Application of Partial Least Squares in Parameter Analysis for Carbon-Black Production Li Jinming ， Li Menglong*， Yin Jiajian， Jiang Wei (Faculty of Chemistry, Sichuan University, Chengdu 610064) Abstract In terms of the production of carbon black by means of experience principally, and for promoting carbon black production technology, partial least squares(PLS) is applied to the analysis of the data from production process, and the mathematics model between parameters and targets is set up. After the affected extent of each parameter to iodine specific surface area(ISSA) and DBP absorption is parsed, primary parameters and assistant parameters are found out. Based on the computed results, how to adjust production parameters for improving product quality of carbon-black is discussed in detail. Subsequently, the results from PLS are applied to guide the actual production, satisfactory effectiveness is gained, and the ability for producing high quality carbon black is improved.
