Pearson Coal Petrography
Fingerprinting your coals, cokes, and carbons
Pearson Coal Petrography provides microscopic evaluations of coking coals, steam coals, metallurgical cokes, and carbons, from state-of-the-art laboratories located in Canada, the United States, and Australia.
Measurement of mean maximum reflectances, measured in oil of polished surfaces of vitrinite and other macerals present in coal. Using International Standards ASTM D2798, ISO7404-5
Measurement of the maceral composition of coal, using a point count method to determine the volume percent of organic components and mineral matter in coal; as described in International Standards ASTM D2799 and ISO7404-3
Developed in-house digital whole coal reflectance measurements of coals to get reflectance profiles that are measured to 0.01% reflectance, quickly and accurately used to compare trains, cargoes, or core samples
Bireflectance image analysis aids in the determination of coke components based on optical properties. Measurement based and currently being developed into an ASTM standard.
Oxidized coals specifically due to weathering is often difficult to ascertain. Using a selective dye we can demonstrate weathering clearly, and definitively
Over the years our research has been published in a variety of journals and conference proceedings. Need help finding an old paper or reference of ours, contact us here.
Our blend analysis software is the most sophisticated that we are aware of. Using numerical models of component coals, blend proportions can be determined and modeled to get the best of your coking coal blends.
Trying to understand the fluidity fluctuations in your coals, or perhaps you have a research project that requires fluorescence images of your coals. We can help.
Testing swelling and plastic properties of coals are critical for understanding coking performance of a coal.
Over the past week, we have been very busy moving our laboratory and equipment to newer facility in Downers Grove. Right next to the Belmont Met
This year the Association for Iron And Steel Technology main event is being held in Pittsburgh, Pennsylvannia, 6-9th of May. Dave Pearson wil
Until recently, few options were available to untangle the optical secrets of metallurgical coke, which is characterized by a wide range of refl
Our lab in Catlettsburg, Kentucky has out grown its space. We are happy to announce that we are moving to a larger South Charleston facility.
