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。

But the snow is falling heavily, in great soft flakes, so that you can hardly see across the shallow valley, and the roofs are thick and the trees all bending, and the weathercock of the village church, still to be seen through the gray loaded air, has become some creature out of Hans Andersen.
