Methods for Modifying a ZSM-5 Type Zeolite to Alter the Activity of the System of Hydrogen Transfer Reactions in the Cracking of Lower Aliphatic Alcohols
The influence of the alkali treatment of ZSM-5 zeolites with a silica ratio of 30 within the NaOH : SiO2 molar ratio of 0 : 230, as well as the modification of a ZSM-5 zeolite with phosphorus in the range of 0-8 wt %, on the physicochemical properties and activity in hydrogen transfer reactions in the case of conversion of aliphatic alcohols has been studied. The alkali treatment of the zeolite leads to a decrease in the zeolite silica ratio and a growth in the hydrogen transfer coefficient in the case of transformation of aliphatic alcohols. The modification of the zeolite with phosphorus is equivalent to an increase in the zeolite silica ratio, which leads to a decrease in the hydrogen transfer coefficient.
