My company to develop synthetic hydrofining and hydrocracking catalyst (JEHT - 41,42,43) is mainly used in the coal tar catalytic cracking residue and the harmonic components of the gasoline and diesel, mainly in clover (applicable to fixed bed) or ball (applicable to ebullated bed residue cracking) composite aluminum oxide as a carrier, with molybdenum, tungsten, cobalt, nickel and other metal components and additives, entrance is big, large specific surface area, and the compressive strength, high wear resistance strength. Among them, jeht-41 is a purified hydrogenation catalyst. The jeht-42 catalyst is a transition metal-supported catalyst mainly used for cracking reaction. Eht-43 is modified by new structure auxiliaries and new preparation process, with higher dispersity and mechanical strength of active components. It is suitable for cracking of inferior coal tar and higher oil yield. The catalyst in the coal tar, anthracene oil hydrogenation catalysis showed good catalytic performance and stability, in the reaction temperature 330-360 ℃, pressure of 12.5 to 15.5 MPa operating conditions, coal tar oil yield reached above 93%, the service life of the catalyst can reach more than 3 years.

This series of catalysts have been in the leading position of similar products at home and abroad.
