摘要：

The objective of the present study was to investigate the leachability of two spent catalysts used for hydrotreating of distillates and two spent catalysts used for hydrocracking of heavy feedstocks. The Toxicity Characteristic Leaching Procedure (TCLP), developed by the U.S. Environmental Protection Agency (EPA), was applied to determine levels of priority inorganic pollutants and compare them with EPA's regulatory levels. The concentrations of metals, not included in the list of priority pollutants, were also determined.
