摘要：

The effect of the temperature and exposure time of the starting aluminophosphate gels on their chemical and phase composition was studied. When the source of aluminum is its hydrated oxide (boehmite), gels with different contents of ammonium phosphate, undissolved boehmite, and amorphous aluminophosphate can be formed. The formation of a gel with dominant amorphous aluminophosphate allows selective crystallization of AlPO4-11 of high phase purity and 100% crystallinity. The developed procedure for the preparation of highly dispersed aluminophosphate AlPO4-11 molecular sieves with these properties allows a transition to crystallization of silicoaluminophosphates SAPO-11promising domestic catalysts for industrial hydroisomerization of n-paraffins in the production of Arctic diesel fuels and group III oils and isomerization of butenes.
