| 摘 要： | 废油和废催化裂化(FCC)催化剂是两类难处理的危险废弃物。为了循环利用这两种废物,本文使用废催化裂化催化剂吸附再生基础油中的碱性氮,从而提高其品质。当吸附温度为150℃,剂油比为10%,废FCC催化剂为400目时,吸附条件最佳;结果显示该条件下,再生基础油色号为7,碱性氮含量为0.62 ppm,碱性氮含量降低百分比高达94%,满足重复使用的标准。

| Abstract: | Waste oil and waste Fluid Catalytic Cracking(FCC)catalyst are two types of refractory hazardous wastes.To recycle both the wastes,waste FCC catalyst is utilized to adsorb the basic nitrogen in base oil,hence improving its quality.The adsorption condition is optimal when the adsorption temperature is 150℃and agent/oil,10%using 400 mesh waste FCC catalyst.The results show that the regenerated base oil color number is 7 and the basic nitrogen content,0.6241ppm with the 94%reduction percentage of basic nitrogen under the above condition,which meet the standards for recycle. |
