ISO 647:2017 specifies a method for the determination of the yields of tar, water, gas and coke residue obtained from brown coal and lignite by distillation to a final temperature of 520 °C.
Abstract
Overview
ISO 647:2017 - Brown coals and lignites: Determination of the yields of tar, water, gas and coke residue by low temperature distillation - specifies a laboratory method to quantify tar yield, total water (moisture + decomposition water), gas and coke residue from brown coal and lignite. The test uses a low‑temperature distillation sequence to 520 °C (80 min total heating) with product condensation and gravimetric determination. Results are reported on the and bases and are used as a basis for classification and quality assessment for low temperature carbonization.
