Reduced catalytic carbonaceous char and process for reducing the inherent carbon catalytic reactivity of carbonaceous chars

摘要

A process is provided for reducing the inherent carbon catalytic reactivity of carbonaceous chars. In this process a carbonaceous char is contacted first with a Bronsted acid. The acid-treated char is then heated to temperatures greater than 750° C. By this method the inherent catalytic reactivity of the carbon in the char is reduced effectively and largely irreversibly.
