Enhancement of N_2 Formation from the Nitrogen in Carbon and Coal by Calcium

摘要

The effects of Ca catalysts on nitrogen release during heat treatment of polyacrylonitrile-derived carbon and pyrolysis of low rank coals have been studied with a fixed bed quartz reactor in a stream of high purity He. In the temperature-programmed treatment at 10deg.C/min of the carbon with 3 wt /100 Ca, the Ca promotes N_2 formation at 850-1000deg.C and the catalytic effect is larger at a higher temperature.
