Installation for determination of yield of semi-coke products (accelerated method)

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
