preparation example Construction
[0030] A preparation method for high-efficiency oil fume adsorption molecular sieves, comprising the steps of:
[0031] The ceramic fiber carrier is soaked in lye, washed with water and dried to make a honeycomb mesh matrix;
[0032] After mixing diatomite, attapulgite, kaolin and 13x molecular sieve raw powder, grinding, sieving and mixing with silica sol aqueous solution to obtain a slurry;
[0033] Immersing the slurry on the surface of the honeycomb mesh matrix, and obtaining the honeycomb carrier with the slurry attached after soaking;
[0034] The honeycomb carrier attached with the slurry is dried and then calcined to obtain a high-efficiency oil fume adsorption molecular sieve.
[0035] Further, the lye used for soaking the ceramic fiber carrier with lye is sodium hydroxide with a mass fraction of 2%, and the immersion time is 30 minutes; after the ceramic fiber carrier is washed with water, the pH value of its surface is less than 8; The treatment method adopted in ...
