ASTM D4530 Automatic Micro Carbon Residue Tester
ASTM D4530 Automatic Micro Carbon Residue Tester
MT-CR211
The Automatic Micro Carbon Residue Tester is designed for determining the carbon residue content of petroleum products after evaporation and thermal decomposition under controlled conditions. The instrument is manufactured according to GB/T 17144 – Test Method for Carbon Residue of Petroleum Products (Micro Method) and complies with ASTM D4530 and ISO 10370 standards.
Introduction
Carbon residue is an important parameter used to evaluate the coking tendency of petroleum products. It indicates the amount of carbonaceous residue remaining after a petroleum sample undergoes controlled heating and pyrolysis. This parameter is widely used for assessing the quality of fuel oils, lubricating oils, and heavy petroleum fractions.
Compared with the traditional Conradson carbon residue method (GB/T 268), the micro carbon residue method uses smaller sample quantities and provides faster, more efficient testing. The results obtained using this instrument are consistent with those obtained using the Conradson method.
The Carbon Residue Tester integrates microprocessor temperature control, automatic nitrogen flow regulation, real-time test monitoring, and data storage, ensuring accurate and repeatable testing results for petroleum laboratories.
The instrument is widely used in petroleum refineries, petrochemical plants, metallurgical industries, research institutes, and universities.
