In production and transportation process of coal gas

the coal tar has comparatively severe harmness. In order to study the splitting property of tar

test and research about tar extrication in cogeneration scheme of partial coal gasification by using air have been carried out on a 1 MW CFB heat

electricity

and gas cogeneration testing equipment

to investigate the influence of operation temperature in gasification furnace and of adding lime stone upon the tar splitting. In addition

an oxidation pyrolysis facility of tar has been designed

and test of oxidation pyrolysis for tar being carried out. Result of test shows that the tar content in coal gas has been remarkably reduced along with increasing the temperature of oxidation pyrolysis.
