A method of making a molecular sieve catalyst by preparing a catalyst slurry containing molecular sieve, binder and a matrix material and directing the slurry to a forming unit. The catalyst slurry is prepared by using a microfiltration process whereby the molecular sieve is washed and concentrated
A method of making a molecular sieve catalyst by preparing a catalyst slurry containing molecular sieve, binder and a matrix material and directing the slurry to a forming unit. The catalyst slurry is prepared by using a microfiltration process whereby the molecular sieve is washed and concentrated from a preparation medium without having to isolate the molecular sieve in a dry or semi-dry form. The catalyst is used to make ethylene and propylene from an oxygenate.

(1) a first deodorant material comprising at least one component selected from the group consisting of an inorganic element, a polyorganic acid, a salt of said acid, an ester of said acid, and active carbon; (2) a second deodorant material comprising at least one hydrazide compound; and (3) a synthetic resin binder. 2. A deodorant fibrous material according to claim 1, wherein said inorganic element comprises at least one compound selected from the group consisting of metallic compounds of copper, zinc, silver, lead, iron, aluminum, calcium, magnesium, manganese, nickel and cobalt. 3. A deodorant fibrous material according to claim 1, wherein said inorganic element comprises a porous substance and a copper compound. 4. A deodorant fibrous material according to claim 1, wherein said inorganic element comprises a porous substance and a zinc compound. 5. A deodorant fibrous material according to claim 1, wherein said inorganic element is a porous substance comprising at least one material selected from the group consisting of silicon dioxide, titanium dioxide, zinc oxide, aluminum oxide, zeolite, silica gel and active carbon. 6. The deodorant fibrous material according to claim 5, wherein said porous substance has an average particle diameter of 0.3 to 100 μm. 7. The deodorant fibrous material according to claim 5 wherein said porous substance has a specific surface area of 10 to 150 m2/g. 8. A deodorant fibrous material according to claim 1, wherein said first deodorant material is uniformly dispersed on the surface of the fibrous material. 9. A deodorant fibrous material according to claim 1, wherein the deodorant composition additionally comprises, as an emulsifying dispersing agent for said first deodorant material, a polyvinyl alcohol having a molecular weight of about 2,000-100,000 or a fibrous material-penetrating solvent. 10. A deodorant fibrous material according to claim 1, wherein the synthetic resin binder is at least one resin selected from the group consisting of urethane based resins, acrylic based resins, aminoplast resins, epoxy resins, glyoxal based resins and ethylene urea based resin. 11. A deodorant fibrous material according to claim 1, wherein the fibrous material is a polyester fiber. 12. A deodorant fibrous material according to claim 11, wherein the polyester fiber contains a cycloalkane halide compound as a flame retardant agent. 13. A deodorant material according to claim 1, wherein the second deodorant material is a hydrazine compound selected from the group consisting of hydrazide adipate and hydrazide malate. 14. The deodorant fibrous material according to claim 1, wherein the amount of said component of said first deodorant material attached to said surface is 0.05 to 10% owf relative to said fibrous material. 15. A deodorant fibrous material, comprising a fibrous material having a surface to which is attached a deodorant composition comprising: (1) a first deodorant material comprising at least one component selected from the group consisting of an inorganic element, a polyorganic acid, a salt of said acid, an ester of said acid, and active carbon; (2) a second deodorant material comprising at least one hydrazine compound; and (3) a synthetic resin binder, wherein the deodorant composition additionally comprises, as a flame retardant agent, a copolymer of a polyalkylene glycol with an aromatic dicarboxylic acid and an alkylene glycol. 16. A deodorant fibrous product formed from a deodorant fibrous material comprising a fibrous material having a surface to which is attached a deodorant composition comprising: (1) a first deodorant material comprising at least one component selected from the group consisting of an inorganic element, a polyorganic acid, a salt of said acid, an ester of said acid, and active carbon; (2) a second deodorant material comprising at least one hydrazide compound; and (3) a synthetic resin binder.
