Estimating the term…
This invention relates to an EUO-structural-type zeolite that comprises at least one element X that is selected from among silicon and germanium and at least one element T that is selected from among aluminum, iron, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese. The zeolite of the invention has an X/T ratio of between 5 and 50 and an N/T ratio of between 0.010 and 0.065. This invention also relates to the use of the EUO zeolite as a catalyst in a process for conversion of hydrocarbon feedstocks and more particularly in a process for isomerization of aromatic compounds with 8 carbon atoms per molecule.
An EUO zeolite comprising nitrogen N, at least one element X selected from the group consisting of silicon and germanium, and at least one element T selected from the group consisting of aluminum, iron, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese, said zeolite having an X/T ratio of between 5 and 50 and an N/X ratio of between 0.010 and 0.065.
In a process comprising conducting a reaction in contact with a catalyst, the improvement wherein said catalyst comprises a catalyst in accordance with claim 24, said reaction being any of isomerization, transalkylation and dismutation, alkylation and dealkylation, hydration and dehydration, oligomerization and polymerization, cyclization, aromatization, cracking and hydrocracking, reforming, hydrogenation and dehydrogenation, oxidation, halogenation, amine syntheses, hydrodesulfurization and hydrodenitrification, catalytic elimination of nitrogen oxides.
