采用二氧化硒作催化剂,在间歇反应装置中进行催化减粘裂化的研究.试验结果表明,在390℃的反应温度下,加入0.2%的二氧化硒可比不加时多获得轻馏分油1.26%,减压渣油降粘率提高5.1%.
Using selenium dioxide as catalyst, catalytic cracking in a batch reactor was studied.The experimental results show that adding 0.2% selenium dioxide at the reaction temperature of 390 ℃ can obtain 1.26% , Vacuum residue viscosity reduction rate increased by 5.1%.
