- Abstract: A pressurization vessel instead of the original vented vessel was used to determine the aluminum oxide content in FCC catalyst to enhance its solubility in acid solvent.
- The acid solvent of extraction was used m both the Bray and Truog methods. The strong alkaline solvent of extraction was used in Al-Abbas method. These methods showed to be unsuitable for the desert soils.
