Removal of contaminating metals from FCC catalyst by NH4 citrate chelates |
摘要 |
A contaminating metal on a cracking catalyst used for the cracking of hydrocarbons is removed by contacting the catalyst with a chelating agent which forms chelates with the contaminating metal. The chelates containing the contaminating metal may be readily separated from the catalyst.
