According to the approximation ability of WNN, the nonlinear system is able to be modeled, obvious effect was shown in process modeling of residuum cracking and prediction of asphaltum yield and pyrolysis gas yield.

利用小波网络的逼近性，对非线性系统进行建模和预测，通过渣油裂解的实例，将小波网络与RBF网络作为对比，可以看出，小波网络的建模和预测效果都优于RBF网络。

The survival needs privately operated to cause China to refine oil theenterprise to carry on the technological innovation, the wastage -residual oil which overseas refines oiltreats as the raw material to carry on two times of processings,because the bunker oil cost compares the crude oil to be low, bringsthe certain processing profit for the privately operated refinery,thus also has formed the every year nearly 70 million tons bunker oilsgiant markets.

生存的需要使中国民营炼油企业进行技术革新，把国外的炼油的副产品—渣油当作原料进行二次加工，由于燃料油成本较原油低，给民营炼油厂带来一定的加工利润，从而也就形成了每年将近7000万吨燃料油的巨大市场。

渣油经过加氢裂化反应后，虽然其芳炭率提高了，但是它的芳香环系缩合度降低了，表明在加氢中有大量的烷基侧链断链反应发生。

The experimental results showed that the product distribution and selectivity of the deasphalted oil from vacuum residuum was better than that from gasoline while the deasphalted oil from FCC slurry oil was worse than gasoline.

研究发现，减压渣油和掺兑催化油浆的减压渣油的丙烷脱沥青油具有较好的产物分布和选择性；而催化油浆的脱沥青油的裂化性能较差。

Several deasphalted oil samples were obtained from vacuum residuum and FCC slurry oil deasphalted at continuous propane deasaphalting pilot equipment.

研究发现，减压渣油和掺兑催化油浆的减压渣油的丙烷脱沥青油具有较好的产物分布和选择性；而催化油浆的脱沥青油的裂化性能较差。

The experiments for determining the reaction kinetics of Daqing atmospheric residue were performed in a continuous flow, expanded bed rector. Four-lumped reaction kinetic model was developed to account for various feed and product fractions of Daqing atmospheric residue (gases, gas oil, residue and coke). The amounts of olefins and alkyls in the gas products were further analyzed to determine reaction kinetics of gas product distributions. Hence, a combined five-lumped reaction kinetic model was obtained for catalytic pyrolysis of Daqing atmospheric residue. The kinetic constants both in four-lump model and five-lump model were evaluated. A simulator for catalytic pyrolysis process was developed by incorporating the five-lumped kinetic model into the hydrodynamic flow model.

其次利用改进的固定流化床装置考察大庆常压渣油催化裂解反应规律，筛选反应工艺参数；分析了催化裂解工艺存在的主要化学反应类型，提出了渣油一次反应和二次反应网络图；将反应原料油作为单独集总组分，而将产品中的轻质油、气体、焦炭分别作为集总，从而建立了四集总动力学模型；在此基础上，把气体产物中的目的产物低碳烯烃独立划分，得到五集总动力学模型；采用最小二乘法分析实验数据，分别得到四集总动力学模型和五集总动力学模型中各集总间相互反应转化的反应速率常数。
