Recently, the China Non-ferrous Metals Industry Association hosted the scientific and technological achievements appraisal meeting of “NaY Molecular Sieve Production Technology†undertaken by Shandong Aluminum Co., Ltd. in Zibo City, Shandong Province. The appraisal committee heard the project's research report, reviewed the relevant appraisal materials, visited the site, and after questioning and discussion, experts believed that the NaY molecular sieve production technology has achieved industrial applications and has the following technical features and innovations: 1. The process materials From the alumina plant, the crystallization mother liquor is used to produce 4A zeolite and X zeolite, eliminates the discharge of waste liquid and waste residue, reduces the production cost of NaY molecular sieve, and meets the environmental protection requirements; 2. The full use of crystallization mother liquor , Do not return to the batching system, greatly shortening the crystallization time; 3. Excellent product quality: crystallinity ≥ 90%, silicon-aluminum ratio ≥ 5.3. 4. The use of advanced synthesis tank, large volume, high mixing speed, improve production efficiency .
The project has been applied to production, the technology is reasonable, the product quality is stable, and it has received good economic and social benefits. Experts believe that the overall technology of the project has reached the leading domestic level and has a good promotion prospect.
