CATALYTIC HYDROPYROLYSIS OF COKE OVEN TAR FOR PRODUCTION OF LIGHT AROMATIC HYDROCARBON LIQUID

摘要

Using three kinds of catalyst, the hydropyrolysis of tarry materials was investigated. 1). The LAH yields depended on the catalysts and the reaction conditions. Using catalysts in the hydropyrolysis reaction, the LAH yields clearly increased. 2). A Indonesian natural limonite ore showed a high activity for catalytic hydrocracking of the coke oven tar. The maximum LAH yields (benzene 5.47 wt%, toluene 1.09 wt%, naphthalene 7.35 wt% on the basis of carbon content in the tar) was obtained at 773 K in 50% of hydrogen atmosphere. 3). The coke oven tar can be converted to high quality fuel gas with limonite.
