摘要

A new technology for treating waste plastics (WP) by traditional coking process was introduced. With a thermo-balance and a 10 g atmospheric fixed bed reactor, the thermo-gravimetric behavior and product were studied during co-coking of WP with blended coal. And then, using a coke-oven with capacity of 200 kg, the characteristics of products were assessed. The results showed that there is an overlapping temperature range (200 - 550 deg C) of decomposition between WP and blended coal, and the pyrolysis synergism index eta and synergism strength beta proposed could evaluate the synergism between them. 1 percent of added WP results in the maximum synergism in all series experiments. The increase of added WP decreases the synergism. Tar yield in co-coking is increased with the decrease of water yield for synergism. Moreover, it was also found that the quality indexes of coke, such as M_(10) , M_(40), CRI and CSR, are degraded with the increase of WP until 4 percent, though the quality of tar and gas is optimized for WP addition.
