Abstract

A carbonaceous adsorbent in the form of a shaped body which has been heated to about 400 to 1400.degree. C in an inert atmosphere is composed essentially of a mixture of finely divided carbonaceous material of a grain size below 50 and up to below 100 microns with a binder composed of about 1 to 20% by weight of a natural or synthetic elastomer and about 1 to 15% by weight of a thermoplastic material. The adsorbent is made by subjecting the mixture to a shaping step followed by heating to a temperature of about 400.degree. to 1400.degree. C in an inert atmosphere which step may be followed by an activation of the carbonaceous material.
