Embodiment 1-9γ comparative example 1-2
[0045] (1) 10g spent catalytic cracking catalyst is put into crucible, according to the condition shown in table 1, roast in microwave muffle furnace;
[0046] (2) The product of step (1) is put into the container, and is processed with acid solution according to the conditions shown in Table 1;
[0047] (3) Cool the product of step (2) to room temperature, suction filter, wash with deionized water to neutrality (pH=7), and dry in a blast drying oven according to the conditions shown in Table 1 to obtain revived catalytic cracking catalyst.
[0048] (4) The Ni removal rate, V removal rate and micro-reaction activity of the revived catalytic cracking catalyst obtained were measured respectively, and the results are shown in Table 2.
