Osaka Gas Chemicals manufactures a variety of activated carbons. High-performance products were specially designed for use as catalyst / catalyst support for chemical synthesis of chemicals, medicines, aglicultural chemicals, pesticides etc. Contact us for sample requests and information.

Benefits of using activated carbon as a catalyst support

触媒担体活性炭への金属吸着機構

The biggest benefit of using activated carbon as a precious metal supported catalyst carrier is that it can easily separate and collect precious metals such as iridium ( Ir ) that it carries.
Easy recovery of iridium compared with other carriers such as zeolites, silica or alumina.
Osaka Gas Chemicals' activated carbons low ash content make them specially performant for iridium recollection.

Pellet charcoal

High purity required for precious metal (eg iridium) support.
Low impuritiy levels will cause less interferences with the catalyst and improve performance. Furthermore, activated carbons are available in different shapes (powders, granules, extrudates). Particle size or microstructure (pore size) can be adapted for each application.

Adjustments of pore size and particle size depending on purposes and applications

The powdered activated carbon "SHIRASAGI FAC - 10" manufactured by Osaka Gas Chemicals has high filtration performance as well as high purity. Granular activated carbon "SHIRASAGI C2c" and "SHIRASAGI C2x" with hardness to withstand long-term use are grade products with improved attrition loss. Outline of activated carbon for catalyst / catalyst support of Osaka Gas Chemicals is summarized in the table below.

  • Osaka Gas Chemical's activated carbon for catalyst / catalyst support are made from wood and coconut shells, and clear the high purity required for catalyst carriers and activated carbons for catalysts.
  • Osaka Gas Chemical's activated carbon for catalyst / catalyst support come in various grades depending on the particle size distribution, attribution loss, and crush strength. For industrial use, there are pellet activated carbon C2x series with uniform particle size and excellent hardness, crushed activated carbon C2 series with an emphasis on cost performance, and powdered activated carbon FAC-10 for fine chemicals.
  • FAC-10 for fine chemicals is a high-spec grade with optimally sized pores for supporting metals in the reaction, providing high efficiency in the separation process. It is also superior in mesoporousness. (A material having mesopores, which is between micropores and macropores, tends to cause a chemical reaction using the inside of the pores.)
