查询词典 dip-moulding

The present invention adopts the technical proposal of adopting ZSM-5 mesoporous molecular sieve raw powder with a silicon-aluminum mol ratio SiO2Al2O3 of 20 to 1000 and a weight percentage of 20 to 100 percent as well as at least one caking agent selected from SiO2, clay and Al2O3 to extrude, tablet or spray into shape; then treating for 1 to 8 hours by 0.1 to 3 mol/l of at least one ammonium liquor from ammonium nitrate, ammonium chloride or ammonium sulphate or 0.1 to 8.5 mol/l of at least one acid liquor from muriatic acid, nitric acid, vitriol or acetic acid under a temperature of 20 to 90 DEG C; then using steam to treat for 2 to 15 hours under the temperature condition of 400 to 700 DEG C; using a liquor of 0.1 to 3mol/l selected from at least one of oxalic acid, citric acid or maleic acid under a temperature condition of 20 to 90 DEG C to dip for 2 to 5 hours to obtain the modified molecular sieve catalyst, thus better solving the problems.

本发明通过采用硅铝比SiO2/Al2O3为20～1000重量百分比计20～100％的ZSM-5介孔分子筛原粉与余量的选自SiO2、粘土或Al2O3中至少一种粘结剂挤条、压片或喷球成型；再经过0.1～3摩尔/升选自硝酸铵、氯化铵或硫酸铵中的至少一种铵溶液或0.1～8.5摩尔/升选自盐酸、硝酸、硫酸或乙酸中的至少一种酸溶液在温度20～90℃下处理1～8小时；然后在温度为400～700℃条件下水蒸汽处理2～15小时；再用0.1～3摩尔/升选自草酸、柠檬酸或马来酸中至少一种在温度为20～90℃条件下浸渍2～5小时得所需改性分子筛催化剂的技术方案较好地解决了该问题，可用于甲醇转化制丙烯的工业生产中。
