spherical palladium catalyst

Product Overview

Description

Liming Research & Design Institute of Chemical Industry Co., Ltd. successfully developed sylindric palladium catalyst (APC-T-1) and spherical palladium catalyst (APC-Q-1). Currently, the Company has spherical palladium catalyst production plant of 200 tons / year, production scale of which is in the lead in China. The produced spherical palladium catalyst has been widely used in over 60 plants at home and abroad, especially most of the large-scale hydrogen peroxide plants basically adopted Liming Company catalyst. The technology using aluminum powder as raw material and oil column for shaping was first used by Liming to produce spherical palladium catalyst,belonging to pioneering in China.The comprehensive performance of the catalyst is stable , stands in front ranks among the similar products in China. The spherical palladium catalyst owned higher domestic market share and has successfully been exported to the international market. This catslyst has won the second grade scientific and technological progress prize of the former State Petrochemical Bureau, the second grade prize for outstanding new product and new technology of Henan Province, and the honorary titles of Henan Province High and New Technology Product and Henan Province Excellent Quality Product.

 

In 2014, Liming Research & Design Institute of Chemical Industry Co., Ltd. developed a new type of highly efficient palladium catalyst, increasing production capacity by more than 30%.

 

Product characteristics:
1.Large pore volume,high activity,good stability,long application life
The product which uses oil column forming method has good pore structure and advantages like large pore volume,large specific surface,concentrated pore diameter and high strength. The activity is 20-40% higher than other catalysts. It is difficult to de-palladium and has good stability,long application life(generally more than five years) because of the high activity and stable precious metal components.
2. hydrothermal stability
Since the carrier fabrication process is oil column forming method which relies on the oil surface tension one-time molding without external forces like extrusion and rolling, the structural and hydrothermal stability is high.
3. Stable batch quality,high finished product yield,few impurity
The direct material of oil column forming method is liquid gelatin, and the spherical molding relies on the oil surface tension and specific gravity which is easy to operate and makes the catalyst uniform in size; the product use high specification raw materials to guarantee the few impurity.
Product Usage:
It is widely used in catalytic hydrogenation,absorptive removal fields of chemical industry,medical industry,environmental protection, such as anthraquinone hydrogenation in the hydrogen peroxide production,desulfurization,olefin de-acetylene,gas de-oxy purification.
