Installation for determination of yield of semi-coke

Installation for determining the yield of semi-coking products (accelerated method) is designed for testing in accordance with GOST 3168-93 (ISO 647-74) "Solid mineral fuel. mineral. Methods for determining the yield of semi-coking products" and allows to determine in brown and hard coals of tar, pyrogenetic water, semicoke and gas yields at accelerated semicoking and consists in heating 1 g of an analytical sample of coal in a glass retort to 550 ° C.

glass retort up to 550 °? without access to air. The indicator of semi-coking tar yield is the basis for classification of lignite coals as a raw material for low-temperature processing.

The unit is widely used in petrochemical industry. The unit consists of electric tube furnace, electric split tube furnace, a retort made of heat-resistant glass, a resin receiver and a water receiver connected by slits, thermocouple and analytical scales.
