A hydrogenation catalyst for coal tar, a method of hydrogenation of coal tar with use of such catalyst, and a method of producing super needle coke from the hydrogenation product of coal tar
A hydrogenation catalyst for coal tar, a method of hydrogenation of coal tar with use of such catalyst, and a method of producing super needle coke from the hydrogenation product of coal tar
A catalyst used for hydrogen treatment of coal tar is characterized in that about 10 to 30 weight percent of Mo oxides as first catalyst component and about 1 to 6 weight percent of Ni and/or Co as second catalyst component, both related to the total catalyst weight, are supported on a porous inorganic substrate consisting essentially of alumina or silica alumina, and in that the mean pore size is about 8 to 18 nm, the pore size distribution is such that 1and the total pore surface is higher than about 100 m2/g. The invention includes a method of hydrogen treatment with use of the catalyst, and a method of producing a super needle coke suitable for the preparation of the graphite electrode, which consists in subjecting the hydrogenated oil resulting from such hydrogen treatment to delayed coking.
