Title:

ACTIVE CARBON CARRIER, CATALYST-CARRYING ACTIVE CARBONS, AND METHOD OF PRODUCING THEM

Document Type and Number:

Japanese Patent JP2004025023

Kind Code:

A

Abstract:

To provide an active carbon carrier which, in order to improve the reaction efficiency of hydrogenation and dehydrogenation reactions by a catalyst, has a large specific area and is excellent in thermal conductivity and diffucibility of hydrogen gas, a raw material, and a product and catalyst-carrying active carbon in which a metal catalyst is carried on the active carbon carrier.

The active carbon carrier of a fibrous active carbon fabric is obtained by knitting a fibrous polymer, then carbonizing/activating the fibrous polymer and characterized in that the O/C ratio on the surface by an X-ray photoelectron spectroscopy method (XPS) is at least 10%, gas-permeability is at least 200 cm3/cm2s, a toluene adsorption capacity is at least 25 g/m2, and a specific surface area by a BET adsorption istherm method is 500-3,000 m2/g.
