- Abstract
- This study examined the optimum pyrolysis conditions of polyurethane for the yield of a solid product with a high iodine number using central composite design (CCD) on the secondary model in response surface methodology (RSM). The temperature, heating rate and total heating time are factors influencing the yield of solid products. The temperature was estimated from the highest factor influencing the solid product yield (Y(1)) and the iodine number (Y(2)). The coefficient used for determining Y(1) and Y(2) were found to be 0.94 and 0.84 with a la-value of 0.0013 and 0.0361, respectively. The optimal values for the solid yield and iodine number were calculated from the second regression formula. The solid yield and iodine number were estimated to be 15 g and 582 mg/g under the optimum condition, respectively. Under the optimum conditions determined in this study, the experimental results were 14.8 g and 558 mg/g, respectively. (C) 2008 Elsevier B.V. All rights reserved.
