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 ...
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...
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...
IM-5 zeolite is synthesized in solutions of sodium hydroxide, sodium aluminate, and silica gel, along with N-methyl pyrrolidine and 1,5-dibromopentane by one-pot hydrothermal method. The method described in this paper is more convenient and environmentally benign than the conventional one, in whi...
