Industrial Applications of Molecular Scale Kinetic Model in Delayed Coking

Based on the industrial rating data,a molecular kinetic model of delayed coking was used to simulate the feedstock and products in a delayed coking process in industrial reactors in Gaoqiao Petrochemical Co.of China Petroleum & Chemical Corporation.When the number of generated molecules is(between) 1 000 and 5 000,these molecules reflect the characters of feedstock very well.When the mole-(cule number) is 4 000,the process is more stable and the relative error of products is smaller.It was also(shown) that the model does reflect actual conditions well.
