CRAIC Technologies introduces the CoalPro II, a new system that measures vitrinite reflectance and quickly determines the thermal maturity of coal, kerogens and petroleum source rock.
Designed to perform optical analysis of vitrinite and other macerals commonly found in coal, kerogen and source rock, the CoalPro II determines the energy grade of potential energy sources rapidly and accurately.
Optical reflectance of microscopic amounts of vitrinite is one of the most effective ways of grading the energy content of coal and petroleum source rock.
Vitrinite is a maceral and comprised of various polymers, cellulose and lignin. Measuring the amount of light reflected by vitrinite macerals is a key test to determine the thermal maturity and therefore, the energy content of coal, kerogen and petroleum source rock.
The process is also ideal for assessing the suitability of coal blends for steel production.
Standardised by a number of international bodies including ISO and ASTM, the procedure requires the use of a microscope photometer such as the CoalPro II to measure the intensity of light reflected from a microscopic sampling area.
CoalPro II microscope photometers measure the amount of light reflected from samples of the coal blend at hundreds of points after which a statistical analysis is done by the computer.
Based on the results of the statistical analysis, the amount of vitrinite in the sample, its thermal maturity and its energy content are determined.
Since hundreds of measurements are needed to be done on each sample, the otherwise time-consuming process has been completely automated by the CoalPro II microscope photometers, enabling laboratories to improve throughput and accuracy.
In addition to measuring vitrinite reflectance of coal, the CoalPro II can also be used to measure the reflectance of other macerals and work with materials such as kerogen and petroleum source rock.
The CoalPro II can also measure the fluorescence from these materials.
