Embodiment 1-7、 comparative example 1
[0041] (1) 10g spent catalytic cracking catalyst is put into crucible, according to the condition shown in table 1, roast in microwave muffle furnace;
[0042] (2) The product of step (1) is put into the container, and the aqueous solution of organic phosphonic acid compounds is added according to the conditions shown in Table 1 under stirring conditions for contact treatment;
[0043] (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.
[0044] (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.
