摘要
Abstract
An 8-lump kinetic model is proposed for Daqing naphtha pyrolysis based on the analysis of experimental data obtained in a self-designed cracking experiment device. A computational program was written by Marquardt~(++) method and Matlab language and kinetic constants were calculated. The error analysis showed that most of the apparent activation energies are between 112 and 317 kJ · mol~(-1), the raw material lump relative error is approximately about 10%, while the relative error for the main target products is basically within 7%, in which the average relative error for ethylene yield is 1. 62%. The proposed model can describe the reaction process of Daqing naphtha pyrolysis and predict the distribution of products.关键词
