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.
