将掺渣蜡油乳化成 W/O乳液 ,作为催化裂化原料油 ,在二次雾化和分子解聚作用下 ,可显著改善原料油雾化状况 ,降低结焦和干气收率。研究了掺渣蜡油的乳化过程 ,包括乳化剂的单剂筛选和复配以及乳化工艺条件。结果表明烷基酚聚氧乙烯醚 (M-2 )具有较好的乳化性能 ;乳化剂的复配能增加乳化原料油稳定性 ;适宜的掺水量是 w水 =0 .1 0～ 0 .1 5 ,加剂量为 w乳化剂 =0 .0 0 1～0 .0 0 1 2 5 ;乳化温度 70°C～ 80°C;乳液体系中水珠分布直径为 5μm～ 1 0μm,乳化原料油在 80°C时油水分层时间达 1 4d
The mixed wax oil emulsified into W / O emulsion, as a catalytic cracking feedstock oil, under the secondary atomization and molecular depolymerization, can significantly improve the feedstock atomization conditions, reduce coking and dry gas yield. The emulsification process of mixed paraffin oil was studied, including the single agent screening and compounding of emulsifier and the process conditions of emulsification. The results showed that alkylphenol polyoxyethylene ether (M-2) had good emulsifying properties; the emulsifier compounding could increase the stability of the emulsified feedstock oil; the optimum water content was w water = 0.001 ~ 0.1 5, the dosage is w emulsifier = 0 0 1 ~ 0. 0 0 1 2 5; emulsifying temperature is 70 ° C ~ 80 ° C; the diameter of the droplets in the emulsion system is 5μm ~ Oil and water stratification time reaches 14d at 80 ° C
