Embodiment 1
[0021] 1) Weigh the following raw materials in parts by weight: 65 parts of NaX molecular sieve powder; 15 parts of ocean crucible; 13 parts of sepiolite; 1.5 parts of phenolic resin; 2 parts copper;
[0022] 2) Mix and ball mill NaX molecular sieve raw powder, ocean crucible, sepiolite, ammonium chloride, and copper oxide in step 1) to 250-300 mesh, then add it to the reaction kettle, and keep it under sealed conditions at a temperature of 90-120°C Thermal crystallization under water for 20-24h;
[0023] 3) Precipitate, wash, and dry the material after hydrothermal crystallization in step 2), and then dry it at a temperature of 160-200°C;
[0024] 4) Cool the dried raw materials in step 3) to room temperature, mix them evenly with phenolic resin and carboxymethyl cellulose, granulate or extrude, and bake at 675°C for 2 hours to obtain mercaptan removal With Cu molecular sieve catalyst.
