Abstract Content
Carbon occurs as a variety of allotropes. There are two crystalline forms diamond and graphite and a number of amorphous (non-crystalline) forms, such as charcoal, coke, and carbon black. The most common use of carbon black is as a pigment and reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Coke is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Elemental analysis is fundamental for the characterization of these type of materials to ascertain the quality needed for better engine performance and to help with the identification of vehicle exhaust constituents that are harmful and hazardous to the environment. The FLASH 2000 CHNS/O Analyzer permits the fast quantitative determination of the elements in petrochemical materials. The system, which is based on the dynamic combustion of the sample, provides automatic and simultaneous CHNS determination in a single analysis run and the Oxygen determination by pyrolysis in a second run. To perform total Sulfur determination at trace levels the Analyzer has been coupled with the flame photometric detector (FPD). This paper presents CHNS/O data of different coal, coke, graphite and carbon black samples analyzed several times to show the reproducibility obtained with the system.
