THERMAL-TREATMENT OF COATED PRINTING AND WRITING PAPER IN MSW - PYROLYSIS KINETICS

The pyrolysis kinetics of cellulosic coated printing and writing paper , a principal component of municipal solid waste (MSW) in Taiwan, were investigated by thermogravimetric analysis in nitrogen over the tempe rature range 450-900 K at heating rates of 1, 2 and 5 K min The t.g.a. curves indicated two principal reactions, distinguished by significan t and distinct mass changes over the experimental range. The pyrolysis of coated paper could be adequately described by a two-reaction model . The corresponding activation energies, pre-exponential factors and r eaction orders were determined. The experimental results were satisfac torily fitted by the proposed model. (C) 1997 Elsevier Science Ltd.
