[0036] (Example 1)
[0037] see Figure 1 to Figure 3 , A method for preparing rare earth element catalytic cracking bimetal passivator, the specific steps are:
[0038] A. Mix 300~600kg mother liquor A, 50~150kg mother liquor B and pH adjuster 5~20kg;
[0039] B. 30 to 80 kg of non-ionized water, stirring for 30 to 60 minutes to discharge.
[0040] The preparation steps of mother liquor A are:
[0041] a. Add 6-20kg of pH adjuster, 10-35kg of organic acid, and 20-80kg of organic amine into a 500kg reaction flask, and stir for 10min;
[0042] b. Add 80~120kg of antimony powder, and the temperature will continue to rise by 80~100℃, add 100~170kg of oxidant dropwise;
[0043] c. Condensation and reflux for 1-2h,
[0044] d. Add 15~35kg of stabilizer, stir and cool to room temperature, and discharge to obtain mother liquor A.
[0045] The preparation steps of mother liquor B are:
[0046] a. Add 100~150kg of rare earth powder, 100~140kg of organic acid, and 100~200kg of non-ionized water int...
