摘要
采用盐酸对催化裂化(FCC)催化剂废渣进行改性,并用于润滑油的补充精制,利用XRF和FTIR等方法分析了FCC催化剂废渣改性前后的性质,并考察了精制条件对润滑油精制效果的影响。实验结果表明,FCC催化剂废渣改性后,比表面积增大、孔体积略有增加、活性度提高。改性FCC催化剂废渣用于润滑油精制时,较适宜的精制条件为:FCC催化剂废渣用量(基于润滑油质量)10%(w)、精制温度100℃、精制时间30 min、搅拌转速100 r/min。采用溶剂抽提法对含油改性FCC催化剂废渣进行再生和二次改性,再生FCC催化剂废渣经二次改性后仍对润滑油具有良好的精制效果。循环使用FCC催化剂废渣有利于降低生产成本及对环境的污染。
Fluid catalytic cracking (FCC) catalyst residue was modified with HC1 and used in lube oil finish refining. The FCC catalyst residues before and after the modification were characterized by means of XRF, FTIR. The effects of the refining conditions on the properties of the refined lube oil were investigated. The results indicated that the specific surface area, pore volume and activity of the FCC catalyst residue were improved by the modification. The optimum conditions for lube oil finish refining were: modified FCC catalyst residue dosage (based on the mass of lube oil) 10% (w), finish refining temperature 100 ℃, time 30 min and stirring speed 100 r/min. The modified FCC residue could be recycled by solvent extraction and remodified. The remodified FCC catalyst residue showed good performance in the lube oil finish refining.
