Process for the production of hollow carbon fiber membranes

摘要

A process for manufacturing a bundle of hollow carbon membranes, comprises the steps of: a. providing a bundle of hollow cellulose fibers; b. removing substantially all the absorbed water from the said fibers; c. heating the fibers to a range of temperatures where it pyrolyzes; d. supplying to the said fibers, during at least part of the heating thereof and after the water has been removed, a catalytically effective amount of a gaseous catalyst selected from among Lewis acids, and ionic salts that are at least partially volatile at the pyrolysis temperature range.
