添加剂在强化催化裂化中的应用(Ⅰ)——不同复合表面活性剂对活化状态的影响
The Applying of Surfactants on the Intensified FCC(Ⅰ) ——The Effects of Different Compound Surfactants on Active State
摘要
Abstract
In this article, petroleum disperse system is applied to researchth e changeable situation of solidifying point, refractive index and conductance of the samples when a certain amount of thinner and three kinds of compound surfac tants with different HLB values are added into the samples of Daqing crude m ix es with 26% of Liaohe residue. The results indicate that number one, number two and number three surfactant have the active effect on the system. When the quant ity of the thinner and the compound surfactants are 1%and 1‰ respectively, the solidifying point, refractive index and conductance of the sample are the minim um, that is, the system is just in the active state. Then the sample as the feed stock was put int o catalytic cracking react operator of reconstructed mini fluid fixed bed when temperature is 500 ℃, feedstock is 13.5~14.5 g, catal yst/oil ratio is 6, LHSV is 20 h-1, reaction pressure is normal. The intensif ied fu nctions have been determined by measuring the yield of products with different c atalyst under various operation conditions. The results show that a certain amou nt of the thinner and the compound surfactants can change the dispersion degree of the petroleum disperse system. The results of FCC indicate that dry gas decre ase 2.5% to 3.5%, coke yields decrease 1.5% to 2.5%, LPG yield increase 2.5% to 3.5%, gasoline yield increase 2.5% to 3.5%, diesel oil decrease 0.3% to 1.0% i n the active state.关键词
