실험 절차

This example illustrates the loss of zeolite activity or conversion from conventional selectivation techniques that use compounds which are small enough to enter the zeolite channels. An aqueous solution of magnesium nitrate was prepared by mixing magnesium nitrate hexahydrate and water on the basis of 0.71 gram per gram of water. The solution was used to impregnate a ZSM-5 (SiO2/Al2O3=38) zeolite powder at a ratio of 1.35 cc solution to 1.50 g of zeolite. The mixture was heated at 75° C. to evaporate the water. It was then dried at 120° C. for 6 hours, at 250° C. for ½ hour, and at 300° C. for ½ hour, and then calcined at 500° C. for 3 hours. Analysis of the zeolite sample indicated that 0.06 gram of magnesium oxide per gram of zeolite was deposited on the zeolite.
