-12 PROCESS FOR ISOSOMERIZING A HYDROCARBONACEOS FEEDSTOCK USING ALUMINOSILICATE ZSM-12

摘要

Aluminosilicate ZSM-12 can be newly prepared in the form of small crystals from the reaction mixture comprising a silica source and an alumina source. Aluminosilicate ZSM-12 in the form of small crystals can also be prepared from borosilicate ZSM-12 in the form of small crystals by replacing boron in the borosilicate ZSM-12 framework with aluminum. Aluminosilicate ZSM-12 is useful as an isomerization-selective catalyst in processes such as isomerized hydrocarbon feed dewaxing.
