随着重油催化裂化的发展 ,原料雾化困难日益成为严重的问题 ,传统工艺只能获得 60～12 0 μm的液滴。重油和水在乳化剂的作用下 ,形成油包水型乳化液。采用该种乳化重油作为催化裂化原料 ,以“微爆”学说和“分子聚集与解聚”理论为基础 ,与传统工艺相比 ,可以获得粒径更小的液滴 ,从而改善产品分布。根据小型固定流化床的乳化实验数据 ,采用三因子逐步回归分析方法 ,对乳化原料的转化率以及各产品 (气体、汽油、柴油、重油、焦炭 )产率与反应温度、剂油比、乳化剂用量进行关联 ,得到了一组回归方程 ,利用该回归方程计算所得数据 ,通过F检验 ,结果表明该组关联式有显著的关联性 ,回归效果较好。这组回归方程可以应用于此工艺工业应用的初步设计和技术经济分析
With the development of catalytic cracking of heavy oil, the difficulty of atomization of raw materials is becoming a serious problem day by day. Only 60 to 120 μm droplets can be obtained in the conventional process. Heavy oil and water in the emulsifier role, the formation of water-in-oil emulsion. Based on the theory of “microburst” and “molecular aggregation and depolymerization”, the emulsified heavy oil is used as a raw material for catalytic cracking. Compared with the traditional process, smaller droplets can be obtained and the product distribution can be improved. According to the data of emulsification experiment of small fixed fluidized bed, the conversion of emulsified raw materials and the yield of each product (gas, gasoline, diesel, heavy oil, coke) and reaction temperature, The correlation between the dosage and the dosage was obtained, and a set of regression equations was obtained. Using the regression equation to calculate the data, the result of F test showed that the correlation was significant and the regression effect was good. This set of regression equations can be applied to the preliminary design and technical and economic analysis of this process industry application
