The molecular kinetic model and the simulative calculation of the Lummus SRT-Ⅳ cracking furnace with the HVGO (Heavy/ Hydrotreated vacuum gas oil) have been finished in this paper. The main contributions are as follows: Firstly, the investigative actualities of the petroleum alkyl pyrolysis and the developmental trend in this field have been described. Different kinds of the theories of hydrocarbon cracking and coke kinetics during the pyrolysis process, and the basic methods of modeling have been studied. Secondly, the ethylene pyrolysis process kinetic model in one domestic plant by using SRT-Ⅳ cracking furnace with the HVGO, and the Hirato model has been finished. A random searching algorithm has been used to adjust the initial selectivities of the primary reactions for the Hirato model. This algorithm can achieve both the C-H equivalence and a high precision of the simulative results. The Treanor numeric integral algorithm has been used to simulate the model, and the compare of the results with the yields data from real furnace of an ethylene plant has been made. Thirdly, based on the model built above, the variations of the distribution of the outlet yields have been investigated by changing the operation conditions (the outlet temperature, the rate of flow and the S/O ratio) and the coke layer thickness. This work would be useful to predict the period of get ride of coke. Finally, the results have been summarized during this design, the possible problems and some incomplete aspects existing in the model build above have been analyzed, and some prospects of the aftertime works have been made.

The correlation between these factors and coke thermal properties was found, then coke thermal properties control model was established. Also, the methods of improving coke thermal properties by negative catalyst addition and chemical vapor deposition were examined. Finally, the mechanism of coke thermal properties improvement deduced from the results of these two approaches was investigated. 1. Summarizing the foreign and domestic coke quality prediction methods, using improved GHMP mathematics method, a coke thermal properties control model is established on the basis of 19 coals and 64 coal blends carbonized in a simulated coke oven. The model is an effective method to get high-grade coke by coal blending. According to the research about the model, existed mineral catalysis effect is one of the key factors affecting coke quality besides the coal rank and the plastic properties of coal.
在总结国内外焦炭质量预测模型的基础上，采用了最新发展的GMDH方法作为数学模型的创建工具，以19种单种煤和64个配煤在SCO炉上的试验数据为基础，建立了适用于大生产焦炭的溶损反应性控制模型，并研究了焦炭热性质的影响因素及其作用大小，结果表明：与焦炭反应性相关的主要因素是煤的矿物质的催化作用、煤的镜质组随机反射率、基氏流动度、惰性物含量以及型煤配比；与焦炭反应后强度相关的主要因素为煤矿物质的催化指数、煤的挥发分、基氏流动度、惰性物含量以及型煤配比；煤质数据参数及其相互作用对煤的粘结性和焦炭热性质有较大影响，煤中矿物质与焦炭热性质也有密切关系；继而提出采用负催化剂和化学沉积气相技术抑制溶损反应，降低焦炭反应性，提高反应后强度的有效新途径。
