Product Description
The Denti-Ball-Shaped Catalysts were developed by Beijing Gaoxin Lihua Catalytic Materials Limited Comany. These novel catalysts are specifically designed for hydrogenation processing of various fuels and feedstocks of other processing units, and have commercial applications in oil refineries of China since 2002.
Each Denti-Ball-Shaped Catalyst is spherical with concavities on its surface, and has a much larger external surface area than existing ball-, cylinder- and tri-lobular-shaped catalysts. When packed in a reactor, the Denti-Ball-Shaped Catalyst increases the void volume in the catalyst bed, thus reducing bed catalyst pressure drop. This increased void volume is attributable to the presence of countless tiny grooves in the catalyst particles themselves, in addition to the spaces between particles, which together form a complex network. The bed density of the Denti-Ball-Shaped Catalyst is more uniform than that of the cylinder or tri-lobular shaped catalystd thanks to the more uniform diameters of the Denti-Ball-Shaped Catalyst particles. This structural advantage helps avoid the phenomena of bridging and overly-dense packing often observed in the cylinder or tri-lobular shaped catalysts. Due to its superior structural features, the Denti-Ball-Shaped Catalysts are an excellent choice with respect to heat removal, mass transfer, and overall efficiency.
The Denti-Ball-Shaped Catalyst are particularly suitable for hydrogenation processes in which the pressure drop of the catalyst bed is a big concern. Recently, Beijing Gaoxin Lihua Catalytic Limited Company has developed several types of Denti-Ball-Shaped Catalysts, such as catalysts for the second stage hydrotreating process of pyrolysis gasoline, catalysts for hydrofining coker naphtha, and catalysts for upgrading the fuel with poor ignition quality. These catalysts have been used commercially. Application results indicate that the pressure drop observed in Denti-Ball-Shaped Catalysts for the second stage hydrotreating of pyrolysis gasoline is only one third of that observed in tri-lobular shaped catalysts.
Beijing Gaoxin Lihua Catalytic Materials Limited Company (former Beijing Gaoxin Lihua Chemical Industry Limited Company, hereafter referred to as Gaoxin Lihua) is an important high-tech company in Beijing Opto-Mechatronics Industrial Park (OIP). Gaoxin Lihua is dedicated to developing and manufacturing quality catalysts for oil-refining and petrochemical processes, advanced plastic processing additives for plastic industry, and rhodium catalysts for hydroformylation reactions in chemical industry. Gaoxin Lihua, armed with advanced technologies and equipment, possesses the following production units: One set of solid catalyst production line with a capacity of 1500t/a, one set of denti-ball shaped and trilobal shaped support production line with a capacity of 1000t/a, one set of advanced plastic additive processing line with a capacity of 1000t/a, and one unit for recovering rhodium from spent catalysts.
The scientists and technologists of Gaoxin Lihua dedicate themselves to the Development and Research of new products and technologies. The major products of Gaoxin Lihua include hydro(re)fining catalysts, hydrocracking catalysts, hydroprocessing guard catalysts, advanced plastic composite additives, PP nucleating agent, etc. These products have been and are being used by many large oil refineries and plastic plants, and the feedback has been really good. The performance of these products has achieved the top level in domestic markets, and some related manufacturing techniques, such as those applied to denti-ball shaped catalyst support, are unique and innovative.
