| Abstract: | Na, Al, S, Cl, V, Mn, Ni, As, Br, I, La, Eu and Dy were determined in 2 feeds and 5 products of a catalytic cracking unit.
Catalysts used in this unit were also analyzed and 18 elements were measured in this matrix. The overall mass balance of the
unit was calculated and it was shown that the concentrations of most elements are reduced during cracking but the concentrations
of some others (Al, Dy, Eu and La) are increased. |
