ASTM D2318 - Standard Test Method for
This test method covers the determination of the quinoline-insoluble matter (QI) in tar and pitch. Since this test method is empirical, strict adherence to all details of the procedure is necessary. The values stated in SI units are to be regarded as standard. No other units of
Impregnating-Grade Coal Tar Pitch | National
The impregnating-grade coal tar pitch is a special type of coal tar pitch, which has a low content (0-3 %) of quinoline insolubles (QI), besides having lower values of softening point (SP), toluene insolubles (TI), coking yield and specific gravity (SG), compared to those of the binder-grade coal tar pitch. It is used in large quantities to densify graphite electrodes, employed in steel and
Coal Tar Pitch – IspatGuruProduction of coal tar pitch. Coal tar pitch is currently produced from coal tar, which is a byproduct of high temperature coking of coal in the manufacture of metallurgical coke. The tar predominantly contains a mixture of bi- and poly-condensed aromatic hydrocarbons and also compounds with heteroatoms in rings (predominantly nitrogen bases from the quinoline and acridine series, 1 % to 2 % Coal Tar for Psoriasis - Verywell HealthCoal tar is a byproduct of coal processing that has been used for more than a century to treat skin problems. Today, it is considered an effective, safe, and inexpensive topical treatment for plaque psoriasis.Available in different strengths and formulations, coal tar is included on the World Health Organization (WHO)'s List of Essential Medicines.

coal tar pitch production processCoal tar availability in the US has therefore improved as its domestic production has exceeded the demand from the aluminium, graphite and other coal tar pitch end-use sectors. CRU expects the volume of coal tar available in the US to rise to 210,000t in 2016, up by 61.5% year-on-year. Canada, on the other hand, is short on coal tar as its domestic production is unable to meet the demand from

Metallurgical Coal and Coke Testing - SGS
coal blends will perform in by-product coke ovens in terms of ease of pushing of the coke mass from the oven, coking pressure, and resultant coke quality. SOLE HEATED OVEN (SHO) Tests done in the sole heated oven evaluate the contraction or expansion tendencies of coals or coal blends when heated under controlled conditions.
