โฆ Synopsis
Exploratory runs have shown it to be possible to produce a sieve for the separation of O1 from Ar by depositing carbon from propylene in or over an activated carbon (AC) previously impregnated with Ni. It is thought that preferential cracking of propylene at the Ni sites within the pores of the AC particles and/or at the particle exterior surface introduces apertures of size O.S4-0.S7 nm-the size req&ed for this sepal-at&n.

Modification of the pore size of several types of carbon adsorbents by chemical vapour deposition of carbon from benzene at 1000 K was examined. The carbons included commercial molecular sieve carbon (MSC), pitch based active carbon fiber (ACF), super and commercial active carbon (S-AC, AC). Greatly
The effect of copper metal supported on activated carbon on the catalytic reduction of NO has been studied as a short reaction process. It was observed that the adsorption properties of the activated carbons plated with copper metal slightly decrease with an increasing in the plating time or amount
Activated carbon cloth is impregnated by dipping in solutions of cobalt acetate or nickel acetate to give a range of loadings. Prepared cloths were used to form filter beds, 20 layers thick, which were exposed to hydrogen cyanide (HCN)-laden air. Challenge concentration was 2 mg L-' HCN in air at 80
