Recently, the catalyst business department of Lanzhou Petrochemical Company adopted the new process of "non-ammonium method" to produce HRSY-5 molecular sieve and structurally stable molecular sieve products, and all quality indicators reached the standard
In the production process of molecular sieve, ammonium sulfate is used as an exchange medium to reduce the content of sodium oxide in the product to ensure the stability and activity of molecular sieve
Lanzhou Petrochemical Catalyst Division actively promotes the application of new processes, and tries to apply the new process of "ammonium-free method", which reduces the production cost of molecular sieves by adjusting the amount of rare earth added to replace ammonium sulfate
In the production process, the staff of Lanzhou Petrochemical Catalyst Division control the material exchange temperature, pH value and other indicators, and accurately control the tank transfer and recovery volume and other indicators in response to the problems of unsmooth material filtration in the new process of "ammonium-free method".
