation and pyrolysis of petroleum products, in order to provide an indicator of the relative coking tendency of petroleum products?. Is this method suitable for petroleum products that are easily partially decomposed and relatively non-volatile during atmospheric distillation?. The working principle of the Kang's method is to place a fixed weight sample into a crucible and heat it up, so that the temperature of the sample in the inner crucible reaches about 600 ℃. Under the condition that air cannot enter, the different heating levels of the preheating period, combustion period, and strong heating period are controlled, so that the sample evaporates and decomposes to form residual carbon?.

This instrument is designed and manufactured in accordance with the requirements of the People's Republic of China standard GB/T 268 "Determination of Residual Carbon in Petroleum Products (Kjeldahl Method)", and is suitable for measuring the amount of residual carbon left after evaporation and pyrolysis of petroleum products to provide an indicator of the relative coking tendency of petroleum products.
