Abstract

This paper explores the basic features of the pyrolysis of CCL (Copper Clad Laminate scrap) that is mainly composed of carbon fibers and phenol resins. Non-isothermal thermogravimetric analysis (TGA) was introduced to investigate pyrolysis kinetics of Copper Clad Laminate (CCL) waste at three heating rates of 10, 20, and 30oC/min. A batch reactor was used to investigate the distribution patterns of pyrolysis by-products of CCL at operating temperatures of 350oC and 600oC. The pyrolysis of CCL is likely to be accounted for by a three-stages series reaction model. The first stage is represented by H2O generation that may be achieved by the reaction of hydroxyl group (OH) with hydrogen in CCL. The phenol resins are mainly decomposed at the second stage reaction. The third stage is represented by stabilization process of solid by-products. At the third stage, thermally stable compounds bounded to solid by-products seem to be decomposed slowly and consequently, the solid by-products are converted to char via the slow decomposition processes. Owing to high heating values, pyrolysis by-products can be used as fuel. However, high content of nitrogen should be properly controlled before using the by-products as fuel.
