The present invention relates to a dealuminated IM-5 zeolite and to any catalyst comprising that zeolite which is at least partially in its acid form. The invention also relates to the preparation of the catalyst and to the catalyst. Finally, the invention relates to the use of the zeolite ...
A IM-5 zeolite synthesis method, comprising the steps of: (1) an inorganic base, an aluminum source, templating agent dissolved in deionized water, mixed to prepare a mixed solution; the mixed solution (2) to the step (1) added solid silica template agent precursor added, mixed, made of...
The invention concerns IM-5 zeolite with a chemical composition with the following formula, expressed in terms of the mole ratios of the oxides for the anhydrous state: 100XO2,mY2O3, pR2/nO where m is 10 or less; p is in the range 0 to 20; R represents one or more cations with ...
As for catalytic cracking reaction, the microporous IM-5 zeolite obtained by direct synthesis usually has limited diffusion rate and too high amount of Brønsted acid sites [31,32], which led to secondary reactions and fast deactivation. To improve the catalyst lifetime and the light olefin yie...
IMF – Calcined IM-5This chapter presents the zeolite framework types (nomenclature), composition (chemical and refined), crystal data, reference, powder pattern identification table, simulated powder pattern, and calculated powder diffraction data of calcined IM-5 [Si 288 O 576 ]....
