For more than 30 years, Haldor Topsoe A/S has been involved in the development and production of hydrotreating catalysts. HYDROPROCESSING CATALYSTS AND TECHNOLOGIESBased on the fundamental work and understanding of the reaction pattern on the atomic level, Topsoe is able to supply a whole range of hydroprocessing catalysts and technologies. For the petroleum industry, Topsoe has developed a series of hydroprocessing catalysts, denominated TK-series. These catalysts are used for reduction of sulphur, nitrogen, metals and aromatics in petroleum fractions. Topsoe's strong R&D commitment ensures a continual improvement of the TK-catalyst portfolio, enabling refiners to competitively supply fuels which meet increasingly severe specifications. As grading material, Topsoe catalysts are available as rings. They have proved efficiently in delaying pressure drop build-up, which is a frequent problem in many hydroprocessing units. The most important hydroprocessing catalysts and services Topsoe offers to the petroleum industry cover the following applications:
ULTRA LOW SULPHUR DIESEL PRODUCTIONOver the last couple of years, Topsoe has spent considerable efforts in establishing the reactivity of sulphur components and investigating the catalysts and operating conditions to reduce the sulphur content of diesel to less than 10ppm, thus helping refiners to comply with new regulations:
New high activity catalysts are a prerequisite to meet future, more stringent specifications for diesel fuel. TK-575 BRIM and TK-576 BRIM are the latest of the new generation catalysts based on Topsoe BRIM Technology. The unique combination of improved Type II and brim reaction sites makes these catalysts ideal for ultra low sulphur diesel applications. HYDROCRACKINGWithin the last decade, Topsoe has also had an extensive program for the development of hydrocracking catalysts and technology and today, Topsoe's hydrocracking technology comprises:
The Topsoe hydrocracking process uses a clever combination of process conditions and superior hydrotreating and hydrocracking catalysts to meet the required conversion as well as required product quality specifications from every unique hydrocracker feed stock blend. It also features an industry leader catalyst, graded-bed design for reactor pressure-drop control as well as state-of-the-art reactor internals specifically designed for hydrocracking service. TOPSOE HIGH PERFORMANCE REACTOR INTERNALSEven the best catalysts can only provide optimum performance in reactors of proper design. At an early stage, Topsoe recognised the importance of having uniform flow distribution in hydroprocessing reactors. Topsoe's extensive research and development into new and more efficient liquid distributor trays and quench mixing assemblies has resulted in the technical and commercial success of several new and innovative solutions for hydroprocessing reactors. In some commercial applications, the installation of Topsoe reactor internals more than doubled the catalyst activity and cycle length. Today more than 150 Topsoe High Performance Reactor Internals have been sold worldwide for a wide range of hydroprocessing services.
