Аннотация: The work is aimed at a fundamental study of the formation of acid sites in MFI zeolites obtainedin a fluoride medium using Aerosil, silica gel, and silica sol as sources of silicon. The synthesized sampleshave been characterized by a set of instrumental methods and tested in the reaction of methanol conversionto hydrocarbons. It has been shown that the synthesis of MFI zeolite in a fluoride medium leads to the insertionof aluminum into the tetrahedral positions of the zeolite framework to form isolated acid sites. Moreover,the type of amorphous source of silicon affects both the amount of incorporated aluminum and the size ofthe product crystals. It has been established that the use of silica sol as a silicon source leads to an increase inthe catalyst time-on-stream stability and a decrease in the selectivity for ethylene. The obtained result isexplained by an increase in the proportion of Al atoms localized in zeolite channels
