Embodiment 1
[0019] A preparation method for catalytic cracking high liquid yield agent, comprising the following steps:
[0020] (1) Preparation of zinc solution: pump 20kg of water, 30kg of monoethanolamine, and 30kg of tartaric acid into the reactor and stir evenly, then raise the temperature to 70°C and slowly add 20kg of zinc oxide, then raise the temperature to 103°C, reflux for 1 hour, and cool to 50°C ℃ into an orange clear solution for later use;
[0021] (2) Preparation of antimony and cerium bimetallic solution: put 20kg of water, 15kg of monoethanolamine, 25kg of tartaric acid, and 25kg of antimony white into the reactor and stir for 30 minutes, heat up to 102°C, reflux for 1 hour, and cool down to below 50°C. Add 5kg of monoethanolamine, heat up to 70°C, slowly add 10kg of cerium carbonate, continue to heat up to 108°C, reflux for 1 hour, cool to below 50°C and discharge, set aside;
